are all the canine animals noticed. The authour fully agrees with Prince 
Maximilian that the Fox is distinct from the Can. cinereo-argentatus of 
North America. Six species of Cats, besides the domestic, form a for- 
midable list of purely predaceous quadrupeds. They are 26. Felis Onca, 
L., (Yaguar) ; 27. Fel. concolor, L., (Guazuara); 28. Fel. Pardalis, 
L., (Chibiguazu); 29. Fel. macrowra, Wied, of which Dr. Rengger 
saw onlya mutilated specimen; 30. Fel. Yaguarondi, Desm., (Eyra- 
hu); 31. Fel. Eyra, Desm., (Eyra-pyta) ; and 32. Fel. Catus domes~ 
ticus. L. No, 30. appears to be considered by our authour as peculiar 
to Paraguay, and as having been hitherto described by D’Azara only : 
we presume therefore that he excludes from this species the larger indi- 
viduals from Surinam and Essequibo, which have been ascribed to it by 
M. Temminck and other writers. Both it and No. 31, which had cer- 
tainly remained unnoticed except by D’Azara, are very fully described. 
The Marsupialia comprehend only three species; a circumstance 
calculated to excite some surprise when we recollect that D’Azara 
deseribes twice that number. But it must be observed that the latter 
authour embraced in his work a much more extensive tract of country ; 
and this may also account for the absence from the present publication of 
several other animals described by him. The species in question, all 
designated by the native name of Micuré, are: 33. Didelphis Azare, 
Temm.; 34. Did. lanigera, Desm.; and 35. Did. crasstcaudata, Desm. 
There is much interesting information, which we regret that we have not 
space to analyze, relative to the mode of reproduction of these singular 
animals. 
Of Rodentia we have thirteen species, of which four belong to the 
genus Mus, These are: 36. Mus Anguya, Desm.; 37. Mus rufus, 
Desm. ; 38. Mus callosus, Rengg.; and 39. Mus longitarsus, Rengg. 
The two latter are described as new. No. 38 is said to be in appear- 
ance hke a young Mus Rattus; but the bristles surrounding the mouth 
are much shorter, being scarcely six lines in length; the ears are oval, 
nine lines in height and six in breadth; the tail does not run out into a 
point, but ends abruptly, and is curved downwards; the claw of the 
rudimental thumb is perfectly flat; and there exist on the soles of the
