ADDITIONS TO FAUNA OF SAN DIEGO. 5 



an additional one just above the fourth pair on the breast 

 (some of those on shoulder probably obliterated) ; no 

 white blotches or spines about caudal peduncle. 

 Black, scales strikingly coerulescent; fins light. 



Stenobrachius subg. nov. 



Type, Alyctophmn Icncopsanini sp. nov. 



The comparatively small e3'e and enlarged scales of 

 the lateral line would place this species in the genus 

 Alysia Low. It does not appear to us that the differ- 

 ences are of sufficient importance to warrant more than 

 a subgeneric separation from MyctopJnim. As the name 

 Alysia is preoccupied, and we are not able to examine 

 specimens of the type oi Alysia, wo. propose Stenobrachius 

 as a subgeneric or generic name for this species, in allu- 

 sion to the very narrow pectorals.
