including lateral line in its course, a distinct dusky streak, and though 

 ill-defined above, and below along its edges, its width equals at 

 least two eye-diameters. At caudal base it is slightly reflected 

 out on base of that fin. Dorsal and caudal otherwise largely tinted 

 with brownish. Other fins pale or more or less tinted like belly. 

 Pectoral slightly brownish above and towards its tip. 



Length 12| inches (caudal tips slightly damaged). 



Type, No. 19,990, A. N. S. P. Goose Lake, Oregon. 1879- 

 E. D. Cope. 



Only known from the above example. It differs from Catostoiuhf 

 occidentalis in the dark lateral streak. The very small scales on thi 

 body from the throat to the ventral origin number about 80 in 

 series, while my examples of C. occidentalis show between 65 and 70 



(Named for Goose Lake, Oregon.) 

 Catostomus snyderi Gilbert. 



Head 4| to 4f ; depth 4f ; D. iv, 10, i; A. iii, 6, i; scales (pockets') 

 about 60? in 1. 1. to caudal base, and 4 more on latter; 12 scales 

 above 1. 1.; 8 scales below 1. 1. to anal origin; 31 to 33 predorsal scales; 

 snout 2^ to 2 J in head; eye 6 to 6| ; mouth width 4| to 4^- ; interorbital 

 2|. Gill-rakers 16+10, 8. Scales between front of isthmus and 

 ventral origin 43 or 44. Length 15 and 16f inches. Two examples 

 from Klamath Lake, Oregon, from E. D. Cope, in 1879. 



Cope's reference to Klamath Lake material as Catostomus labiatus^ 

 cannot refer to these specimens. He later states that his largest 

 example is twelve inches long, and gives the following points at 

 variance: "Scales, 10 — 74 — 11; radii D. i, 11; V. 10; head 4.5 times 

 in length; eye 5.5 in head." 



Prof. Snyder has kindly examined two typical examples in Stan- 

 ford University. They are from the upper Klamath Lake. He 

 writes as follows: "Scales in lateral line, to end of last vertebra, 

 74 — 72; scales on base of caudal, beyond the above 3 — 3; scales 

 between isthmus and origin of - ventral, about 40 in one example. 

 The last count is doubtful on account of irregularity in the rows 

 and the poor preservation of the specimens." 

 Catostomus catostomus (Forster). 



Four small examples without data.
