 rather small.

The scales are well developed; the lateral line is conspicuous and slightly 

 bent downwards upon the abdomen. 



The upper regions are rufous brown; the sides and belly shining silvery. 

 Minute blackish dots are scattered all over, more densely on the dorsal region. 

 A double series of these spots may be traced along the course of the lateral line. 

 Dorsal and caudal fins greyish yellow ; pectorals, ventrals and anal light yel- 

 low.

37. Fundulus PARViPi.NNis, G. Greatest length of specimen observed, three 

 inches and one third; head contained in it a little more than four times. The 

 body is compressed, the back slightly arched anteriorly to the dorsal fin. Great- 

 est depth a little less than the" fifth of the length. Eyes subelliptical, their 

 horizontal diameter contained four times in the length of side of head: once in 

 advance of the anterior rim of the orbit. Anterior margin of dorsal equidistant 

 between tip of snout and posterior margin of caudal, which is subconvex. The 

 origin of anal is opposite the middle of base of dorsal. All the fins are of small 

 dimensions.

Scales rather large ; twelve longitudinal rows may be counted on the line of 

 greatest depth of body. 



Ground color greenish yellow; upper part of head, back and sides blackish, re- 

 sulting from the accumulation of minute dots upon the scales, less crowded on 

 the flanks. Belly and inferior surface of head, unicolor, yellowish. A black 

 stripe exists upon the middle of the flanks, from the anterior third of body to 

 the base of caudal fin.

42. Engraulis delicatissimus, G The fascies of this species is widely dif- 

 ferent from that of either E. eacrasieholvs or E. mordax : the body being more 

 compressed, less tapering, and the head much shorter and less acute. The entire 

 length of the largest specimen before us is about three inches, the head being 

 comprised in it nearly five times and a half. The greatest depth of body is a 

 little less than the length of head, the upper surface of which is convex and but 

 siishtly declive. The eye is large and circular, and its diameter contained 

 twice and three fourths of a time in the lenth of the side of head. The origin 

 of dorsal is nearer the end of snout than to the extremity of caudal fin. The latter 

 is forked. The base of anal is almost twice as long as that of dorsal, and its an- 

 terior margin situated opposite the middle region of the latter. The ventrals 

 are small and short ; the pectorals long and slender.

 The few scales left scattered all over the body are very large. 

 Ground color yellowish; a silvery band, about a tenth of an inch, or slightly 

 more, in width, occupies the middle of the flanks from head to base of caudal.
