31, Captain McClellan and a small party^^ were engaged in 

 explorations of Naches River and Naches Pass, while the 

 head of the main Yakima River and Lakes Keechelus, 

 Kachess, and Clealum were explored September 4 to 12 

 (Stevens, 1860, pp. 139-141). Evidently the type came 

 either from the headwaters of the Naches River or from one 

 of the lakes at the head of the main Yakima River. Since 

 these places are within twenty miles of each other, the type 

 locality of Neosorex p. navigator may be regarded as fixed 

 with a fair degree of precision.

Specimen examined. — One: No. 7187, U. S. Nat. Mus. 

 (in alcohol) ; an old label in the bottle, from which the writ- 

 ing has almost disappeared, reads "583 Vespertilio S D" 

 According to the Museum catalog, in which the specimen 

 was entered January 19, 1864, the bat was collected by "Mr. 

 J. Cooper," in California. 



The specimen is in fair condition, except that the hair has 

 sloughed off the skin of the posterior half of the body. The 

 skull has not been removed.

" It is probable that Dr. Cooper accompanied Captain McClellan on this side trip. 

 Baird (1857, p. 465) lists a specimen of "Hesperomys gambelii" collected by Dr. J. G. 

 Cooper on "Nachess Pass, Cascade mountains, W. T." on "July 1, 1854." The date 

 19 evidently erroneous, for during July, 1854, Cooper was in western Washington 

 (see p. 74) ; but the record appears to indicate that Cooper did collect on Naches 

 Pass.
