Tayra barbara peruana (Tschudi). TAYRA. 



One was seen at Tambo Carrizal east of Balsas May 19. It trotted 

 down a trail carrying a bird in its mouth, its head held high and its 

 whole appearance one of satisfaction and nonchalance. I was standing 

 near the trail without my gun and it did not see me until within a few 

 feet when it dashed off in another direction. Another was seen at 

 Moyobamba by Mr. Anderson under similar circumstances. 



Conepatus zorrino Thomas. SKUNK. 



An old male, Menocucho. 



The type locality of C. zorrino is Eten, a short distance north of 

 Menocucho and less removed from the actual coast, but the fauna of 

 the two places differ but little. The skunk obtained at Menocucho is 

 evidently somewhat larger than the type of zorrino and it differs also 

 in the white stripes which do not extend to the base of the tail but stop 

 at the flanks as described for the more southern species, C. arequipce. 



Flesh measurements are: Total length 670; head and body 418; tail 

 vertebrae 252; hind -foot 85. 



Conepatus sp. 



An adult female from Hacienda Limon is not definitely identifiable 

 without comparison with types. 



Rhynchiscus naso (Wied). 



Eight specimens, Nazareth, Yavari River. 



The favorite roosting place of these bats is the under side of a tree, 

 stub, or large rock overhanging the water. Such backgrounds blend 

 well with their coloration but are frequently so exposed that at short 

 distances one has no difficulty in distinguishing animal from vegetable. 

 When disturbed they flit away together like a company of butterflies' 

 and quickly attach themselves to the nearest similar roosting place, 

 often not flying more than twenty feet. They seem to cling to rather 

 than hang from the nearly perpendicular surfaces and although the head 

 and angles of the wings may be free the abdomen and tail membrane 

 are pressed flatly against the bark or stone. The number found together 

 was from ten to twenty and although specimens were secured only at 

 Nazareth, many were seen along the Paranapura River between Bal- 

 sapuerto and Yurimaguas.
