pale. The form of this species resembles that of Eucinostomus californi- 

 ensis, but the body is always less elongate than in the latter. The form of 

 its premaxillary groove, differing from that of any other species, affords 

 the best character for distinction. Carolina to Brazil, the young ranging 

 nortli to Woods Hole; excessively common everywhere in shallow water 

 and on sandy shores, as is its congener californiensis in the Pacific. It 

 reaches a length of 4 or 5 inches, and is used only for bait. The only spe- 

 cies ranging far northward, {gula, throat; from the common name Petite 

 guenle at Martiui(|ue.)

This genus is close to Eucinostomus, from which it differs in the form of 

 the second interha-mal, which is short, bluntish, and not hollowed out. 

 The single known species is slender in form, with weak spines, the anal 

 fin having but 2. (ouAos; entire; al'/ua, blood, for iiiteih;emal, the 

 interhaimal being entire and not cup-shaped at its upper end.) 



1748. UL.EMA LEFROYI (Goode). 



Head 3A to 31; depth .3f; eye large, 2| in head; snout 3i; interorbital 

 width 3; scales 5-47-9. D. IX, 10. A. II, 8. Body elongate, elliptical, not 

 very strongly compressed ; back little elevated; snout conical, not much 

 pointed; mouth small, end of maxillary reaching scarcely beyond vertical 

 from anterior margin of orbit, its length 3 in length of head, exposed por- 

 tion nearly triangular, its greatest width 2 in its length, which is 5 in 

 length of head; top of head flattish; premaxillary groove long, linear and 

 naked; gill rakers weak, small, 7 or 8 below the angle; dorsal spines all 

 weak and flexible, second and third subequal, | in length of head, upper 

 margin of the tin concave; second anal spine moderate, its length 4 in 

 head; least depth of caudal peduncle 3f in length of head. Color silvery, 

 darker above, everywhere with line dusky punctulations and traces of 

 cross bars; top of spinous dorsal black; dorsal, anal, and caudal dusky; 

 ventrals and pectorals paler, but with dusky punctulations; axil dusky; 

 a dark spot on supraorbital; snout dusky; no distinct stripes along rows 

 of scales. Length 2 to 8 inches. Well distinguished from Eucinostomus 

 pseudof/ula and other related species by the presence of but 2 anal spines, 

 a character which reappears in the very different species, Gerres rhombeus. 

 A much more marked character, however, is found in the small, solid in- 

 terhajmal, which is wholly unlike that of Eucinostomus. West Indies, on 

 sand^ shores, north to Cedar Keys; known from the Bermudas, Cuba, Key
