"would appear to replace the capistratus [= S. niger Linn.] in 

 the south-western parts of America." While no definite type 

 locality (a thing unknown in those days) is given, the range 

 of Bachman's texianus, as stated by him, practically coincides 

 with that of Baird's limitis. 



With these changes the Western Fox Squirrels will stand

FURTHER NOTE ON Notophorus. Since the foregoing was passed for 

 the press I have received pages 153-156 of Vol. XV of the ' Proceedings ' 

 of the Biological Society of Washington, dated June 20, 1902, which 

 contain, among other notes, a short paper by Mr. Oldfield Thomas, en- 

 titled ' The Generic Names of the Peccaries, Northern Fur Seal, and Sea 

 Leopard.' I am pleased to see that Mr. Thomas and I agree in con-

 Tayassu by a classical term, but he happened to mention only one 

 species belonging to it, viz. : ' Sus tajassu Lin. Gmel.' This therefore," 

 he continues, "would not only be its type, but would by elimination 

 restrict Tayassu and Dicotyles to the other species mentioned in the 

 respective original descriptions of those genera. Dr. Merriam's
