Helodermidj:. 
F. Bocourt gives a sketch of the views of authors with respect to Helo- 
derma. He associates with it, under the family Trachydermiy Wiegm., 
several lizards to which it offers considerable zoological affinities ; they 
differ from it in having smooth ungrooved teeth. Such a difference 
might at first seem to militate against their union with Heloderniay but 
this dental character, of great importance in the higher Vertebrata, has 
only a secondary importance among the reptiles, as is exemplified by the 
serrated teeth of Macroscincus coctcei, D. & B. The Trachydermi are 
arranged as follows : — 
I. Trachydermi Glyphodonta. Teeth grooved. 
Heloderma horriduniy Wiegm., described and figured, p. 297, pis. xx. e 
& xx.G. 
II. Trachydermi A glyphodonta. True pleurodonts, with grooveless 
teeth. 
1. Xenosaurus grandiSy Gray, p. 303, pi. 20 p, figs. 1 a-g. 
2. Lepidophyma flavo-maculatumy Dum., p. 306,, ipl. xx. P, figs. 2 a-g \ 
smithiy Boc., p. 209, pi. xx. p, figs. 3a & &, pi. xx. g, figs. 2 a & b. 
3. Cricosaiira typicay Gundl., Pet., p. 313, pi. xx. e. figs. 14-19. 
The above fully described and figured. Xantusiay Baird, does not 
seem to differ from Lepidophyma except in the ’form of the pupil.
