Between the date of the original publication on the Diprothomo, 

 by Amegliino, and the completion of the writer's study of the speci- 

 men embocUed in tliis report, a number of pubUcations on the subject, 

 some of considerable importance, have appeared. Regrettably, not- 

 withstanding the weight of the problems involved and the unsatis- 

 factory condition of the data, in some cjuarters the new "precursor" 

 is being accepted with scarcely any critical reflection, as demon- 

 strated, but, as will be seen, there are also other opinions. 



A good abstract of Ameghino's memoir on the Diprothomo is given 

 by Rivet in L' Antliropologie} There is no discussion of the subject, 

 the re^'iewer ending his note with the expression that he ''hmits him- 

 self, without regret, to the role of a strict analyst."
