Peromyscus maniculatus gambelii (Baird) 



"H[esperomys] Gambelii/' Cooper, Zoology, in Cronise, 

 The Natural Wealth of California, 1868, p. 444 (A general 

 note is inserted to cover all the Peromyscus). 



"Hesperomys Gamhellii" Cooper, Amer. Nat., 3, 1869, p. 

 473 ("The common woodmouse of California.") 



"Hesperomys sonoriensis LeC." (part). Cooper, Proc. Cal. 

 Acad. Sci., 4, 1870, pp. 67, 68 (Range does not, so far as 

 known, extend north of "Southern Coast Slope"). 



Specimens examined. — Four : Nos. 5626, 5627, Univ. Calif. 

 Mus. Vert. Zool. ; Nos. 5652, 5653, Mus. Comp. Zool. Harvard 

 Univ. No. 5626: obverse of label "Hesperomys Gamhellii 

 Wilmington Cal. Oct '65, J. G. C". No. 56271 obverse of 

 label "Hesperomys calif ornicus. — Great-Eared mouse [printed 

 strips pasted on] 9 Sta Cruz Cal. Apr 8th, '66, J. G. C." 

 Cooper had written "Hesperomys Californicus" on the label, 

 the printed strips having been pasted over his written name. 

 No. 5652, obverse of label "Hesperomys sonoriensis- juv. Sati- 

 coy Cal. May 1873 J. G. C"; No. 5653, obverse of label (er- 

 roneously attached here) "Perognathus parvus Saticoy Cal 

 Mch. 73 J. G. C." 



Specimens (Nos. 5626-5627) prepared in the usual manner, 

 skulls inside skins, fore legs folded on breast, etc. ; abdominal 

 slit in No. 5626 not closely sewed up ; hind feet in this specimen 

 disposed at right angles to body in the region of the base of the 

 tail, tails not skinned. In No. 5627 the hind feet are broken 

 so that care must be exercised to avoid separating them from 

 the body completely. Nos. 5652-5653 have been made over 

 into modern museum skins ; the skulls have been removed ; that 

 of No. 5652 is uncleaned, and its posterior portion has been cut 

 away as was customary with Cooper in preparing his specimens. 

 I have not seen the skull of No. 5653. 



The October example of Peromyscus maniculatus gambeiii 

 from Wilmington, California, is buffy in coloration, with some 

 admixture of black; the April specimen from Santa Cruz is 

 intensely warm buff to ochraceous-buff, likewise with some 

 black intermixed. No. 5652 from Saticoy is a typical juvenal.
