FISHES FROM NORTHEASTERN PACIFIC — CHAPMAN 519 



ventral surface from the symphysis, and around the eye, where a row 

 completely encircles that organ. In the lateral series there are 45 

 photophores in the 0-V series and 18 in the V-A series. In the vcd- 

 tral row there are 57 organs in the I-V series and 19 in the V-A series. 

 In the caudal series there are 13 photophores. There are 14 photo- 

 phores in the branchiostegal series, and 13 branchiostegal rays. 



The body is slenderer than that of the larger specimen. It is black 

 along the abdominal region, but not densely jet-black as in the holo- 

 type. The rest of the body and the head are a rich brown. The 

 barbel is 4 mm long, and is completely contained in the depression 

 between the lower jaws. Its base is stout and it tapers to a fine point. 

 It is rather simple, devoid of luminous bulbs or tendrils, and does not 

 appear to have been broken. 



There are only 45 teeth on the lower jaw. These are arranged 

 similarly to those in the holotype except that there are only 9 obhque 

 rows posteriorly and each of these rows contains only 4 or 5 teeth. 

 On the upper jaw there are about 30 teeth arranged like those on the 

 larger specimen. The rows on the "tongue" have 7 teeth in each, 

 the additional pair being inserted upon the basihyals. 



Remarks. — Both of these specimens were taken off the west coast 

 of British Columbia. The depth of their capture indicates that they 

 are probably similar to the other Gymnophotodermi in being confined 

 to a truly bathypelagic habitat. 



Named in reference to the nmnerous photophores in the lateral and 

 ventral series.

Holotype. — A specimen 85 mm without caudal, from station 734B, 

 taken May 10, 1932, latitude 56°55' N., longitude 156°11' W., 

 U.S.N.M. no. 108150, is clearly referable to the genus Sudis but 

 differs from any other species described in that genus.
