135. Trachurops crumenopthalmus (liluch). 



Occasionally brought to market, where numerous speciraen.s were collected. 

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

 specimens from the Atlantic and the Pacific. 



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

 toral from 3[ to 3|. Orbit 21 to 3' 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 it 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 2J to 2J; length of pectoral 21 to 2-,'; chord 

 of curve of lateral line 3.V to 4; straight part of lateral Hue l^ to 2. Orbit 3J to 4J
