344 NINTH ANNUAL REPORT OF 



39. FUNDULUS MULTIFASCIATUS, CuV. 



Fundulus multi/asciatus, Cuv. and Val., Hist. Nat. des Poiss. XVIII, 

 200. — Hijdrarp^ira multifasciata, Lesueur. — De Kay, New York 

 Fauna, Fishes, 220. 



This species was found everywhere associated with H. jiavula, but 

 in quite hmited numbers. 



40. Hydrargira flavula, Storer. 



Hydrargha jlavula, Storer. — Esox flavulus, Mitch. — Fundulus fa sciatus, 

 DeKay, New York Fauua, Fishes, 216, plate xxxi, fig. 98. 



This species may be called the giant of the northern cyprinodonts, 

 attaining a size only approached by the females of Fundulus zebra. As 

 in F. zebra, the female is considerably larger than the male. Specimens 

 were taken nearly eia;ht inches in len2;th. 



The H. flavula is very rarely found in the ba3's and meadows, the 

 few that occur in such localities being very small, and much scattered. 

 It is along the beach, and about the inlets, that the immense numbers 

 that exist on our coasts can be appreciated. As the tide is rising and 

 flowing over flat sands, or up the narrow shores and channel ways, 

 this species will be seen in dense schools, slowly swimming with 

 the tide, and readily recognised by its large size and the light spot near 

 the dorsal fin. 



It generally keeps distinct from the alherinas, which are equally or 

 even more abundant in the same situations. A few Cyprinodon ovinus 

 are sometimes seen in company, rarely any other species of the same 

 family. 



The sexes of this species are conspicuously different in marking, the 

 male having many broad vertical bands on each side, from head to tail, 

 the female two or three lonsitudinal ones. 



41. Hydrargyra luci^, Baird. 



Hydrargira Iucue, Baird. — General form elongated, though of rather 

 short appearance. Head constituting less than one-fourth of total length. 

 Insertion of anal slightly in advance of origin of dorsal, and rather 

 more developed than the latter. Vertrals very small; their extremity 

 reaching the anus. Tail large. D. 8 ; A. 9 ; C. 6, 1. 8, 7, 1. 5; V. 6; 

 P. 15. 



Dark olive green above, lower part of sides and beneath rich ochre 

 yellow. Sides with 10 or 12 broad, well defined, vertically disposed' 

 dark bars, nearly as large as their inter-spaces, which are of a faint 

 tint of greenish white. All the fins but the dorsal are of a uniform 

 yellowish, lighter than the abdomen. Dorsal, yellow on the terminal
