1161. MENIDIA PENINSULA (Goode & Bean). 



Head 4 ; depth 5 ; eye 3 to 3|, about equal to snout or interorbital 

 width. D. IV or V-I, 8 or 9; A. I, 15 to 18; scales 38 to 40-9. 

 Mouth very protractile ; lower jaw long, more than length of head. 

 Scales large, thin, and smooth, with entire edges. Soft fins scaleless. 

 Origin of spinous dorsal in advance of anal fin, midway between tip of 

 snout and upper base of caudal. Light green ; edges of scales with dark 

 dots ; lips and top of head dusky ; a dusky streak along base of anal ; 

 eye silvery ; lateral streak narrow, tapering behind ; bases of pectoral 

 and caudal bright yellow ; fins otherwise nearly plain. Length 4 inches. 

 Florida and Gulf Coast, very abundant in schools along the sandy 

 beaches. Specimens from black water are very dark, the silvery band 

 underlaid by black, (peninsula, of the peninsula, i. e., Florida.)

1162. MENIDIA GRACILIS (GUnther). 



D. IV-I, 8 ; A. I, 19 ; scales 40-9. The origin of the anterior dorsal fin 

 is opposite the vent, exactly in the middle of the distance between end 

 of snout and base of caudal. The distance between the origins of the 

 two dorsal fins is somewhat more than | that between the origin of the 

 posterior and the caudal. The height of the body is contained nine 

 times in the total length, the length of the head five times and a half. 

 The silvery band is narrow, and occupies a portion of the fourth series 

 of scales. Scales with the margin entire. Caudal lobes equal in length; 

 caudal somewhat longer than the pectoral, and rather shorter than the 

 head. Original locality unknown. (Giinther.) 



We refer to this species a number of specimens collected by Dr. Hugh 

 M. Smith on St. George's Island, Lower Potomac. These specimens are 

 identified by Dr. Smith as Menidia beryllina, but they differ from typical 

 examples of the latter from the Potomac River at Washington, in the slen- 

 derer body, shorter dorsal, and in the dark dotting on the back. Head 

 4; depth 6i (7f to 8 in total). D. V-I, 9 ; A. 1, 17 ; scales 40. Eye very 

 large, longer than snout, 3 in head ; snout short and sharp, 2|, greatest 

 depth of body nearly 2 in distance from nape to first dorsal. First dorsal 

 just before vent, midway between tip of snout and base of caudal. Dark 

 dots on scales of back and sides ; lateral band sharply defined. Woods 

 Hole to Albemarle Sound, generally common in brackish waters, (gratilis, 

 slender.) 



Atherinichthys gracilis, GUNTHER, Cat., in, 405, 1861; no locality given. 



Menidia bergllina, H. M. SMITH, Bull. U. S. Fish Comm., x, 1890, 70, pi. xx, fig. 2. 



Represented in fresh waters of the Potomac River by the deeper-bodied 



1162a. MENIDIA GRACILIS BERYLLINA (Cope). 



Head 4 to 4 ; depth 5 to 5| ; eye very large, 3. Dorsal V-I, 10, rarely 

 V-I, 11 or V, I, 9 ; anal I, 15 to 18, usually I, 16 or 17 ; scales 38 to 40-8.
