ADDITIONS TO FAUNA OF SAN DIEGO. 3 



inserted slightly anterior to the dorsal tin, their tips reach- 

 ing the vent, not to anal. Pectoral fins i}4—^/i in head, 

 not nearly reaching the ventrals. 



Upper teeth strongly hooked, the lower more conical; 

 the tips of all the teeth black in fresh specimens. 



Peritoneum black; intestinal tract little longer than the 

 total length. 



A conspicuous plumbeus lateral band nearly as wide 

 as depth of eye extending from shoulder to base of cau- 

 dal; a triangular blackish spot on base of caudal; top of 

 head and back downward to lateral band dark gray; ven- 

 tral surface below lateral band pinkish in life ; sides and 

 middle of head with black dots ; caudal smutty, other fins 

 plain. 



SCOPELID^. 



The members of this family seem to be quite abund- 

 ant. They descend to deep water in stormy weather, 

 and are then eaten in quantity by the rock-cods, from 

 whose mouths all the members so far known from this 

 region were taken. They are more restricted in their 

 habitat than might be expected. None of the species 

 taken within twenty miles of Point Loma, with one 

 doubtful exception, were found on Cortes Banks, and the 

 three species collected on those banks have not, as yet, 

 been taken near Point Loma. 



DiAPHUS gen. nov. 



Type: Diapliiis theta sp. nov. 



Characters of Myctoplmin; phosphorescent spots di- 

 vided into halves by a median black line. 



The phosphorescent spots being very important charac- 

 ters in the family ScopelidcB, their peculiar modification in 

 the species described below seemed to us to be of gen- 

 eric value.
