till' (iiigin of (loi'sal to snout and from origin of veutrals to snout is a 

 low even rurvc. The interorbital space is slightly and evenly convex. 

 The snout is louiided, its depth at nostril \mng greater tliaii its width. 

 Preorbital is rather wide and unsealed, the anterior margin not notched, 

 its widtli at angle of jaw 1.50 in orbit, its width below middle of eye 

 very little less than its angle. Maxillary ending on a line midway 

 between posterior nostril and anterior' margin of eye. The end of 

 mandible not reaching to oi-hit. Teeth in a single sei'ies in jaws, rather 

 strong, fixed, almost conical, and with a slight curve, 2() on each side of 

 lower jaw. No teeth on vomer or palatine. (4ill openings large, ending 

 on a line slightly anterior to orbit, (xill rakers slender and [)ointed, the 

 longest about e(|ual to pupil. 14 on lower limb. 



Scales covering i-ntiie body and head except the orbital ring, maxillary, 

 and mandibles; the scales are large smooth with their margins finely 

 ctenoid. Kins scaled, except the ventrals ; a high scaly sheath to dorsals 

 and anal. A large axillary scale at ventrals; scales largest on the median 

 anterior part of body: small scales at base of fins and thorax. Six scales 

 between origin of dorsal and head and about 13 series on top of head. 

 Two rows of large scales on the ])reopei'cle with two or three small scales 

 on its lower margin. 



Origin of doi'sal tin about the width of eye posterioi- to pectoral axil, 

 the first spine being midway between tip of snout and origin of twelftli 

 dorsal spine, the spines gradually increase in length posteriorly, the first 

 spine being 1.30 in eye while the last 2 in head (measured to base of 

 scaly sheath). Soft doi'sal rounded, its longest I'ay 1.25 in head. The 

 anal is similar in shape to soft dorsal, its second spine is 2 in head, the 

 longest ray is about equal to longest ray of soft, dorsal ; origin of second 

 anal spine on a line with base of 13th doi'sal spine, being midway between 

 end of caudal vertebra and origin of ventrals, the first anal spine is quite 

 a- little in advance of the second. Origin of ventrals midway between 

 first anal spine and tip of snout ; ventrals are slightly filamentous at tip 

 but do not quite reach to anal pore. Pectorals are rounded, the width 

 of their base being "3.50 in their length. Caudal rounded, scarcely 

 emarginate. the upper lobe the longer, being about equal to length of 

 head. 



Colo)' in life uniform dark brown or blackish. 



Color in alcohol olivaceous black, fins black, operodai' Ha|) black. A 

 black dot at axil of pectorals. Xo ocelli anywhere. 



Type is No. 4908. A specimen 123 millinietei's in length taken by
