GENERAL NOTES. 



A NEW NAME FOR THE GENUS RHYNCHONYCTERIS PETERS. 

 Rhynchonycteris, the name applied to a genus of Emballonurine bats, 

 by Peters in 1867*, is preoccupied by Rhinchonycteris Tschudi 1844-46t, 

 a synonym of Anoura. The earlier name Proboscidea proposed by Spix 

 in 182/1 i and recently used by Allen is similarly invalidated by the Pro- 

 linxridea of J. G. Brugiere, 1791 1|. In the absence of any other published 

 name, the genus, type Vespertilio na*o Wied, may be known as Rhynch- 

 iscus. Gerrit S. Miller, Jr. 



A SPECIMEN OF BISOX OCCIDENTALS FROM 



NORTHWEST CANADA. 



Examples of Bison occidental-is are as yet so rare in collections that an 

 additional one is perhaps worthy of record. Among some specimens of 

 recent large mammals received by the Biological Survey from Charles 

 Sheldon, of New York, is an incomplete skull of a fossil bison, which 

 seems referable to Bison occidental! s. It was found by Indians in the cut 

 banks of a small creek which enters the Felly River some twelve miles 

 above Selkirk, Yukon Territory. The nasals, rostral region, palate, and 

 teeth are missing, but the cranium, orbit, and horn cores are well pre 

 served. Measurements of the horn cores are as follows: Vertical diame 

 ter, 105; transverse diameter, 105; circumference at base, 312 ; lengthen 

 upper curve, 2_?:>; length on lower curve, 285; extent from tip to tip, 660. 

 The length of the horn cores is rather less than in previous specimens re 

 ferred to this species, but otherwise 110 serious discrepancies appear. For 

 confirming my identification, I am indebted to F. A. Lucas, the original 

 describer of the species. Wilfred H. Osgood. 



AN EXTENSION OF THE RANGE OF THE WOOD TORTOISE. 



The capture of an individual of the wood tortoise (Chdopus insculplus) 

 August H), U)0(>, on the Maryland shore of the Potomac, near Plummers 

 Island, about 10 miles west of Washington, D. C., possesses some interest 

 as it appears to mark the extreme southern limit of the species, Havre de 

 Grace, as indicated by one specimen in the collection of the National Mu 

 seum, being the previous southernmost record. The specimen in question 

 has been added to the National Museum collection.
