than dorsal ; pectorals reaching ventrals, which reach halfway to seventh 

 anal ray. Coroiiado Islands, near San Diego ; one specimen from stomach 

 of Sehastodm miniatus. (Eigenmanu.) Very close to T. crcnularia, hut 

 the belly kvss arched, the anal spots fewer, and the ventrals slightly 

 longer ; probably identical with the latter.
