In the skeleton of Hremias pulchella Gray which I have recently ex- 
amined the only epiphyses which can be detected are on the upper end of 
the humerus and at the distal end of the metacarpals and metatarsals. 
The skeleton of Varanus shows such close resemblances in the arrange- 
ment and position of the epiphyses to the skeletons of Amblyrhynchus 
and Heloderma that one is forced to the conclusion that they are closely 
related members of a natural group of the lizards. This relationship

has been claimed on other grounds and the arrangement of the epiphyses 
tends to corroborate this view. As in the two forms mentioned, there are 
in Varanus epiphyses present in abundance on the skeletel elements. 
Each end of the long bones of the limbs, each end of the metacarpals and 
metatarsals, the bases of all of the phalanges, including the ungual 
phalanges as in Heloderma, and some of the tarsal and carpal bones, are 
provided with epiphyses.
