third from the tympanic bone to the maxillary formed by the pro- 

 cessus mastoideus, which reaches to that point of the maxillary where 

 this bone is united with the pterygoid. As in Cijstiynatlms, there 

 is a large os intercalare between the frontal and parietal bones, with 

 distinct sutures in one of the skeletons, which in another are con- 

 founded with those bones. The sides of the skuU are more or less 

 ossified, according to the age of the individual. The coccygeal style 

 is not quite as long as the vertebral column, and pro\ided with a 

 high, sharp ridge. The clavicular are curved, with the convexity 

 behind ; in front of their symphysis is the manubriimi sterni, half- 

 cartilaginous, not bifid ; the coraeoid bones are rather feeble, dilated 

 at the' sternal end, and joined behind with a very large and broad 

 ossifying cartUage. Humerus with a moderate ridge, still lower in 

 the femur. The iliac bones have a slight longitudinal groove, are 

 just as long as the cms, and a little longer than the humerus.

* Fitzinger appears to have believed in the existence of a pouch on the belly ; 

 his denomination is derived from yaarfip belly, and 9r}Kri, used by the old anato- 

 mists for the brain-pan ; therefoi'e I think myself justified in not accepting his 

 name.
