THE VOYAGE OF H.M.S. CHALLENGER. 
s- .n . Bittium mamillanum, n.sp. One specimen (afterwards broken); obtained at no 
other locality. 
C thna tenella, Jeffreys. For distribution see Station 75. 
Fishes (Gunther, Zool. pt. 57). 
M'amphaes crassiceps, n.sp. One specimen; obtained also at Stations 107, 
14G, and 220. 
Gonostoma microdon, n.sp. Twenty-five specimens; for distribution see 
Station 23. 
Bathytroctes rostratus, n.g., n.sp. One specimen ; obtained at no other locality. 
Bathypterois quadrijilis, n.g., n.sp. One specimen (500 fathoms) ; obtained also at 
Station 126, 770 fathoms. 
K< michthys infans , n.sp. One specimen (500 fathoms) ; obtained also at 
Station 101. 
In uddition to the foregoing, the following are recorded in the Station-book : — 
S i tulariuii Archaster , Ophiurids, many specimens of Salenia, worm (?), many 
Schizopoda. 
Excluding Protozoa, about 150 specimens of invertebrates and fishes were 
obtained on this date, belonging to about 58 species, of which 34 are new to science, 
including representatives of 6 new genera ; 15 of the new species were not obtained 
elsewhere. 
Willemocs-Suhm writes: “Besides several Eckinoderms, which have hitherto been 
I >und only in the north, the dredge brought up a Crustacean ( Serolis ), three species of which 
ire known to occur on the coast of Patagonia in shallow water. There is besides a very 
curious red worm, in which no bristles could be found, and which somewhat approaches 
G'fi'ihoglnsuvs in shape. The head and collar are, however, not very distinct, and its 
in ••mid org anisation must differ widely from that of Balanoglossus, for on being put into 
•pint it sent out a long penis. The presence of such an organ in worms indicates a much 
r . t labo rate and distinct arrangement of the genital organs than is found either in 
N rn rt> ms, Annelids, or Balanoglossus. Shrimps came up in considerable quantities, 
i "! them not of great interest, with the exception of a little Schizopod with loose 
‘ • ’ ; this species has been got before, and to-day many males and females were 
1 d Vmong the Peneids there was a very large animal with elevated carapace, 
1 n i ' mto different regions by longitudinal and transverse ridges. There was also 
A' iphip ’d, formerly got on the coast of Nova Scotia, and another somewhat approach - 
1 • Hyp- rimt but apparently blind. Both these forms seem to me to differ widely 
from known types.”
