Scapanus californicus minusculus Bangs, Proc. New England Zool. Club, vol. 1, p. 70, 

 July 31, 1899. 



Scapanus latimanus minusculus Miller, U. S. Nat. Mus., Bui. 79, p. 10, December 31, 

 1912. 



Type locality. — Fyffe, El Dorado County, California. 



Type specimen, — No. 9189, Mus. Comp. Zool., Harvard College, 

 Bangs collection; $ young adult, skin and skull; collected July 15, 

 1897, by W. W. Price and E. M. Nutting. 



GeograpTiic range. — Known only from type locality. 



General characters. — Similar in size and color to S. I. occultus, pos- 

 sibly very slightly larger; skuU higher and narrower through brain- 

 case than that of occultus; inferior mandibular notch very shallow, 

 the angle of mandible being much shorter than in occultus. 



Color. — Type, in summer pelage: Upperparts hair-brown; under- 

 parts deep mouse gray. 



Skull. — ^Much like that of S. Z. occultus, but braincase narrower, 

 higher, and more rotund; inferior mandibular notch very shallow, 

 much shallower than in occultus; angle of mandible short and weak. 



Measurements. — Type (young adult female) : Total length, 160; tail 

 vertebrae, 31; hind foot, 21. Skull: Type (yoimg adult female): 

 Greatest length, 31.9; palatilar length, 12.6; mastoidal breadth, 

 15.3; interorbital breadth, 7.1; maxillary tooth row, 10; mandib- 

 ular molar-premolar row, 9.7. 



Remarks. — The type and only-known specimen of minusculus is a 

 female, barely adult, the status of which can not be determined until 

 more specimens are obtained from the type locaUty. The essential 

 differences from S. I. occultus are in the skull, which is relatively 

 narrower and higher and with the inferior mandibular notch very 

 shallow; the hind foot is longer than that of occultus. This form, 

 however, seems to be isolated from occultus by the interception of 

 sericatus. In color the type of minusculus is much like some speci- 

 mens of S. I. dilatus. 



Specimen examined. — One, the type.
