add, on a somewhat immature specimen of that species from near 

 the same type h)cality. It is very probable that Leconte's positive 

 statement, in his introductory paragraph to the description of 

 cognatus, that he had never, during a long period of residence in 

 Georgia, seen leucopus there, will be confirmed by future investi- 

 gators. 



Another species whose status is affected by the foregoing remarks 

 is Peromyscus megacephalus of northern Alabama. Not having se- 

 cured a series from that region I am unable to throw any light on 

 the question of the affinity of this species to gossypinus, to which it 

 is most closely related, and indeed it may be found to be only a case 

 of aberrant and extraordinary individual variation from typical 

 gossypinus, or may represent a mountain or foot-hill race of that 

 species. In either case the validity of megacephalus nowise affects 

 the status of mississippiensis, which represents the modifications of 

 an environment quite the reverse of that obtaining in northeastern 

 Alabama.

15. Peromyscus aureolas (Aud. & Bach.). Golden Mouse. 



Prof Baird, in his great work on the North American Mam- 

 malia (p. 468), tabulates two specimens of this mouse which were 

 taken near Kuoxville, Tennessee, by Prof J. B. Mitchell and pre- 

 sented to the Smithsonian Institution. Dr. Coues, in the Mono- 

 graph of North American Rodentia, specially refers to one of these 

 specimens as typical of the peculiar coloration of aureolus, so we 

 may reasonably accept the identification and the record as the first 

 for the State. Dr. C. H. Merriam writes me that his assistant, Mr, 

 H. C. Oberholser obtained one of these mice at Roan Mountain 

 Station. In view of these Tennessee records, which would indicate 

 the presence of the Golden Mouse over the greater part of the State, 

 it seems strange that I did not meet with it, although the Deer 

 Mouse was taken in considerable numbers. The elevation of Roan 

 Mountain Station is about 2,500 feet. Messrs. H. H. and C. S. 

 Brimley inform me that they have received numbers of this mouse 

 taken by J. S. Cairns near Weaverville, N. Carolina, about 25 miles 

 east of the Tennessee line, at 2,300 ft. elevation, so it is reasonable 

 to expect them in any of the passes of the Great Smoky Mountains 

 below that altitude.
