fin long, reacLing to or slightly beyond front of anal, somewhat louger 

 than head. 



Body covered with rather small cycloid scales ; head naked ; the scales 

 are very readily deciduous ; as they have in our specimeus mostly fallen 

 off, the count cannot be given. 



Two specimens, the largest 1^ inches long (No. 29674, U. S. Kat. Mus.), 

 were taken in muddy tide-pools in Charleston Harbor. The species has 

 thus mnch the habit of its congener, G. emhlcmaUcus, from Panama. 



100. Gobionellus oceanicus (Pallas) J. & G. 



GoUus Janceolatus Bloch., Fische Deutscb. II, 12, pi. 38, 17S4. 



fWrohius lanceolalus C. & V., XII, 114. 



Gobionellus kastntiis Grd., U. S. Mex. Bonn. Surv. 18r)9,24. 



A single specimen, 11 inches long, was taken in the harbor. 



Color in spirits, reddish olive ; a distinct, round, blackish blotch below 

 spinous dorsal, twice as large as orbit; an indistict dusky shade along 

 middle of sides, terminating in a distinct dusky blotch on base of caudal ; 

 middle of sides with a series of < -shaped marks, formed by very narrow 

 veiny lines widely diverging backwajds ; a similar narrow^ line from eye 

 to maxillary, and one from eye backwards to upper angle of preopercle ; 

 evident traces of the emerald spot at base of tongue ; two small dark 

 spots on first dorsal spine; spinous dorsal dusky, with a light and a dusky 

 streak at base; soft dorsal dusky, a light (fblnish in life) area behind 

 each ray ; anterior rnys barred with light and tlark ; anal and ventrals 

 whitish (probably blue in life), the ventrals with ont dark markings; 

 pectorals dusky, the base lighter, and with some indistinct dusky bars ; 

 a dusky half-bar on npper part of axil. 



Head 6 in length (Si in total) ; depth Si. Eye 5 in head ; ventrals= 

 pectorals=head; D. VI— 14; A. 1, 14. 



Upper part of opercle with a broad patch of abont 20 scales, arranged 

 in 4 series ; head otherwise naked. Scales on body very small, becom- 

 ing much larger behind ; arranged in 80 cross-series. 



All the dorsal spines more or less filamentous. Caudal fin nearly 

 one-third total length. 



There is apparently another species very closely related to oceanicus, 

 and occurring with it in the West Indies. This is represented in our 

 collection by a specimen from Colon, U. S. C, and appears to be char- 

 acterized by a longer head (a in length, 7 in total), by the much larger 

 scales (CO in lateral line), by the obsolescence of the patch of scales 

 on opercles, and by different coloration. GoUus lanceoJafus C. & V. and 

 Gohionellus lanceolatus, Poey, Syn, Pise. Cub., 393, seem to refer to this 

 latter species. 



101. Gobiosoma bosci (LaC.) J. & G. 



Very abundant along the mnddy shores of lagoons, hiding in oyster- 

 shells and holes in the mud.
