Plate XII. A. 



Elephas N~amadicus (Falc. and Caut.) From the valley of the 

 Nerbudda. Probably a female, from small size of tusks. This 

 specimen was presented to the Museum of the United Service In- 

 stitution by Major Orlando Felix, and was received by him with other 

 Nerbudda specimens, from Lieut.-Colonel Ouseley. It was chiselled 

 out by Dr. Falconer, and determined by him to be a new species. In 

 a letter to Lieut.-Colonel Ousely, Dr. F. writes thus: 'It is probably 

 the most perfect specimen of a fossil elephant's cranium in Europe. 

 The species is especially interesting from the form of the cranium, 

 which is so grotesquely constructed that it^ looks the caricature of 

 an elephant's head in a periwig. I have named the species E. Nama- 

 dicus, after the Nerbudda river, the Namadus of Ptolemy.' There is a 

 very similar specimen in the Museum of the Asiatic Society of Bengal.
