152. Trachinotus culveri Jitnlou d- SlitrL-K. 



A sinj^le specimen was taken in the market. 



Tliis spooios seems to differ from T. fnlcatnsi in liavini; a slii;iitly sliorter 

 dorsal and anal. Oin Panama speeimen and the type and co-type from INTa/atlan have 

 the following lin connts: Dorsal VI, I, IS; Vi, I, IS; \l, 1, 17; anal 111. IC; III, 

 17; 111, IG. In twelve specimens of 7'. fdlatlns, three have 20 soft rays in the 

 dorsal, nine have 19; in the anal, nine specimens have IH soft rays, three have 

 17. As the largest specimen of falcatus in our" possession is hnt 8 cm. in length, 

 other comparisons are unsatisfactory. 



T. cu/veri differs from 2\ kennedyi in iiaving a dcejicr, more angulated body 

 and in having the mouth more ohli(|ue. The anterior end of the prennaxillary is on 

 a level with a point a little above the lower rim of the orl/it in T. cnlcerl, while it is 

 slightly below the orbit in 7\ kenncdiji. 



153. Trachinotus kennedyi Steindachner. 



Frequently brought to market but never in large numbers. Six specimens 

 were preserved, 28 to ol cm. in length. 



They are smaller than the specimens from which Dr. Steindachner wrote his 

 excellent description, and differ slightly as follows: Head 3J- to '^ in length; depth 

 l|tol|. Eye 4 to 4| in head; interorbital width 21. The maxillary reaches to 

 below the middle of the eye or only slightly beyond that point. 



154. Trachinotus paloma Jordan & Starlcs. 



One adult specimen taken, 31 cm. in length. We have in addition a large 

 specimen from Magdalena Bay and several small ones (including the types), from 5 

 to 10 cm. in length, from Mazatlan and San Juan Lagoon, Mexico. For comparison 

 we have a single large specimen and two smaller ones of 7\ carolinun from the 

 Atlantic. 



2\ paloma differs from 2\ caroUnus in having a smaller eye, 5;^ to 5,V in head 

 in adult, 3^ to A\ in young (4t in carolinus in adult, 3 to 3^ in young). The gill- 

 rakei-s are longer, their length contained 6 times in the postorbital part of the head 

 in the adult (10 times in the adult of carolinus). They number the same in the two 

 species, 4 + 9 or 10. The snout is longer, 3| in head (4 in head in carolinus), and 

 the maxillary is shorter, 3 in head (2',' in carolinus). The anal lobe seems to be 

 shorter, 1| in head, 1) in anal base (in carolinus it equals head and is 11 in base of 

 anal). We find little difference in size of head between the two species, though such 

 was alleged to exist in the original description of 2'. paloina. 



155. Nomeus gronovii {Gmdin). 



Recorded from Panama by Dr. Eigenmann (1894, p. 029), who states that 

 they were taken in " rocky pools at Panama." It has not been taken by other 

 observers.
