Jordafi a?id Evermann. — Fishes of North America. 2673 



specimeus (11373) from Rio Janeiro belong to the same species. Amonf 

 these are males, which have the interorbital space much broader than in 

 the types of oceJlatKS and (vfhalion. Besides these specimeus we have 

 examined others from Hayti, Cuba, and Key West, and there can be no 

 reasonable doubt of their identity, aud that all are identical •with Giiuther's 

 Hemirhomhus armnaca. This fish is described and fairly well figured by 

 Rauzani under the name of Stjacium micrurum. It is the type of his genus 

 Si/acium, a generic name which, strangely enough, has received no notice 

 from subsequent authors until lately. (jiiiMpo?, small; ovpd, tail.)

Head 4; depth 2i. D.92; A. 72; scales 60. Body elliptical, the dorsal 

 and ventral outlines equally arched ; mouth placed low, below axis of 

 body; snout with an abrupt constriction in front of upper orbit, the out- 

 line then again convex; eyes on left side, distant, the lower in advance of 

 the upper; a vertical line from anterior margin of upper orbit passing 

 through middle of lower; distance of upper eye from dorsal outline equal- 

 ing I its vertical diameter; interorbital space concave, very wide, its 

 width li times diameter of orbit in a specimen 8 inches long, much 

 narrower in the young; a ridge from upper angle in lower eye runs 

 upward and backward to join a ridge from upper orliit. Nostrils on a 

 level with upper margin of lower eye, the anterior with a flap, distant 

 from the posterior, Avhich is circular; h^ngth of snout to front of lower 

 eye 4nL to 5 in head; mouth very oblique, the gape convex upward and 

 backward; maxillary f length of head, reaching to middle of lower pupil, 

 very narrow and covered with small scales; teeth small, the upper 

 jaw with 2 series, the front teeth of the outer series somewhat enlarged; 

 lower jaw with a single series; vomer and palatines toothless; gill rakers 

 short and broad, the longest about ^ vertical diameter of pupil; about 7 

 on anterior limb of arch; pseudobranchia- present; jtreopercle with pos- 

 terior margin nearly vertical, only the loAver third free, the upi)er | grown 

 fast to opercle and scaled over; the lower margin running very obliquely 

 downward and forward, the angle thus an obtuse one; dorsal fin com- 

 mencing on the snout in front of tipper eye, the first 4 or 5 rays exserted 

 and turned over to the blind side; the highest rays are behind the middle 

 of the fin and are about | length of head; anal fin similar to dorsal, its 

 origin under base of pectorals; caudal short, about | length of head, the 

 middle rays the longest, the outer rays slightly prolonged ; ventrals un-
