GENERAL NOTES. 



TYPE OF THE GENUS ATHERURUS, BRUSH-TAILED 

 PORCUPINES. 



The latest published statement of the type of the genus Atherurus F. 

 Cuvier, so far as I am aware, is that by Dr. T. S. Palmer in his excellent 

 Index Generum Mammalium (North American Fauna, No. 23, 1904, p. 127), 

 where it is erroneously given as Hystrix fasciculata Shaw (Gen. Zool. II, 

 pt. 1,1801, p. 11), from Malacca. By reference to Shaw's descriptions, which 

 are accompanied by good figures showing the peculiar tail bristles of the 

 genera Atherurus and Trichys, H. fasciculata is readily seen to be a member 

 of the genus Trichys. F. Cuvier (Diet. Sci. Nat., 59, 1829, p. 483), mentions 

 no type for the genus Atherurus, but says of the tail, " est longue et termi- 

 nee par un faisceau de lanieres cornees, aplaties et 6tranglees d'espace en 

 e^pace," which agrees with Shaw's figure and description of Hydrix ma- 

 croura Linnaeus based on Seba's Porcus aculeatus sylvestris etc. (Seba I, p- 

 84, pi. 52), and not with Shaw's Hystrix fasciculata, the tail of which is 

 " terminated by a tuft of long, flat hairs, or rather small, white laminae re 

 sembling strips of parchment." F. Cuvier refers Atherurus back to his 

 brother's Les Atherures (Regne Animal, 1829, p. 215), which refers in turn 

 to Buffon (Supplement, VII, p. 303, pi. 77). But Buffon's Malacca porcu 

 pine with its parallel-sided tail bristles is clearly Giinther's genus Trichys, 

 and not Cuvier's " Les Atherures." As the only name available for the 

 porcupine with the beaded tail bristles at the time of Cuvier's description 

 is Jfystrix macroura Linnaeus, this name should stand as the type of 

 Cuvier's genus A thrrurus. See Jentink (Notes Leyden Museum, 1894, p. 

 207), who pointed out the type of Atheruras to be Linnaeus' Hystrix ma 

 croura. Marcus W. Lyon, Jr. 



NOTE ON LIMNOMYS. 



In the Annals for March* I founded a new genus for a water-rat from 

 New Guinea allied to Hydromys and gave it the name Limnomys. But I 

 now find that this name was preoccupied for a genus of Muridae from the 

 Philippines discovered and described by Dr. E. A. Mearns.f I therefore 

 propose to rename the Papuan genus Drosomys, its type species becoming 

 Drosojnys asper. Oldfield Thomas.
