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,! may be regarded as greatly extended to include also the 
whole of northern Brazil to the base of the Andes. 
Didelphis marsupialis etensis Allen. EtTeN Opossum. 
Three specimens: Menocucho (2), Hda. Llagueda (r). 
Opossums are generally distributed through the suitable parts of the © 
coast region of Peru, being found in greatest abundance hear cultivated 
- areas where they find their favorite fruits more easily obtainable than 
in wilder parts. Local name Ouron. 
Didelphis paraguayensis andina Allen. ANDEAN Opossum. 
Eight specimens: Hacienda Limon, near Balsas (3 ad. 4 yg.), Rio 
Utcubamba, 15 miles above Chachapoyas (1). 
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.
