MILLIPEDS OF MEXICO AND CENTRAL AMERICA 19 



TYPE LOCALITY: Mexico. 



In the copy of Silvestri's paper (loc. cit.), which he sent me, he had 

 canceled "Messico" in the title and in the species habitat as well, and 

 had written "Brasile" in both places. No other collections of the spe- 

 cies have been reported and it seems most likely that it is truly Brazil- 

 ian.
