152. Trachinotus culveri Jordan <& Starks. 



A single specimen was taken in the market. 



This species seems to diflfer from T. falcatus in having a slightly shorter 

 dorsal and anal. Our Panama specimen and the type and co-type from Mazatlan have 

 the following fin counts: Dorsal VI, I, 18; VI, I, 18; VI, I, 17; anal III, 16; III, 

 17; III, 16. In twelve specimens of 1\ falcatus, three have 20 soft rays in the 

 dorsal, nine have 19; in the anal, nine specimens have 18 soft rays, three have 

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

 other comparisons are unsatisfactory. 



T. culveri differs from T. kennedyi in having a deeper, more angulated body 

 and in having the mouth more oblique. The anterior end of the premaxillary is on 

 a level with a point a little above the lower rim of the orbit in T. culveri, while it is 

 slightly below the orbit in 1\ kennedyi. 



153. Trachinotus kennedyi Steindachner . 



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

 were preserved, 28 to 31 cm. in length. 



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

 excellent description, and differ slightly as follows: Head 3| to o^ in length; depth 

 1| to 1^. Eye 4 to 4| in head; interorbital width 24. The maxillary reaches to 

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



154. Trachinotus paloma Jordan <t Starks. 



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 sjiecimen and two smaller ones of 2\ carolinus from the 

 Atlantic. 



T. paloma differs from 2\ carolinns m having a smaller eye, 5| to 5|- in head 

 in adult, 3^ to 4J in young (4| in carolinus in adult, 3 to 31 in young). The gill- 

 rakers are longer, their length contained G times in the postorbital part of the head 

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

 species, 4 + 9 or 10. The snout is longer, 34 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, \\ in head, 1| in anal base (in carolinus it equals head and is l-i 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\ jMlovia. 



155. Nomeus gronovii {Gmelin). 



Recorded from Panama by Dr. Eigenmann (1894, p. 629), who states that 

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

 observers.
