81. Scorpaena plumieri Bloch. 



82. Scorpagna sp. 



Four iiij mature specimens, representing apparently two species, both 

 distinct from plumieri, are in the collection from Panama and Acajutla. 

 They are too small to permit identification. 



83. Gobiesox adustus Jor. & Gilb. 



Two specimens, in fine condition, are in the collection. They were 

 obtained by Captain Dow on the coast of Central America. The species 

 was hitherto known from Mazatlan only. 



The following ^joints were incorrectly stated in the original descrip- 

 tion: Width of head 2| to 3 in length; pectoral one-third to two-fifths 

 length of head ; distance from base of caudal to front of dorsal, 2f in 

 length of body, 3i in total, including caudal. D. 9 or 10; A. 7 or 8. 



Emblemaria gen. nov. ( Blenniidw.) 



Body slender, not eel-shaped, compressed, scaleless. Ventrals j)resent, 

 jugular, each of oue spine and two soft rays. A single dorsal fin begin- 

 ning on the nape and extending to the caudal, with which it is not con- 

 fluent; no notch between spinous and soft rays. Head cuboid, com- 

 pressed, narrowed anteriorly, with much the aspect of OpisthognatJius. 

 Symphysis of lower jaw forming a very acute angle. A single series of 

 strong, blunt, conical teeth on each jaw, and on vomer and palatines. 

 Vomer and palatine teeth larger, their series continuous parallel to the 

 series in upper jaw\ Xo cirri anywhere. Gill-openings very wide, the 

 membranes broadly united below, free from the isthmus. Lateral line 

 obsolete. 



This genus bears some resemblance to Blennius, but the dentition is 

 entirely different, approaching that of Chcenopsis. 



84. Emblemaria nivipes sp. nov. (29,676). 



Color in spirits: Sides dark brown, with 8 to 10 lighter vertical bars 

 of variable width ; body lighter below^ ; obscure cross-bands on lower side 

 of head. Dorsal blackish anteriorly, whitish behind, with membrane at 

 intervals of every second, third, or fourth ray dusky ; caudal light at base, 

 its tip blackish ; anal dusky-translucent ; ventrals bright white, the basal 

 portion dusky. 



Headof in length; depth 7. D. XXIII, 14; A. 25. Body everywhere 

 equally compressed, posteriorly tapering; head wider than body, of 

 about equal depth, with very short, subvertical, sharply-compressed 

 snout; eyes very large, approximated above, with some vertical range; 

 orbital ridges sharply raised above, the interorbital region very narrow, 

 channeled, about equaling diameter of pupil ; eye 3§ in head. Gape 

 very wide, horizontal, low, reaching much beyond eye, the maxillary 

 about four-sevenths head, not produced beyond angle of mouth ; inter- 

 maxillaries separated by a groove from the snout, this groove continu-
