536 Bulletin American Museum of Natural History. [Vol. XXXIV, 
1771. Pennant. 
The Brasilian Musk Penn. syn. quadr. p. 58 n. 47. 
A compilation, based on the following seven authors: Margrave, Piso, Marchais, 
Bancroft, Seba, Klein, Brisson. The gist of his description 1s: “ About the size of a 
roebuck; both sexes without horns; hair short and smooth; head and neck brown; 
throat and lower part of neck white; body and legs tawny. Inhabits Guiana and 
Brazil.” This agrees, so far as it goes, better with the brown brocket than with the 
red brocket, especially in “the lower part of the neck”’ being white. 
Pennant evidently derived some of his account from Marcgrave’s description of 
the Cuguacu-ete (Brazil, etc., p. 235). Erxleben cites ‘Marcgrave’s Cuguacu-ete 
only among the references given by him under Cervus capreolus as ‘“Hune pertinere 
videntur.”’ 3 
Erxleben’s own diagnosis is as follows: ‘‘M. rufo-fuscus, ore nigro, gula alba.”’ 
His description, so far as it has significance, is: ‘‘ Pili breves mollesque, capitis collique 
supra fusci, colli subtus albi, corporis crurumque rufo-fusei... . Habitat in Guiania et 
Brasilia.” : 
To summarize the foregoing: Erxleben’s; Moschus americanus was 
obviously based primarily on Seba, his second citation; four of his other 
citations rest exclusively on Seba; two of the others are worthless; the 
reference to Pennant brings in a new element, Marcgrave,' not cited by 
Erxleben under Moschus, but doubtfully under Cervus capreolus. Other- 
wise Pennant adds nothing to the case.

1 Aside from the references to size and form, which are not diagnostic, the essential part 
of Marcgrave’s description of his ‘‘Cuguacu-ete Brasiliensibus’’ is: ‘‘Pilis vestiter glabris, 
qui in toto corpore, cruribus & pedibus rufescunt, in collo & capite fusci, sub guttere & infe- 
riori collo albo.” G. Cuvier (/. c., p. 56) summarizes Marcgraves description and adds. 
‘*Voila sans contredit, la femelle de notre petite espéce rouge-bai.”’ 
Kerr’s Cervus caguete is based on Marcgrave’s Cuguacu-ete, and this name may be con- 
sidered available (as Mazama caguete) for the red brocket of the Pernambuco district of east- 
ern Brazil, should it prove distinguishable from the red brockets of Surinam and southern 
Brazil
