indistinct dark band along middle of side, and above it 2 or 3 reticu- 

 lated black spots, their number and situation being variable, even on 

 the two sides of the same individual ; a black lino along the lower and 

 upper margins of the tail ; a blackish blotch on the jiosterior rays of the 

 dorsal fin. San Domingo. (Giinther.) Known from 2 females; not seen 

 by us. (versicolor, variegated.) 



Girardiniis rersicnloi; Guntiier, Cat., vi, 3r>2, 18GG, San Domingo. (Coll. Mr. Cuming.) 

 1016. HETERANDRIA OCCIDENTALIS, Baird & Girard. 



Head 3i ; depth 4 to H. D. 7 or 8 ; A. 9 or 10 ; scales 29-8. Body deep, 

 elevated in front of dorsal. Insertion of dorsal nearer base of caudal 

 than tip of snout, slightly in advance of anal. Brownish above, dotted 

 with black; silvery below, with a black lateral stripe, as broad as eye, 

 from shoulder to caudal; a narrow black line along lower margin of 

 tail; fins unicolor, without spot or blotch. Length 2i inches. Gila 

 Basin, Arizona, and basins of Yaqui and Sonora rivers, Sonora ; locally 

 abundant in springs and ditches ; our specimens sent from Tucson by 

 William W. Price and Herbert Brown. This species looks like a Gambusia, 

 but has a much smaller mouth. It seems nearer allied to PocciUa than 

 to the typical species of Heterandria. {occidentalism western.)

Lehistes, De Filippi, Arch. Zool. Anat., etc., i, 1862, 69. 



Cleft of the mouth small, with the lower jaw projecting beyond the 

 upper; both jaws with a narrow band of very small teeth, those in the 

 outer series being the largest. Scales of moderate size. Dorsal and anal 

 fins short; anal in advance of the dorsal, with the second and third rays 

 much thickened and elongate in both sexes. Second ventral longest, 

 ending in a hook in the females. Island of Barbadoes. We know this 

 genus only from Dr. Giinther's abridgment of De Filippi's account. With 

 Dr. Giinther,* we doubt the correctness of the sexual characters assigned. 

 (?.ej3iac, a small fish, from ?.eihj(;, a kettle ; a pot fish.)

*"If the characters assigned to this very doubtful genus are correct, it differs in a very 

 extraordinary manner from the other fish of this family, in which sexual differences are 

 observed. From an inspection of the figure, wo should have considered the specimen to be a 

 male; but Prof. De Filippi says distinctly that the peculiar anal fin is found in the female as 

 well as in the male." — GiinOier.
