description: 5. Rhinolophus celebensis, sp. n. (Plate fig. 4 <i>a, b</i>.) <i>Rhinolophus megaphyllus</i> (partim), Dobson, Cat. Chir. Brit. Mus. (1878) <i>Diagnosis.</i> Supraorbital crests meeting at a point more or less in front of the middle of the orbit. Nasal swellings narrow. Nose-leaves as in <i>Rh. nanus</i> and <i>Rh. borneensis.</i> Small: forearm 43 *7 mm. <i>Details.</i> In the foregoing species <i>(Rh. simpleX, megaphyllus,</i> truncatus, <i>nanus'),</i> all of which are Australian or Austro-Malayan, the supraorbital crests join the sagittal crest at a point more or less <i>behind</i> the middle of the orbit. In <i>Rh. celebensis,</i> as in all the other species of the present group, which are all Oriental, Palaearctic, or Ethiopian, the supraorbital crests meet at a point <i>imore</i> or less <i>in front</i> of the middle of the orbit. This makes a comparatively shorter postnasal depression, the supraorbital crests being the lateral borders of this depression. In this point therefore <i>Rh. celebensis</i> agrees with the <i>Western</i> forms of the group, differing from the Eastern. The mechanical reason for this modification is evidently the following: a slight increase in the size of the temporal muscle has pushed the sagittal crest more forwards; this involves a shortening of the supraorbital crests; this again a reduction in the length of the postnasal depression. 'Ehe nasal swellings are narrow (*8 mm.), as in the closely related Eastern forms <i>(nanus,</i> truncatus <i>).</i> In the more Western <i>Rh. borneensis</i> they are, at least somewhat, and as a rule considerably, broader. Compare figs. 4 and 5 on Pl. III. It is worth noticing that the cranial characters of this species are, so to say, <i>“</i> in accordance with <i>”</i> its geographical habitat: Celebes is, geographically, intermediate between the Austro- Malayan and Indo-Malayan subregions, and in its more important cranial characters <i>Rh. celebensis</i> points partly westwards (shortening of supraorbital crests), partly eastwards (narrow nasal swellings). 1 The nose-leaves, ears, wings, and the general size are as in <i>Rh. nanus</i> and <i>Rh. borneensis.</i> <i>Colour.</i> (1) Makassar specimen (&amp;female; ad.; in alcohol; unfaded; teeth unworn).—General impression of upper side: brown; the true colour is a deep brown shade of “ drab <i>”</i>; base of hairs a little lighter than drab; under side drab with a tinge of “broccolibrown. <i>”</i> (2) Menado specimens (two skins; ad.; teeth almost unworn).—Above uniform dull “ mars-brown, <i>”</i> base of hairs but slightly lighter; colour of the fur of the under side very much as on the tipper side. The Makassar specimen seems to represent the true “dark phase <i>”</i>; the mars-brown tinge of the Menado skins may indicate a tendency towards a <i>“</i> russet phase. <i>”</i> Similar differences in colour are very common in this section of the group. <i>Dentition.</i> As in <i>Rh. nanus.</i> <i>Measurements.</i> Below. <i>Type.</i> &amp;female; ad. (in alcohol). Makassar, S. Celebes, 1895. Collected by A. Everett, <b>Esq</b>. Brit. Mus. no. 97.1.3.19. <i>Distribution.</i> Celebes: Makassar, Menado.
