CORRECTIONS REGARDING THE NAIVIES OF TWO RECENTLY 

 DESCRIBED AMPHIBIA SALIENTIA. 



Ill a paper on the Reptilia and Amphibia of Gorgona I.sland, Coloniljia 

 (Bull. Mas. Comp. Zool., vol. 46, no. 5, p. 101, June, 1905), the writer 

 described a new frog, to wliich by a curious inadvertence the name Pros- 

 theraspis ( i^ic) femoralis was given. This name is preoccupied by Pros- 

 therapisfemoralia Boulenger, described from the Huallaga River, northern 

 Peru (Boulenger, Proc. Zool. Soc, London, 1883, p. 635, pi. 57, fig. 1). 

 Since the Gorgona Island species is quite distinct, it must therefore be 

 re-named, and may stand as Prostherapis boulenger! Barbour. 



A correction is also to be made in the case of Cacopoidcs borealis Bar- 

 bour, described as the type of a new genus and species in a paper on 

 "Some New Reptiles and Amphibians" (Bull. Mus. Comp. Zool., vol. 

 50, no. 12, p. 321, April, 1908). It appears that this must now be con- 

 sidered identical with Callula verrucosa Boulenger, though consideral>ly 

 variant from the type of that species and vastly removed from it in range. 

 Boxilenger's specimen came from Yunnan, while that on which the sup- 

 posed new species was based, was collected at Antung, Manchuria.

THE AUTHORITY FOR THE NAME NYCTICEBUS MENA 



GEN SIS. 



The Philippine Slow Lemur was originally called menagensis without 

 assignment to any genus in an article in the Zoologischer Anzeiger for 

 1892, volume XV, page 147. Prof. H. F. Nachtrieb was apparently the 

 author of the article, but in a letter to me dated June 7, 1906, he attributed 

 the account as printed to Prof. Dean C. Worcester. (See Lyon, Proc. 

 U. S. Nat. Mus., XXXI, p. 531, footnote, November 9, 1906.) As a 

 specific name pnl)]ished without inclusion, even questionably, in any 

 genus has no valid standing, Ni/ciicebus mcr\agensis can not date from 

 1892 and can not be attributed to either Nachtrieb or Worcester. Mr. 

 Oldfleld Thomas has recently attempted to show (Ann. Mag. Nat. Hist., 

 8th ser. , I, p. 4<)9, June, 1908) that the name should date from Trouessart's 

 Catalogus INIammalium, 1897, and that Trouessart should be credited with 

 the authorship of the name as being the first to use menagensis in combi- 

 nation with a genus of lemurs. An earlier use of the name in a binomial 

 sense, however, was made by Lydekker in the Zoological Record for 1892, 

 volume XXIX, published in 1893, on page 25, under INIammalia, where the 

 com])ination Lemur menagensis occurs as well as a reference to the original 

 account of the species by Nachtrieli and Worcester. It would seem, there- 

 fore, that the scientific name of tlie Philippine Slow Lemur should stand 

 as Ngcticebus menagensis (Lydekker) and date from 1893.
