80 CALIFOKNIA ACADEMY OF SCIENCES 



Depth from 1|- to 2 in length. Eye 4^- to 4f in head; snout 2 J to 3. Pec- 

 toral one-fourth to one-fifth longer than head. Ventrals reaching well past vent, 

 about half the distance from their insertion to the third anal spine. Length of gill- 

 rakers a little over half diameter of eye, their number 6 + 16. In three specimens 

 the dorsal rays number 19 and the anal 17; in three the dorsal is 18 and the anal 16, 

 and in one the dorsal is 19 and the anal 1(). Scales in the straight part of lateral 

 line 48 (not 58). 



146. Alectis ciliaris (Block). 



But few of this species were seen. We have compared our material with a 

 single specimen from Jamaica and can appreciate no differences. 



147. Vomer setipinnis (Mitchill). 



Brought into the market almost daily, sometimes in large numbers. We 

 preserved nine adult specimens and several young; the latter were taken in the 

 tide-pools. 



We have compared our adult specimens with three specimens from Beaufort, 

 N. C, and a single large sjiecimen from Jamaica. From the former, ours differ in the 

 following respects: The body is more slender, the declivity of the anterior profile is 

 less steep, the space between the eye and the angle of profile above eye is shorter, 

 the bases of the anal and soft dorsal are shorter, and the scutes on the caudal 

 peduncle are larger. They differ from the Jamaica specimen only in having larger 

 scutes. We have compared the young with sjiecimens of the same size from 

 Galveston and find them similar. The specimens from Beaufort seem to occupy a 

 position between the Panama specimens and V. s^nx'it. 



Our material from the Atlantic is so meagre that we are unable to decide 

 whether the sjiecies from the Pacific is distinct or not.
