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 posterior rays of the 

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

 by us. (versicolor, variegated.) 



Girardinus r<>r*i>lr. GATHER, Cat., vi, 352, 1866, San Domingo. (Coll. Mr. Cuming.) 

 1016. HETERANDRIA OCCIDENTALIS, Baird & Girarcl. 



Head 3| ; depth 4 to 4. 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 2| 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 Poecilia than 

 to the typical species of Heterandria. (occidentalis, western.)

316. LEBISTES, De Filippi. 



Lebistes, 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. 

 (Aei&'af, a small fish, from A/fy?, a kettle ; a pot fish.) 



1017. LEBISTES PCECILIODES, De Filippi. 



D. 9 ; A. 7; V. 6 ; scales 34-8. Barbadoes. Length H inches. (Giinther.) 

 (Pcecilia', eUoc;, likeness.) 

 Lebistes pceciliodes, DE FILIPPI, Arch. Zool. Anat., i, 1862, 69, Barbadoes; GUNTHER, Cat., vi, 356, 



*"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, we 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." Gunther.
