CYPRINODONT FISHES. 1003 



series of dark bars ; dorsal with anterior edge dark and usually 

 a blackish spot or band posteriorly near base. 



Cuba. 



Several specimens up to 70 mm. in total length. 



19. Pamphorichthys, gen. nov. 



Mouth small ; bones of lower jaw firmly united ; a series of 

 firmly set, slender, pointed teeth and a band of much smaller 

 teeth within. Intestine long, coiled. Males with anal and 

 pelvic fins below pectorals, the former a slender pointed organ 

 about ^ the length of the fish (without caudal), the latter also 

 modified, the outer rays produced, the inner about i as long and 

 forming a projection near their ends. 



This genus is based on Garman's Heterandria minor, which 

 seems to difi"er from Heterandria in the more slender teeth, 

 longer intestine, and shorter intromittent organ, but especially in 

 the modification of the pelvic fins in the male.

20. Pamphoria, gen. nov. 



Mouth small ; bones of lower jaw rather firml}^ joined ; a series 

 of broad incisors and a band of minute tricuspid teeth within. 

 Intestine long." Males with anal fin much advanced, forming an 

 intromittent oi"gan that is longer than the head, and with the 

 second ray of the pelvics produced.

Cat. Fish. vi. p. 350. 



Mouth small, transverse ; bones of lower jaw loosely connected ; 

 an outer series of slender curved teeth, somewhat exj)anded and 

 compressed towards their apices, spoon-shaped or oar-shaped. 

 Males with the pelvic fins enlarged, nearly as long as the intro- 

 mittent organ, which is unprotected by a hood, but has the 

 distal end remarkably modified (text-fig. 172 D). 



Two species from Mexico, with the intromittent organ precisely 

 similar in structure.
