8. FUNDULUS. 323 



the interorbital space is contained twice and three-tifths in the length 

 of the head. The diameter of the eye is two-thirds of the length of 

 the snout or of the width of the interorbital space, and one-fifth of 

 the length of the head. The origin of the dorsal fin is midway 

 between the extremity of the caudal and the anterior or posterior 

 margin of the orbit, and corresponds to the sixteenth scale of the 

 lateral line. The first anal ray corresponds to the second of the 

 dorsal fin. Anal much higher than long. Greenish, with three 

 more or less interrupted irregular longitudinal bands in the female, 

 and with many broad cross bands in the male.

Hydrargi/ra vernalis, Cuv. & Val. xviii. p. 206, pi. 531, appears 

 to be identical with If. majalis, differing from it in its coloration 

 only, having a dozen vertical black stripes on the sides of the body.

 The height of the body is one-fourth of the total length (without 

 caudal), the length of the head one-third ; eye one-fifth of the 

 length of the head. Head low and elongate, snout produced, the 

 lower jaw scarcely projecting beyond the upper. The origin of the 

 dorsal fin is midway between the extremity of the caudal and the 

 anterior or posterior margin of the orbit, somewhat m advance of 

 the anal. Anal fin much higher than long, especially in the male. 

 Body with nine narrow black' cross bars in the female ; dorsal fin of 

 the male with a small black spot on its hinder margin. 

 Indianola, Texas, Florida. 



This species is very closely allied to F. majalis, biit would appear 

 to differ in the number of the fin-rays and in the coloration. We 

 have examined an adult female in the Liverpool Free Public 

 Museum.

The height of the body is nearly one-fifth of the total length (with 

 the caudal), the length of the head two-ninths. Head quite flat 

 above, the width of the interorbital space being scarcely more than 

 that of the orbit, which is somewhat less than one-third of the length 

 of the head. Lower jaw slightly prominent. Caudal truncate. 

 Greenish olive, with a silvery longitudinal band, and with twelve or 

 fifteen blackish vertical streaks. ( Val.')
