litt .). The mistaking of collectors' names for localities is too 
common an error in specimen lists. For instance, Raul de los Rios, 
a Peruvian who contributed to the collections of the American 
Museum of Natural History, has been more than once honored as a 
place name. 
"Brasil: Goias: Rio Panaua, Rio Acati-Parana (R. Mittermeier, 
pers. comm.)". The Parana do Panaua runs into the Auati-parana at 
02°00'S, 66°11'W in the state of Amazonas, not Goias. (Podocnemis 
unifilis l. 
"Brasil, Para: Igarape, Belem (MZUSP 2693)". This is not, as 
suggested, an igarape (creek) in or near the city of Belem, Para. 
It is an igarape called Belem, at 03°55'S, 69°37'W, in the state of 
Amazonas, near the Colombian border, about 21 degrees of longitude 
from Belem. ( Platemys platycephala ). 
"Brasil, Amazonas: Lagoa Silva, Saracu (MCZ 2601)". The 
correct locality is Lago Saraca, Silves (Dick, 1977). 
( Rhinoclemmys punctularia ). 
"Brasil, Goias: Maripasoula (ZSM unnumbered)". Maripasoula 
(03°38'N, 54°02'W) is in French Guiana, on the right bank of the 
river Marouini (=Marowijne). 
"Brasil, Pernambuco: Pacao (UMMZ 103242)". The locality is 
Pogao (08°11'S, 36°43'W). ( Kinosternon scorpioides ). 
The faulty map of G. carbonaria and these mistakes in the 
general list of localities make it necessary to examine the 
treatment of denticulata by Pritchard and Trebbau. In this regard 
there are also serious problems. Three localities cited on the 
list are omitted from the respective map (their figure 40): 
Anapolis in Goias, Descalvado in Mato Grosso and Nioague (old 
spelling Nioac) in Mato Groso do Sul. As it can be seen in my Map 
2, and will be commented below, the inclusion of these localities 
considerably changes the general picture. 
Pritchard and Trebbau ( loc . cit : 226) state that the 
"easternmost limit of the Amazonian distribution appears to be 
reached at the Serra do Tiracambu, Edo. Maranhao, and the Serra 
Dourada, Goias". 
In fact, the easternmost limit of the distribution of G. 
denticulata coincides with the easternmost limit at the hylaea 
itself, a little to the east of the Rio Gurupi, on the Para- 
Maranhao border, close to two MZUSP localities cited by Pritchard
