interpretation is a grave error. "Sebastianopolis" used to be the 
erudite name of the city of Sao Sebastiao do Rio de Janeiro, Rio de 
Janeiro, in the state of the same name, and the latter is the 
proper type locality of type locality of Emys radiolata Mikan, 
1820. 
Another confusion, though with 
no taxonomic or nomenclatural 
occurs with regard to 
locality: "Sao Paulo:

Rio Ipanema (modern spelling) and 
Mogi Guagu (corrected spelling) are 
good Natterer localities, but they 
are 135 km apart. I consulted Dr. 
Franz Tiedemann, Naturhistorisches 
Museum Wien, who gave as his opinion 
that "Rio Ypanema", "aus den Seen 
bei Mogi Guaiu" and "Provinz Sao 
Paulo" are three independent 
localities. In fact, examination of 
Siebenrock's table ( loc . cit.) shows 
that indeed he used commas to 
separate individual place names; 
e.g., "Rio Negro bei Marabitanos, 
Barra do Rio Negro, Rio Solimoes", are undoubtedly three 
localities, not an explicitation of a single locality ( Hydraspis 
rufipes 1 . His use of the indication Provinz in the case of A. 
spixii, however, makes it probable that only two localities are 
involved, both in the then Province, now State, of Sao Paulo: the 
Rio Ipanema (enters the Sorocaba from the south at 23°34 / S, 47°36'W) 
and some pond near the city of Mogi Guagu (coordinates of the city 
correctly given by Rhodin et al.).
