from Yurimaguas, has unusually large teeth and certain cranial pecu- 

 liarities, which, if borne out by a series of specimens, might be regarded 

 as of subspecific importance. In the absence of any such series, the 

 range of typical marsupialis, heretofore including only Guiana and 

 Venezuela, 1 may be regarded as greatly extended to include also the 

 whole of northern Brazil to the base of the Andes. 



Didelphis marsupialis etensis Allen. ETEN OPOSSUM. 



Three specimens:. Menocucho (2), Hda. Llagueda (i). 



Opossums are generally distributed through the suitable parts of the 

 coast region of Peru, being found in greatest abundance near cultivated 

 areas where they find their favorite fruits more easily obtainable than 

 in wilder parts. Local name Our on. 



Didelphis paraguayensis andina Allen. ANDEAN OPOSSUM. 



Eight specimens: Hacienda Limon, near Balsas (3 ad. 4 yg.), Rio 

 Utcubamba, 15 miles above Chachapoyas (i). 



Two of the adult specimens are more richly colored than descriptions 

 indicate as usual for D. p. andina, but in the absence of material for 

 comparison it is not possible to determine whether or not this has 

 particular significance. 



Wild fruits, particularly figs, chirimoyas, and grenadillas, were 

 especially abundant in the vicinity of Hacienda Limon furnishing a 

 plentiful and most acceptable supply of food for the opossums. Partly 

 eaten chirimoyas and empty shells of grenadillas were scattered about 

 the ground under the trees in many places. One evening, while we 

 were encamped under a large wild fig tree, partly eaten fruits began to 

 fall into our midst at short intervals, even striking us on the head. 

 The guilty opossum was caught that night near the foot of the tree. 

 The local name Ouron in use for opossums on the coast of Peru is replaced 

 in the interior by Kangaluc. 



Metachirus canus Osgood. 



One specimen, the type from Moyobamba, was the only one obtained. 

 This was brought to us by a small boy who said it had been captured in 

 one of the numerous small groves of plantains in the village. 



The close relationship of this species to M. grisescens is evident and 

 the two may be expected to intergrade.
