135. Trachurops crumenopthalmus (Block). 



Occasionally brought to market, where numerous specimens were collected. 

 It was also observed at Acapulco. We are unable to find any differences between 

 specimens fi'om the Atlantic and the Pacific. 



The head varies from 3J to 3.^ in length; the depth from 3| to 3|; the pec- 

 toral from 3i to 3|. Orbit 2f to 3J in head; maxillary 2]- to 2|; ventral 2 to 2]. 

 Plates and scales along the entire lateral line vary from 86 to 91. 



136. Hemicaranx atrimanus (Jordan & Gilbert). 



Of frequent occurrence in the Panama market, where it appeared sometimes 

 in considerable numbers. 



As the original description was taken from a single specimen, we append the 

 following notes giving a wider range of variation. 



Head 3| to 4| in length; depth 2| to 2|; length of pectoral 2^ to 2J; chord 

 of curve of lateral line 3| to 4; straight part of lateral line If- to 2. Orbit 85 to 4^
