 Scolopendropsis thayeri Brolemann, Cat. Myr. Bresil, 1909, p. 32. 



Localities. — State of Bahia : Bahia, Iguarassu (the type locality of 

 inermis (Pocock)). State of Para: Santarem (the type locality of 

 thayeri (Mein.)). 



Kraepelin suggests the identity of thayeri Meinert with calcaratus 

 Pocock; but an examination of the type of thayeri shows that it is the 

 same as the inermis of Pocock and that both are the same as Brandt's 

 hahiensis Avhich has long priority. _ Through probable error twenty- 

 three pairs of legs were attributed to Brandt's species, although the 

 not very probable suggestion has been made that the species is di- 

 morphic, having some individuals with twenty-three and others with 

 twenty-one pairs of legs.
