No. 365. duvaucelU, Cnv. Lydekker accepts two subspecies of 

 No. 366. eldi, McCl. eldi for our region, viz., eldi, and 



frontalis, from S. Burma and Manipur 

 respectively. Thomas has more recently studied this group (J. B. 

 N. H. S.xxv, p. 364, 1918). He shows that the original of eldi 

 came from Manipur and not from Pegu, and that consequently 

 that name must be used for the form now called frontalis. The 

 true Thamin of Pegu being thus without a name, he proposes for it 

 that of thamin, at the same time raising it to specific rank alongside 

 of eldi ; finally he establishes a subspecies of thamin, viz., bruct i, 

 for the animal from the Ruby Mines, Burma. The four forms of 

 RuCERVUS (including duvaucelU) may be arranged in a key as 

 follows : — 



Key to the species of Rucervus. 



A. — Brow tine differentiated from the 



beam, leaving it at an appreciable 



distance above the burr 

 B. — Brow tine continuous with the beam, 



i.e., leaving it immediately above the 



burr. 



a. Under surface of hind pasterns 



horny 



b. Under surface of hind pasterns 



hairy. 



a^ Antlers spreading widely outwards 

 almost from the burr ... 



&!. Antlers rising parallel for an ap- 

 preciable distance, and then only 

 spreading feebly outwards
