The range of the Quica Opossum extends from Mexico, whence there are specimens 
in the Berlin Museum, to Brazil, where Dr. Burmeister obtained an example near New 
Freiburg. Schomburgk found it in Guiana, and Mr. Thomas includes it among the 
Mammals collected by Mr. Buckley in Ecuador. Dr. v. Frantzius considered it to be 
a rare animal in Costa Rica, or at least one which was seldom procured‘. 
In Guatemala, Mr. Sarg informs Messrs. Godman and Salvin, the Quica Opossum 
is common in Coban, living in the houses amongst old boxes, piles of wood, &c., where 
it makes itself a comfortable nest of scraps of paper. It wanders about at night, 
invading the kitchen, and feeds on what it can find, especially on oranges and other 
fruits, eggs, fowls, &c., but avoids meat. When pursued it defends itself with energy, 
showing and using its sharp formidable teeth.

Both the British and Berlin Museums possess specimens, collected in Costa Rica by 
Carmiol, of a small Opossum which appears to be certainly identical with the Brazilian 
species named Didelphys cinerea by Temminck. In the same country Dr. v. Frantzius 
obtained a single living example of an Opossum which he referred to D. myosurus, 
Temminck (=D. nudicaudata, Et. Geoffroy) ?.. The animal unfortunately escaped from 
its cage and was devoured by dogs, so that positive determination was rendered 
impossible, but it seems not improbable that it really belonged to the present species. 
In Brazil Prince Maximilian zu Neuwied says that the Ashy Opossum is very destructive 
to poultry, sucking their blood and devouring their eggs. Its odour is stated to be 
extremely offensive.
