Body not strongly compressed, its depth 5.2-6.5 in SL. Head 3.6-3.7, its depth 

 scarcely equal to its postorbital length. Snout projecting rather more than half of its 

 length beyond mandible, only a little shorter than eye, 5-0-5.3 in head. Eye 4.4-4.8 

 in head, 2.5-2.75 in postorbital length of head. Postorbital part of head long, 1.73- 

 1.77 in head. Maxillary rather narrow, rounded distally, extending beyond orbit a 

 distance equal to about 1.3 diameter of eye, not quite to joint of mandible, 1.5-1.6 in 

 head. Mandible i. 48-1. 53. Cheek nearly as long as snout and eye, its posterior angle 

 about 40°. Gill rakers scarcely as long as eye, broad and close-set, with minute ser- 

 rations on inner edge. 



Dorsal fin with longest rays reaching beyond tip of last ray if deflexed, its origin 

 about equidistant between tip of snout and base of caudal. Anal with origin well behind 

 tips of longest deflexed rays of dorsal, its base 6.5-7.5 in SL. Pelvic inserted about 

 half of diameter of eye in advance of dorsal and nearly equidistant between base of pec- 

 toral and anal origin, reaching rather less than halfway to anal. Pectoral usually failing 

 to reach pelvic by rather more than diameter of eye, 1.9-2.5 in head. Axillary scale 

 of pectoral long, narrow, failing to reach tip of fin by a distance equal to or less than 

 diameter of pupil, 2.3—2.7 in head. 



Color. In alcohol, pale (originally in formalin). Sides of head bright silvery. 

 Lateral band bright silvery, fully as broad as eye. 



Range. This species is known only from the Gulf of Venezuela.

Distinctive Characters. The short maxillary, extending about a pupil's diameter 

 posterior to a vertical at end of eye, the elongate body, with the depth more than 7 

 times in SL, and the very short anal, with 9-1 1 rays and with its origin below that of 

 the last dorsal ray, show that this species is a very distinctive one, if Puyo's descriptions 

 are reliable. 



Description. Based on published accounts and figures by Puyo (see References 

 below). Body very elongate, lightly compressed anteriorly and progressively more 

 rounded posteriorly (in transverse section); depth a little more than 7 times in total 

 body length (SL). Head a little more than 5 times in same; a sort of transverse keel 

 present on superior surface of head. Snout somewhat rounded. Eye equal to snout 

 (pupil shown as abnormally large in most of Puyo's drawings, probably in error). 

 Maxillary rounded at the end, extending about a normal pupil's diameter posterior
