GENERAL NOTES. 



A NEW NAME FOR THE GENUS RHYNCHONYCTERIS PETERS. 



Rhynchonycteris, the name applied to a genu.s of Emballonurine bats, 

 by I'eters in 1867*, is preoccupied by Rhinchonyctrrig Tschudi 1844-4Gt, 

 a synonym of J Ho?(ra. The earUer name Proboacidca propo.^ed by Spix 

 in 1S2I!; and recently nsed by Allen§ is similarly invalidated by the Pro- 

 boscidea of J. G. Brugiere, 1791 1|. In the absence of any otlier pnl>lished 

 name, the genus, type Vespertilio natta AVied, may be known as R]i\jnch- 

 iscus. — Gerrit S. Miller, Jr. 



A SPECIMEN OF BISOX OCCIDEXTALIS FROINI 

 NORTHWEST CANADA. 



Examples of Bison occidentalis 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 occidentalis. It was found by Indians in the cut 

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

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

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

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

 ter, 105; transverse diameter, 10"); circumference at base, 312; lengthen 

 upper curve, 22o; length on lower curvi', 2S.t; extent from tij) to tip, 660. 

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

 ferred to tliis species, but otherwise no 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 {Chelopus inscidplus) 

 August 19, 1906, on the Maryland shore of the Potomac, near Phnnmers 

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

 as it appears to mark the extreme S(juthern 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.
