Fig. 2. 3. 4. is the distal end of a right humerus and is 

 a much smaller specimen than the above. Its general form 

 corresponds more nearly with Kutorga's Brithopus pri- 

 scus *) though smaller. It possesses the same ento- and 



irs^

ectocondyloid canals (both bridged over) which occupy 

 the same relative positions, but the deep pit which exists 

 thenally between the two canals in Brithopus is wan- 

 ting. The olecranal pit exists merely as a shallow, sub- 

 triangular depression of the surface of the flat expanded 

 distal end. The shaft was much constricted relatively to 

 the distal expansion. 



It seems to me undesirable to lay any fresh burden 

 on scientific nomenclature by affixing names to these 

 fragments. W'hen more connected portions of skeletons 

 are found, a better basis for generic names will exist. 

 At present I content myself with bringing the existence 

 of the above remains to. the Knowledge of the Society.
