Figs. 41, 42  
 Deeveya exleyi Kornicker & Iliffe 1998: 53, figs. 37–42.—Kornicker et al. 2002: 23.   
 Holotype. USNM 194269, adult female.   
 Type locality. Oven Rock Cave, Great Guana Cay, Exuma Cays, Great Bahama Bank.   
 Material. Holotype plus USNM 1021450, A-4 instar (sex unknown) on slide.   
 Distribution. Great Bahama Bank: type locality and Norman’s Pond Cave, Norman’s Pond Cay, Exumas.   
 Supplementary description of adult female (Correction). Kornicker & Iliffe (1998: 57) described the first endopod segment of the mandible as having two posterior bristles. Examination of the holotype revealed that it has only one posterior bristle as shown in their illustration (Kornicker & Iliffe 1998: fig. 39f).   
 Description of A-4 instar (sex unknown) (Figs. 41, 42). Carapace oval in lateral view with linear dorsal margin (Fig. 41 a). Right valve with small glandular process at posterior end of dorsal margin (not shown).   
 Ornamentation: Surface in transmitted light with clear round spots (Fig. 41 c). Shell between clear spots with abundant fine hair-like striae. Single lateral bristle projecting from midheight of posterior margin; 1 divided lateral bristle anterior to midlength of ventral margin, and 2 single anteroventral bristles (not shown).   
 Selvage: Broad infold along anterior, ventral, and posterior margins. Broad lamellar prolongation with smooth outer edge along anterior, ventral, and dorsal margins.   
 Central adductor muscle attachments (Fig. 41 b): Consisting of a cluster of about 9 attachments.   
 Carapace size (length, height in mm): USNM 1021450, 0.66, 0.55.   
 First antenna (Fig. 41 d,e): 1st segment with spines in distal ventral corner. 2nd segment with 1 dorsal bristle. 3rd and 4th segment fused, but slight indentation on dorsal margin indicates place of separation; 3rd segment with 1 ventral bristle; 4th segment with 1 short dorsal bristle. 5th segment with minute terminal ventral pointed nub (visible with oil immersion lens). 6th segment bare. 7th segment with short dorsal a-bristle and long ventral c-bristle. 8th segment with long d-, e-, and f-bristles, and short g-bristle. 1st and 2nd segments forming large angle.   
 Second antenna: Protopodite bare. Exopod with segment 1 partly divided into 2 parts, with small medial bristle near ventral margin. Segments 2 to 8 with long ventral bristle. Segment 9 with 2 bristles (1 short, 1 medium length). Endopod (Fig. 41 e,f): 1st segment with 1 dorsal bristle; 2nd segment with short f-bristle and long g-bristle; 3rd segment fused to 2nd segment, with long h-, i-, and j-bristles.   
 Mandible (Figs. 41 g –k, 42 a): Coxa endite with proximal and distal sets of teeth separated by space (Fig. 41 g,h): proximal set with about 4 stout cusps, surface between and adjacent to cusps with slender spines; stout pointed tooth between proximal and distal sets of teeth with spinous bristle adjacent to tooth. Distal set of teeth comprising 2 flat teeth, each tooth with 3 or 4 cusps (obscured); stout bristle between inner tooth and stout pointed tooth. Basis with 1 long slender bristle and 1 short bristle near base of endopod (Fig. 41 i,j), and 2 stout filamentous plumose dorsal bristles (Fig. 42 a). Basis endite with single anterior bristle; posterior margin with hairs and 2 short distal bristles (distal of these tubular) (Fig. 41 i); lateral side with 2 bristles (none entwined); ventral edge of endite with 5 terminal cusps (posterior of these smaller than others and set back from terminal edge), and 1 lateral tooth set back from edge (Fig. 41 i). Endopod (Fig. 41 j,k): 1st segment with 1 terminal dorsal bristle; 2nd segment with 2 or 3 bristles (2 dorsal (1 claw-like)), none or 1 ventral; 3rd segment with 4 bristles (1 very long)).   
 Maxilla (Fig. 42 b): Endite I with 7 bristles; endite II with 6 bristles; endite III with 5 bristles. Coxa with plumose dorsal bristle. Basis with 2 terminal ventral bristles. Endopod: 1st segment with 2 or 3 bristles (1 or 2 anterior, 1 posterior). 2nd segment with 1 claw-like bristle, 1 long stout spinous bristle, and 3 slender bristles (at least 1 tubular).   
 Fifth limb (Fig. 42 c–f): Epipod with plumose bristles forming 3 groups, with 3 bristles in each group on mounted specimen, but some bristles probably missing (about 13 counted on specimen prior to mounting, but view obstructed). Precoxa and coxa with total of 1 claw and 12 bristles (4 bristles tubular, 1 bristle nub-like, spinous) (Fig. 42 e). Basis with 4 bristles. Exopod represented by 2 bristles (1 long bare, 1 plumose). Endopod: 1st segment with 2 distal ventral bristles; 2nd segment with 2 long slender, somewhat clawlike bristles, and 1 short slender bristle.   
 Sixth limb (Fig. 42 f–h): Epipod fragmented, with plumose bristles. Precoxa and coxa without bristles. Exopod represented by small lobe with 3 long bristles. Endopod with 2 segments: 1st segment bare; 2nd segment with 2 terminal bristles (1 long, 1 short). Terminal segment not reaching past terminal segment of 5th limb (Fig. 42 f).   
 Seventh limb: Absent.   
 Furca (Fig. 42 i,j): Each lamella with 4 spinous claws followed by small triangular process fused to lamella. Claws separated from lamella by suture. Small projecting glandular process midway between claws 1 and 2. Long unpaired bristle present posterior to lamellae.   
 Bellonci Organ (Fig. 41 e): Well developed, bifurcate distally, branches taper to point.   
 Upper lip (Fig. 42 a): Anterior margin of body near upper lip with projecting rounded process on each side; anterior tip of lip with chevron-like processes. Lower lip triangular (Fig. 42 k)   
 Gut content: Specimen with 2 food pellets in gut (length 0.19 mm, width 0.11 mm) (Fig. 42 j). Each pellet with numerous closely packed amber-colored narrow strips, a few with nodes suggesting teeth, one terminating in a claw (Fig. 42 l). The strips appear to be the skeleton of one or more invertebrates and indicate that the species is either a carnivore or scavenger.   
 Remarks. The A-4 instar from Norman’s Pond Cave is referred to D. exleyi because 3 other anchialine ostracodes collected in that cave have also been collected in Oven Rock Cave, the type locality of the species. Each cave is on a different cay in the Exumas. This is the first report of the genus in Norman’s Pond Cave. An A-4 instar of the species has not previously been described; the morphology of the present specimen is consistent with what would be expected for an A-4 instar collected at the type locality.
