ON THE IDENTITY OF THE GENUS LEURYNNIS, LOCKINGTON, 
WITH LYCODOPSIS, COLLETT. 
By THEODORE GILL. 
In the Proceedings of the Zoological Society of London for 1879 
(at pp. 380-3381) Mr. Robert Collett has published a communication “On 
a fish of the genus Lycodes from the Pacific.” The article was read at 
the meeting held April 1, 1879, and published in the part (II) issued 
August 1, 1879. 
In this article Mr. Collett describes at length the species referred to, 
under the name Lycodes pacificus, and gives a figure of the head and 
anterior part of the body. The diagnosis is as follows: 
‘““Vomerine and palatine teeth none. Coloration uniform yellowish 
grey. The body is scaly, the head and pectorals naked. The head is 
contained four and six-tenths, the height of the body nine times, in the 
total length. Lateral line very indistinét.

“ Hab.—Japan (Mus. Berol.).” 
At the end of the description Mr. Collett expresses the following 
opinion: 
‘The absence of vomerine and palatine teeth, a character quite peculiar 
to the species, will perhaps necessitate its removal to a separate genus, 
for which I propose the name Lycodopsis.” 
In the Proceedings of the United States National Museum for 1879 
(at pp. 326-332) Mr. W. N. Lockington has given ‘“ Descriptions of new 
genera and species of fishes from the coast of California.” The signature 
in which it appears was issued March 25, 1880. 
In this article Mr. Lockington describes what is considered to be a 
new generic type, under the name Leurynnis paucidens. The diagnosis 
of the genus is as follows: 
“Generic characters—Family Zoarcida, allied to Lycodes. Ventral 
fins present, short; no teeth on vomer and palatines; dorsal and anal 
fins continued without interruption around the tail; scales small, but 
evident. The name is from Aevpds—smooth; y».s—vomer, in allusion to 
the character which chiefly distinguishes the genus from Lycodes.” 
Selecting characters to compare with those mentioned in Mr. Collett’s 
diagnosis, we have the following: 
“No vomerine or palatine teeth.—Color olivaceous, the scales lighter 
than the skin; the color formed by numerous dark points, which are 
continued also upon the head. Upper surface of head darker, abdom- 
inal surface lighter than other portions. Vertical fins margined with 
black.—Seales roundish, smooth, separate, imbedded in the skin, uniform 
over the whole of the body, except upon an area on the upper surface in 
front of the dorsal, where they are smaller, and region near base of 
pectorals scaleless. Head scaleless—the ridges somewhat prominent.—
