53. TRACHINOTUS PALOMA Jordan and Starks. 



A specimen from Callao, 2HT nun. in length without caudal, has a 

 smaller q\q (f)^ in head) than a specimen from Panama, but is not oth- 

 erwise essentially different. 



In comparing this species with T. cdroltna, specimens of nearly the 

 same size should be selected. In the original description of this 

 species the head was alleged to be larger than in T. Carolina. 

 Gilbert and Starks in comparing specimens of alujut the same size 

 found no difference in this respect, though the species was found to 

 b(> well distinguished ))y other characters." In comparing the speci- 

 men at liand with a large specimen of T. Carolina, o-to nun. in length 

 without caudal, tiie head is shorter, being 4| in length in T. jjaloma.^ 

 and 3if in T. carolbaj.
