Dr. Rengger’s Mammalia of Paraguay. 469 
Rengg. Of these No. 6 is stated to bear a close resemblance to D’ Azara’s 
Chauve-souris troisiéme, admitted into scientific catalogues under the 
name of Phyllostoma rotundum. It differs, however, according to the 
authour, from the description of the latter given by D’ Azara, in the form 
of the nasal membrane; although on a comparison of the two descrip- 
tions we do not clearly perceive in what the difference actually consists. 
Unfortunately neither D’Azara nor Dr. Rengger furnish us with specific 
characters ; and we can consequently do little more with the new species 
established by the writer now before us than refer to his descriptions, in the 
attempt to abstract which we might lose sight of the most essential cha- 
racters. His Glossophaga villosa appears to have remained hitherto 
unnoticed; but his Molossus ce@cus is identical with the Chauve-souris 
neuvieme of D’ Azara, and his Woctilio ruber is the Chauve-souris onzieme 
of the same authour, removed from Vespertilio, in which it had hither- 
to been mistakenly placed, to Woctilio of which it has all the characters. 
The Plantigrade Carnivora observed by Dr. Rengger in Paraguay 
are the following: 17. Nasua socialis, Wied, (Cuati of the natives) ; 
18, Was. solitaria, Wied, (Cuati mondé) ; 19. Procyon cancrivorus, 
Geoff., (Aguarapope); 20. Gulo Barbarus, Desm.; and 21. Gulo 
vittatus, Desm., (both called Yaguape). With the exception of the 
Otter of the country, all the Digitigrada belong to the genera Canis 
and Felis, The Otter is distinguished from the Lutra Brasiliensis, Ray, 
under the name of 22. L. Paranensis, Rengg. The differences are 
stated to consist in the want, (in the latter species), of the white or 
yellowish longitudinal stripes on the under part of the neck, and of the 
reddish yellow spot on the breast, which are characteristic of the former, 
It has besides only four, instead of five, cheek teeth on each side of the upper 
jaw; and seems never to attain the large size of full grown specimens of 
the Brasilian species, no individual seen by the authour having mea- 
sured more than four feet in total length. It is added, on the authority 
of D’Azara, that the tip of the tail in full grown females is white, The 
Wolf, 23. Canis jubatus, Desm., (Aguaraguazu and Yagua pyta) ; 
the Fox, 24. Can, Azare, s. Brasiliensis, Wied, (Aguarachay) ; and 
25. the different varieties of the Can, domesticus, s. familiaris, L.
