THE VOYAGE OF H.M.S. CHALLENGER. 
Stations 194 
and 194a. 
Gasteropoda (Watson, Zooi. pt. 42). 
Murex ( Haustellum ) sp. (?). One specimen (200 fathoms). 
Cephalopoda (Hoyle, Zool. pt. 44). 
Spirilla peronii, Lamarck. One specimen (360 fathoms) ; shells obtained also at 
the surface in North Atlantic, Raine Island, and off New Guinea. 
* 
Brachiopoda (Davidson, Zool. pt. 1). 
Distinct atlantica, King. (200 to 360 fathoms) ; obtained also at Stations 106, 237, 
246, 271, and 300. 
Fishes (Giinther, Zool. pts. 6 and 57). 
Peristethus murra yi, n.sp. One specimen (200 fathoms); obtained at no other locality. 
Recorded subsequently from Indian Ocean (“ Investigator”). 
Ceratias bispinosus, n.sp. One specimen (360 fathoms); obtained at no other locality. 
Gonost&ma elongatum, n.sp. One specimen (360 fathoms) ; obtained also at 
Station 191. 
In addition to the foregoing, the following are recorded in the Station-book : — Five 
specimens of an Ophiurid with conical body, two Holothurians, Aphroditaceans in Sponge, 
two specimens of Alpheus in Sponge, and a Macrurid fish. 
Excluding Protozoa, over 50 specimens of invertebrates and fishes were obtained 
at these Stations, belonging to about 39 species, of which 24 are new to science, 
including representatives of 5 new genera; 16 of the new species and 3 new genera 
were not obtained elsewhere. 
The trawl brought up a specimen of the long-sought Spirilla animal. It showed 
no signs of life, and some of the naturalists thought it might have been dead before 
capture by the trawl. Adams described the genus and enumerated all the specimens 
hitherto obtained. Owen obtained the specimen upon which he founded the species 
Lituus reticulatns from the Sulu Sea (Ii.M.S. “ SamaraDg ”). Our animal, taken near 
that locality, has been described by Professor Huxley as Spirula peroni , 1 Lamarck. 
It is probable that Spirula swims and creeps along the bottom in deep water, 
adhering to stones and hiding in holes when anything like a trawl or dredge comes 
to disturb it. Only on this hypothesis can the scarcity of the animal be accounted for ; 
it has never been taken in the Moluccas, where the natives have orders to look out 
for it, and at Ca|>c York and Fiji the natives declare that the shell Ijas no animal at all.
