Fishes of the Order Cyprinodontes 15 



2, Profunduhts oaxacac Meek 



Fundulus oaxacae Meek, Publ. Field Mus. (Zool.), 3, 1902, p. 90 (original descrip- 

 tion) ; ibid., 5, 1904, p. 104, fig. 28 (redescription and figure of type material). 



Fxmdidus punctatus Regan, Biol. Centr. Am., Pisces, 1907, p. 78 (in part). 



As also in P. labialis and P. punctatus, the anal fin is higher in the female 

 than in the male ; it is also high in the young, as in punctatus. 



Re-examination of Dr. Meek's types from Oaxaca seems to confirm the 

 validity of his species. It is a smaller fish than punctatus, and the eye is 

 smaller than in specimens of the Guatemalan species of comparable size 

 (see measurements of each). The scales average fewer in the longitudinal 

 series, but more in the transverse series. The dorsal and anal fins are nearly 

 unicolor, whereas in punctatus these fins have a light marginal band, just 

 within which the dark pigment is intensified. The two species, however, are 

 very closely related, and may prove identical (as Regan has held after exam- 

 ining more abundant material).

3. Profundulus candalarius, new species 



Holotype, a male specimen 73 mm. long to base of caudal ; collected with 

 a female paratype of 68 mm. in a limestone spring at Candalaria, near the 

 Mexican boundary of Guatemala, 6 leagues distant from Nenton, on June 

 I, 1906. This is in the basin of the Rio Chiapas of the Atlantic drainage. 

 The specimens were collected by Mr. O. F. Cook, and both are deposited! in 

 the Field Museum of Natural History. 



P. candalarius in general appearance is similar to P. labialis Giinther, the 

 only species hitherto known in the Atlantic drainage, it having been taken 

 from Lake Yzabal and from tbe basin of the Rio Chisoy, tributary thereto.
