to base of caudal. 
Family SPHYRTENIDTE. 
Sphyrsena helleri Jenkins, new species. Fig. 1. 
Head a little greater than 3 in length of body; depth 8.5 in length. 1). v, 10; A. 10. Head long 
and tapering, the snout being long, and 
the lower jaw, which projects beyond 
the upper, terminating in a tapering fleshy 
appendage. Eye 4.5 in head, slightly 
ovate, wider end anterior. Interorbital 
flat, 3.33 in snout, somewhat narrower 
than vertical diameter of eye. The max- 
illary does not reach front of orbit, being 
separated from it by a distance equal to 
about one-fifth of its own length. Scales 
on suborbital not extending forward 
beyond posterior border of eye. Scales 
on cheeks in about 12 vertical series, about 9 vertical rows on opercle, a few scales on subopercle, rest of 
head naked. Opercle without spines. Two teeth in front of lower jaw, about fifteen back of these in 
each ramus. Distance from occiput to first dorsal fin, from first dorsal to second dorsal, from second 
dorsal to last vertebra equal, and each equal to distance from tip of snout to posterior margin of eye. 
Insertion of ventrals below front of first dorsal fin, back of tips of pectorals. Front of anal opposite front 
of second dorsal. (Fin rays all broken in specimen described, pectoral apparently very short, perhaps 
11 in length of body. ) 
Color in life: Upper parts plumbeous, lower parts silvery; top of head and fleshy tip of lower 
jaw blackish; fins plain. 
This species is structurally very similar to Splvyrxna jello Cuvier & Valenciennes, 1 of the Indian
