The deep-sea Crustacea dredged by the Investigator, and named,
up to the end of the year 1897, number 188 species ; but only the stalk-eyed
forms have been fully worked out.
In addition to these 188 species, several other extremely interesting
forms have this year been dredged, but are not included in the list, as no notice
of them has yet been published ; among them are a new species of Spongicola
from 498 fathoms, species of Pylocheles from 185 fathoms, of Ptychogaster,
Paralomis, Trachycarcinus and Homalodromia from 430 fathoms.
Of the 188 species mentioned in the following list, 124, excluding all
about which there is any doubt, are new to science, and among the new species
eighteen are types of new genera ; these are marked with an asterisk in the list.
Although these 188 species all belong to the deep-sea fauna, there is no
doubt that a good many of them live, not at the bottom, but at middle
depths, This question has already been discussed by other writers, notably by
Faxon, in his recent memoir of the Albatross Crustacea, so that I shall here
relate only my own observations and conclusions. There can, of course, be
no doubt that the creeping forms, such as the Brachyura and Anomura,
must come from the bottom. We are also justified in assuming, from their
colour, from the several modifications (in the directions either of hypertrophy
or of atrophy) of their organs of vision, from the very moderate development of
their swimming-feet, and from the habits of their shallow-water relatives, that
the species of Phoberus, Nephrops, Nephropsis, Iconaxius, Calastacus, Calocaris,
Callianassa, Polycheles, Panulirus, Arctus, E ngystenopus, Alpheus, Crangon,
Glyphocrangon, etc., inhabit the bottom. But it is probable that most of the
Schizopoda and of the Peneiform Macrura, as well as forms like Heterocarpus,
Pandalus, Hoplophorus, Acanthephyra, Pasiphæa, Psathyrocaris, Nemato-
carcinus, etc., swim freely at varying depths beneath the surface.
On one occasion when the dredging-rope fouled, and the trawl, though it
may have touched the bottom in 1,439 fathoms, clearly could not have dragged,
for it came up almost clean, we found in the bag only a Willemoesia, a
Dorodotes, and an Hoplophorus.
On two other occasions, when the trawl was lowered in 840 and 922 fathoms,
but certainly did not touch bottom, the bag contained (besides a Medusa, a
Chiroteuthis pellucida, and a Chauliodus fish) two species of Gnathophausia,
a Sergestes, an Acanthephyra and a Phye. All these Crustacea, although (with
the probable exception of Willemoesia) they almost certainly did not come
from the bottom, yet must undoubtedly—if their colour and the texture of their
tissues, as well as the fact that they were dead on reaching the surface, are
criteria—have lived at a considerable depth. In the case of Hoplophorus,
however, even this is doubtful, for both Dr. Anderson and myself have noticed
it alive and active, though giddy, after reaching the surface,

The geographical distribution of the 60 previously-known species on our
list, now newly met with in Indian waters, is in several cases most curious
and suggestive. Twenty-seven of them are Challenger species from the
East Indian Archipelago and Japan, and would be expected to occur in Indian
waters. Seven (namely Gnathophausia zoœa, Eucopia australis, Bentheu-
phausia amblyops, Aristeus armatus, Gennadas parvus, and Acanthephyra
brachytelsonis and microphthalma ) are free-swimming forms that were already
known to have a most extended range ; and one ( Parapagurus pilosimanus ) is
a true abyssal form of world-wide distribution ; so that their discovery in Indian
Seas is not remarkable. Four (Eucopia scuipticauda, Thysanopoda obtusifrons,
Acanthephyra cristata, and Munidopsis trifida ) are Pacific species of which two
were known only from the coast of Central America, and one only from the
Patagonian fjords. Fourteen are free-swimming Atlantic species, mostly known
from the Albatross dredgings, and though their occurrence in Indian waters
is interesting, it is not difficult to understand.
The chief interest attaches to certain forms which, though not all truly
abyssal, and neither pelagic nor free-swimming, are known to occur, outside
Indian waters, only in the Gulf of Mexico, the Carribbean Sea and the neigh-
bouring Atlantic depths. These are (1) the very remarkable Isopod, Bathy-
nomus giganteus, (2) the blind lobster, Phoberus caecus, (3) Willemoesia forceps,
(4) the remarkable hermit-crab, *Pylocheles agassizii, (5) Uroptychus nitidus,
(6) Lithodes agassizii. Hardly less interesting is the occurrence in the Indian
area (1) of the Faroe (North Atlantic) species Nephropsis atlantica, (2) of the
Mediterranean and British form Pasiphæa sivado, and (3) of the British, Scandi-
navian, North Atlantic and New Zealand form Calocaris macandreæ .
When, along with all these, we consider the distribution of the corals Flabellum
lacmiatum and Caryophyllia communis and of certam fishes of the moderate
depths, we shall wonder whether these facts do not lend some support to the
theory of a Miocene Mediterranean Sea that extended from the Carribbean Sea
eastwards, even beyond the present limits of the Mediterranean basin.

The only named Pycnogonida that have been dredged from the depths by
the Investigator are Colossendeis gigas Hoek, and Colossendeis leptorhyn-

The first Colossendeis, which came from 922 fathoms off the east coast of
the Andamans, was alive when brought on board, and was noticed to be highly
luminous along the ventral surface of the body and of all the legs except the
ovigerous pair ; it spanned over eighteen inches.
