[Tuber superior mihi, Processus superior Ecker] on the declining angle 

 of the iieum and serving to the adhesion of the muscles. 



I liave never yet found this protuberance developed to such a 

 degree although having examined the pelvis of the following species : 

 Rana jim-a Rös., a(:iills Thom., Lalastei Blgr., macrocnemis Blgr., 

 temporalis Gthr., jwpoiiica Gthr., chinensis Osb., tigriiia Daud., lim- 

 nocharis Wiegm., ocoipüalis Gthr., esrulenta L. and ridibimda Pall. 



The ilea of species nientioned are geneially characterised by the 

 following features : neck of ileum generally nai'iower or at the most 

 as broad as the depth of the ileuin measured somewhat before the 

 tuber superior; the ascending angle of the ileum proceeds in a straight 

 line along the upper margin of the crest of the ileum. Tuber superior 

 always moderately developed, outer side of ileum sinooth or with very 

 weakly developed bony-ridges for the adhesion of muscles.

The ileum of the new species on the contraiy has a much- broa- 

 der neck, the ascending angle always going over into the ileum's upper 

 margin in a broken line, but becomes gradually narrower directly 

 behind the tuber superior or as in the most characteristic cases, the 

 tuber superior protrudes in the shape of a bird's beak. 



On the outer side of the ileum we find three bony-ridges ser- 

 ving to the adhesion of muscles. A semilunar proeminence below the 

 neck of the ileum and directly before the glenoid cavity serves a 

 similar purpose. A deep canaliculation takes its origin below the tuber 

 superior which is strongly bent outward. 



Shoulder-girdle. Among the bones of the pectoral-arch I 

 found many coracoids, scapula's and 4 sternum. No essential differen- 

 ces are to be noted between these and corresponding parts in the 

 Common- frog.
