The pelvis, No. 2744 e, of an enormous Asiatic Elephant in the Museum of the 

 Royal College of Surgeons of England is portion of a skeleton of, perhaps, one of the 

 largest individuals hitherto brought to Europe. The humerus is referred to at pages 59, 

 153 and 215, and shown in Plate XVI, fig. 4, and the femur at page 164. The perfec- 

 tion of the ossa innominata, which are completely anchylosed at the pubic symphysis, offer 

 some excellent measurements in comparison with the pelvic elements of the extinct 

 species, more especially the huge bones of E. meridionalis, from the Forest Bed in the 

 Norwich Museum. These are as follows : 



1. From the anterior superior spine of ilium to the symphysis pubis is 24^ (linear), and 

 27 inches by tape along the margin. In No. 225, E. meridionalis, Gunn Collection, 

 Norwich Museum, the former is 34 inches. 



2. From anterior superior spine of ilium along the upper border to the sacro-iliac 

 symphysis is 28 inches (linear), 33 by tape. In No. 225, Gunn Collection, the former is 

 48, and the latter G7 inches. 



3. Height from brim of acetabulum to the anterior superior spine of ilium 13 (linear), 

 15 by tape. In No. 225 these two are 18 and 21 inches respectively. 



4. Girth of neck of ilium 19J inches. In No. 225 it is 29| inches. 



5. Pubic symphysis to sacrum IS linear, round the basin 23 inches. In 225 the 

 former is 20 inches, latter 26 inches. 



6. Maximum breadth of ilium 16 inches. In 225 it is 25 inches. 



7. Sacro-iliac symphysis 14x9 inches.
