This species is closely allied to //. chromis and H. canna, differing from both by itsmuch shorter and more convex snout. The height of the body is contained twice andtwo-thirds in the total length (without caudal),the length of the head thrice and snout is short, not much longer than thediameter of the eye, which is more than one-fourth of the length of the head. Cleft of themouth rather wide, the maxillary extendingbeyond the vertical from the front margin ofthe eye. Hind margin of the praeoperculumslightly emarginate, its angle with more con-spicuous denticulations. Dorsal fin notched, ^^ ^ with strong spines; the fourth is the longest, ((w ^ ^ half as long as the head. Caudal fin DR. GtJNTHBR ON THE FISHES OF CENTRAL AMERICA. 419 The second anal spine is strong, and somewhat longer than the tliird, hut not quite aslong as the fourth of the dorsal fin. Scales above the pectoral fin not conspicuouslylarger than the others. More or less conspicuous oblique brown streaks run along theseries of scales, and are broken up into series of spots in larger examples. A verticalblack spot covered by the angle of tlie procoperculum. We possess four examples of this species : three were collected by (apt. Dow atPanama; and the fourth is from Puerto CabcUo. The largest is 8 inches long. 35. H^MULOX MARGARITIFERUM. (PI. LXV. fig. 2.)Ouiith. Proc. Zool. Soc. 1864, p. 147. D. jl A. l\. L. lat. 55. I-. transv. 6 15.
