56 DEEP SEA FISHES. 
comparisons it was found that not so many of the species from the western 
Pacific were identical with others in the Mediterranean and the eastern 
Atlantic as has been supposed, and this has led to doubts of a number of 
which only descriptions are available with which to compare. In general 
it may be said that the affinities of the species in the collection, from the 
region about the Galapagos, are closer to those of the western Atlantic than 
to those of the western Pacific. In case of Caulolepis the species from the 
eastern Pacific is so nearly allied to that from the western Atlantic that 
they can hardly be separated by the characters ordinarily used in specific 
diagnoses. 
Species of Melamphaés and of Stephanoberyx have been taken in the 
north Atlantic, Lat. 37° N., Lon. 73° W., at a depth of 2949 fathoms, the 
deepest as yet reported for the group. Species of Melamphaés have also 
been taken at 1998 fathoms off the Cape Verde Isles, at 2232 fathoms off 
the Galapagos, at 1575 fathoms in the southern part of the Indian Ocean, 
and at 1805 fathoms in the Bay of Bengal. Malacosarcus was secured at a 
depth of 2550 fathoms near the Low Archipelago in the Pacific. When 
properly completed a list of the species of this group belonging to a depth 
of 150 fathoms or more will no doubt include nearly or quite all of the 
family; at present a considerable number have no definite depths assigned 
to them.

This species differs little from either Hoplostethus mediterraneus C. V. or 
HT. japonicus Hilg. in general outlines; in many respects it agrees with them 
very closely, but it may readily be distinguished by less development in the 
anterior portion of the dorsal fin, by a greater development of the pectorals, 
and by a larger number of scales in the median series on the abdomen, 
Form much compressed, tapering rather abruptly backward of the body 
eavity, depth five elevenths of the length to the base of the caudal or five 
fourteenths of the entire length, little more than the length of the head.
