Remarks. — As noted by Miller (1897, p. 80), the type specimen of 

 Myotis evotis chrysonotus has the tail injured so that its shortness in 

 comparison with that of typical Myotis evotis can not be regarded as 

 a valid character. Indeed the similarity of the type to Californian 

 examples was pointed out by the original describer, who remarked 

 that the animal would probably prove to be only a subspecies of 

 Myotis evotis, a suggestion which is well borne out by the larger 

 series now^ available. The lighter color as compared with the typical 

 form seems to be the only diagnostic feature of the race. At present, 

 however, it m'ust be recognized that the status of the subspecies of 

 Myotis evotis is far from satisfactory. Specimens from localities so 

 far apart as Montana, Lower California, and Vera Cruz are not 

 likely to represent one race; but the series of skins now available 

 has not enabled us to come to any final conclusions, though it seems 

 not improbable that the existence of a central and southern coast form 

 (TTiicronyx), an interior form (true ckrysonotus) , and a southern 

 Mexican form will eventually be demonstrated. 



In parts of western Colorado this bat appears to be less uncommon 

 than usual. Cary (1911) observes that he has not found it about 

 cliffs or ledges, the favorite resort of Pijnstrellus hespeims, but lisu- 

 ally in the vicinity of ranch buildings. Bats of this kind frequently 

 fly into houses in pursuit of insects attracted by a light. Cary found 

 a small colony, apparently of adult females and nearly full-grown 

 young, inhabiting a deserted ranch house at Sunny Peak, Routt 

 County, Colo., in August, 1906. Other than this there appear to be 

 no recorded accolmts of breeding colonies.
