''^' Tullgrens statement that buclucaldi possesses the 

 same type of dentition on the fingers of the claw as does 

 narajitensis, i. e. teeth closs-set and contiguous. ulthough 

 nowhere does he specifically state that that such is the 

 case. 



In this connection it may be well to corree an error 

 in the literature that as come to my attention. It was first 

 noted by With in 1906, who however failed to correct 

 the mistake.
