From these measurements it would naturally be inferred that 

 A. bendirii varies considerably in its dimensions like all other species 

 of mammals, for even a California example is much larger than the 

 type of A. b. palmeri, separated on account of its size, which character 

 can hardly be considered to be sufficient to distinguish the two forms, 

 and in the absence of any other will necessitate the reduction of 

 A. b. palmeri to a synonym of A. bendirii. 



FAM. 

 SUBFAM. MYOGALIN^E. 

 NEUROTRICHUS. 



Neiirotrichus gibbsi major. 



Neiirotrichus gibbsi major. Merr., N. Am. Faun., No. 16, 1899, 

 p. 88. Elliot, Syn. N. Am. Mamm., 1901, p. 387. 



Seven specimens: 6, Eureka, California; i, Goldbeach, Oregon. 



I refer these specimens to this species as they all possess a dis- 

 tinct anterior cusp on the cingulum of the large premolar, this being 

 absent in examples of N. gibbsi. The extreme dimensions of the 

 specimens are, total length, 113-125; tail vertebrae, 38-42; hind foot, 



i5-5- l6 -5- 



Of this species Mr. Heller writes that its "habits are said to be 

 similar to those of Sorex, that is, no runways are made as is the case 

 with Scapanus, but they appear to live like shrews under logs, etc. 

 Food not known, but perhaps different from Sorex, as they will not 

 take bait, such as bacon, in the traps." 



SCAPANUS. 

 Scapanus townsendi. 



Scapanus townsendi. (Bachman), Jour. Acad. Nat. Scien., Phil., 

 1839, viii, pi. i, p. 58. Elliot, Syn. N. Am. Mamm., 1901, p. 391. 



Four specimens: 3, Crescent City, California; i, Goldbeach, 

 Oregon. 



These four examples are very large, much larger than the type, 

 and measure in the extremes as follows: Total length, 208-231; tail 

 vertebras, 42-46; hind foot, 26-28. 



At Eureka Mr. Heller states this species was "fairly common 

 throughout the redwood forests, and in moist bottom land. Several 

 skins preserved by the farmers were examined, all of this species: one 

 skin had large white anal and pectoral patches." At Crescent City this 

 mole was "abundant in black bottom soil; rarely found in red soil."
