NO. 5 MAMMALS OF PANAMA GOLDMAN 91 



log along the bank of a stream in the forest at 4,500 feet altitude was 

 devoured by some prowling animal. Another was shot in the same 

 vicinity one day by one of my men, as it climbed a palm frond 30 feet 

 from the ground. This was a full-grown animal, but, unfortunately, 

 the head was carried away by the shot and the specimen rendered 

 worthless. 



Specimens examined : Cana, 3. 



TYLOMYS WATSONI Thomas 



Watson's Climbing Rat 



Tylomys watsoni Thomas, Ann. Mag. Nat. Hist., Ser. 7, Vol. 4, p. 278, 

 October, 1899. Type from Bugaba, Chiriqui, Panama (altitude 800 feet) . 



The basis of this species was two specimens " caught on banks of 

 river " at Bugaba by H. J. Watson. The skull is described as much 

 broader and heavier than that of T. panamensis. Bangs (1902, 

 p. 32) notes four examples, collected by W. W. Brown, Jr., of which 

 he says : " The specimens from Bugaba are not only topotypes, but 

 were caught on the banks of the same stream as the type." Allen 

 (1904, p. 68) lists a specimen taken by J. H. Batty at Boqueron. 



An immature example from Cerro Brujo, with a broad, heavy 

 skull, is quite different from the Cana series and more like T. watsoni 

 to which it is provisionally referred, although the nasals and pre- 

 maxillse are conterminous posteriorly (in specimens of typical 

 watsoni the premaxillse exceed the nasals in posterior extent). It 

 was taken in a trap placed among the spreading aerial roots of a palm 

 at 1,000 feet elevation on the Atlantic slope of the mountain. 



Specimens examined: Bugaba (type locality), 3 1 ; Boqueron, 1 ; 

 Boquete, 1 *; Cerro Brujo, 1. 



TYLOMYS FULVIVENTER Anthony 



Fulvous-bellied Climbing Rat 



Tylomys fuliriventer Anthony, Bull. Amer. Mus. Nat. Hist., Vol. 35, p. 366, 

 June 9, 1916. Type from Mount Tacarcuna, Panama (altitude 4,200 

 feet). 



The type and only known specimen of this species seems sufficiently 

 distinguished by the russet and ochraceous-buffy colors of the under- 

 pays. In the other species inhabiting the general region the under- 

 pays are white. Additional examples are much needed in order to 

 determine the status and relationships of the various forms of the 

 genus. Anthony (/. c.) states that this rat was taken in a banana-
