 erate depth; head depressed, slightly arched; snout short, blunt; chin 

 steep; mouth directed upward; lower jaws the longer, firmly united; 

 an outer series of broad, cusped, hooked teeth firmly set in each jaw, 

 behind these a band of smaller ones, sharp, pointed, expanded and 

 hooked near the apex; anal fin in advance of dorsal; intestine long; 

 scales large. (Garman.) 



124. Glaridichthys latidens (Garman). 



Glaridodon latidens Garman, Memoirs, Mus. Comp. Zool., xix, 1895, 

 42, pi. v,vfig. ii (teeth); Chihuahua. 



Head about 3^; depth about 3>^; D. 8; A. 10; scales 28 to 30. 

 Body moderately elongate, compressed; snout short, blunt, rounded; 

 chin very steep; mouth rather wide, arched transversely, directed 

 upward; teeth chisel-shaped, hooked and strong in the outer series; 

 inner teeth in bands, pointed, commonly expanded near the apex as if 

 2 or 3 cusped; eye large, longer than snout, 3 in head; dorsal origin a 

 little behind the middle of the total length, above middle of the base of 

 the anal; ventrals Very small, not reaching anal; pectorals moderate, 

 reaching behind bases of ventrals; caudal as long as head, subtruncate 

 or convex ; vertebrae 13-4-19=32. 



Color light olivaceous, darker on back, silvery on opercles; throat 

 and belly apparently somewhat lighter along the middle of the flank ; 

 narrow brown vertical bars on the sides, more distinct behind the ab- 

 domen, one of them situated below the extremity of the base of the 

 dorsal ; fins clouded with brownish ; top of head dark ; a dark line from 

 anal to caudal; in cases a smaller line on the middle of the side; the 

 brown color in punctulations, sometimes arranged toward the edges 

 of the scales. (Garman.) 



I do not know this species, and I am inclined to think there is some 

 mistake in the locality given for it. I do not believe this genus is 

 represented in northern Mexico.
