Upon looking up Baird's original description of navigator 

 (1857, p. 11) it becomes apparent that one character ascribed 

 by him to the subspecies does not hold in our specimens, nor in 

 those of which measurements are given by C. H. Merriam 

 (1895b, p. 93). Baird asserts that the tail is considerably longer 

 than the body, evidently meaning head and trunk together, or 

 total length minus the length of the tail vertebrae. Elliot repeats 

 the statement (1901, p. 379). In all the specimens in the 

 ]\Iuseum, and in all those considered by C. H. Merriam (1895b, p. 

 93) except the type, which is a much shrunken alcoholic, the 

 length of the tail vertebrae is exceeded by that of the head and 

 trunk. 



Examination of the first upper molars shows the specimens 

 to belong to the subgenus Neosore.r (see C. H. jMerriam, 1891, 

 p. 35). They lack the distinct secondary tubercle which is said 

 to chara.cterize the subgenus AtopJiyra.r, but seem to possess a 

 very definite sulcus separating the antero-internal cusp of the 

 first upper molar from the posterior triangular cusp formed by 

 the cingulum. This is given as one of the characters of Ato- 

 pJiyra.r. Probably there is considerable variation in this regard. 



In his "Synopsis of the American Shrews of the Genus 

 Sorex" (1895b, p. 92) Merriam examined no specimens from 

 Nevada. But their discovery in the Pine Forest Mountains 

 might well have been anticipated, as record stations are present 

 to the eastward in Nevada and to the westward in California. 



Myotis lucifugus longicrus (True). 

 Long-legged Bat. 



A single specimen referable to this form was shot at the 

 Duffer Peak meadow on the evening of July 31, 1909 (8400 feet). 

 Five or six bats were flying about the lake, and occasionally one 

 would skim along the surface of the water. It seemed to be 

 characteristic of these bats to come out very late in the evening. 



]\liller (1897, p. 65) in his list of material of this form ex- 

 amined, recoi'ds a skin from the ( 'offouwood Range, Nevada. 

 This is east and south of the Pine Forest Mountains, but not 

 more tlian fifty miles distant. The present is the first record 

 known to the writer from the latter mountains.
