FISHES FROM NORTHEASTERN PACIFIC— CHAPMAN 517 



smaller specimen, is here reduced to a small spot. Above the latter 

 on the anterodorsal margin of the eye, is a third small luminescent spot 

 of crescentic shape. Scattered over the body and head are a myriad 

 of small glandular bodies. Between each pair of branchiostegal rays 

 is a photophore of the same type as those in the lateral and ventral 

 rows. The two rows of photophores along the lower half of the body, 

 typical of the fishes of this relationship, are present here. In the 

 lateral series there are 46 photophores between the operculum and the 

 base of the ventral fin (0-V) and 20 between the base of the ventral 

 and the beginning of the caudal series (V-A). In the ventral series 

 there are 57 photophores between the isthmus and the base of the

ventral (I-VO) and 21 between the base of the ventral and the be- 

 ginning of the caudal series (V-A). 



Because of loss of skin, the caudal series can not be counted accu- 

 rately on the large specimen. 



In the lower jaw there are about 85 teeth varying in size from 

 minute denticles to moderate-sized fangs. Near the symphysis 

 there are 2 teeth, behind these a group of 3 teeth, and posterior to 

 this there is a patch of 4 teeth. Posterior to this last group, and 

 separated from it by a short interspace, the remaining teeth are 

 arranged in 11 oblique, parallel rows, which have 5 to 7 teeth in each. 

 The teeth on the anteroexternal end of the rows are minute denticles. 

 The others graduate in size to the large fangs on the posterointerior 

 end of the row. The teeth in the rows become smaller toward the 

 corner of the jaw. In the upper jaw there are 21 teeth of assorted 

 sizes. Eight of these are on the palatine, 4 on the premaxillary, and 

 the remaining 9 are arranged in 3 oblique rows on the maxillary. 

 There are no teeth on the vomer. The teeth on the two palatines are 

 separated by a median bare space anteriorly. The 4 teeth on the 

 premaxillary are stout and recurved, differing from all the other large 

 teeth in the mouth by not being depressible. They are up on the side 

 of the jaw and do not enter into the gape. There are two rows of 

 large depressible fangs on the "tongue," each consisting of 6 teeth. 

 The first three pairs are based on the glossohyal and are separated by 

 a small interspace from the last three pairs, which are apparently borne 

 by the first basibranchial. The mouth is noticeably curved upward,
