conical: mouth very oblique ; mandible deep and short, projecting ; pre- 

 maxillary protractile but not produced ; maxillary not reaching eye : 

 teeth very minute or almost obsolete, somewhat movable ; eye 4 in head ; 

 first rays of anterior dorsal over posterior end of ventrals and slightly in 

 advance of the insertion of the anal ; first rays of second dorsal over 

 middle of anal, the rays "when depressed reaching as far toward caudal 

 as the rays of anal; length of base of second dorsal about half that of 

 base of anal or equaling distance from snout to posterior edge of orbit : 

 longest rays of second dorsal slightly exceed in length longest rays of anal 

 or about equal the greatest depth, and about \ greater than the length 

 of the base. . Pectoral fins large, not falcate, 1^^ in head, inserted above 

 axis of body and reaching to middle of the ventrals, or about equal length 

 of longest dorsal rays ; origin of ventrals midway between snout and 

 last rays of anal, extending beyond vent almost to anal ; length equal 

 distance from snout to posterior edge of orbit. Eye large and full, longer 

 than snout, about 3 in head ; cheeks and opercles scaled, the former with 

 3 rows of scales ; scales all entire, rather firm. Color light olive-green, 

 with narrow but distinct and complete lateral stripe ; the 3 rows of scales 

 on back thickly sprinkled with minute dark-brown dots which extend 

 from the snout to the caudal fin. Length 2\ inches. Canals in the 

 City of Mexico and other tributaries of Rio de Lerma. In the City of 

 Mexico this species, together with Girardiniclithys, is sold in the market, 

 embedded in meal and baked in corn husks. (Woolman.) (Named for 

 David Starr Jordan.) 



Chirofitoma brasiliensis, Jordan, Proc. U. S. Nat. Mus., 1879, 299; not of Cuvier & Valenciennes. 



Ohirosloma jordani, Woolman, Bull. U. S. Fish Comm., xiv, 1894, 62, pi. 2, canals at Sala- 

 manca and in City of Mexico. The specimens of " Atherinichthys hrasilieusis " mentioned 

 by Giintlier as having been collected by Salle in Mexico probably belong to this species. 

 The types of Cliirostoma brasiliense (Quoy and Gaimard) came from Eio Janeiro, and this 

 species is certainly distinct from it. 



355- KIRTLANDIA, Jordan & Evermann. 



Kirllandia, .Tordan & Evermann, new genus, {vagrans). 



This genus is close to Menidia, but differs from it in having the scales 

 laciuiate and the dorsal and anal fins scaly. Three species known. 

 (Named for Dr. Jared Potter Kirtland, one of the first to study the fishes 

 of Lake Erie and the Ohio Basin. )

 base of caudal and posterior angle of opercle ; distance from its front to 

 front of second dorsal f head. Pectorals slightly shorter than head. 

 Vertical fins with large scales. Scales firm, adherent, then edges crenate
