behind, these fewer and somewhat smaller in a speci- 

 men 17 in. long. Base of anal three times in its distance 

 from snout, its longeSI rays equal to those of the ventral. 

 Caudal deeply forked. Lateral line present, but rather 

 taint. 



This species is closely related to the species described 

 by Bean as Ameiurus dugesii (Proc. U. S. Nat. Mus., 

 [879s 304 ), differing in having very prominent serrations 

 on the pectoral spines, the types of dugesii having the 

 pectoral spines without seme. I have examined a speci- 

 men of dugesii, 4 in. long, from Salamanca, Mew, which 

 is in the type basin. It has the cirri minute and light in 

 color, a row of papilhe along the lateral line, and the 

 pectoral spines with four or live degenerate seme. The 

 process from the occipital is as described above, and Mr. 

 Bean informs me that the types have the sides with hair- 

 like cirri. It. therefore, belongs in the same genus with 

 price/ and may stand as Villarius dugesii. 



This description is based on seven specimens (No. 4826, 

 L. S. Jr. Univ.), 7 to \^V> in. long, from San Bernardino 

 Creek, near the northern border of Sonora, Mexico. 



The species is named for the collector, Mr. William 

 Wightman I'rice.
