ELGARIA GRANDIS. 213 



Descr. — There is quite a striking resemblance between this species 

 and E. scincicauda, and, upon a first glance, it might appear prema- 

 ture to regard them as distinct from one another. The most striking 

 difference consists in the proportional length of the tail, which, in the 

 present species, is nearly twice the length of the body and head to- 

 gether, thus, much longer than in E. scincicauda. The limbs are more 

 developed also than in the preceding species. There are fifty trans- 

 verse rows of scales from the occiput to the origin of the tail, ten of 

 which belonging to the region of the neck. The longitudinal series 

 are fourteen in number, and provided with a moderate keel. The 

 scales themselves are somewhat smaller than in E. scincicauda. The 

 mental shields are less developed than in the latter species. The same 

 is true with regard to the preanal scutellae or shields. The abdominal 

 shields are smaller in the same proportions as the dorsal scales. The 

 scales covering the anterior and upper parts of the limbs are almost 

 entirely smooth, whilst in E. scincicauda several of the upper series 

 are distinctly keeled. One hundred and eight verticils of scales may 

 be counted from the base of the tail to its apex, which is very slender. 

 The upper scales are slightly carinated or keeled j the lateral and in- 

 ferior ones being smooth. 



The ground color is brownish-olive. The head unicolor. Eleven 

 dorsal, transverse, blackish bands, somewhat broken up along the back 

 and lower portion of the flanks, covering but one scale, leaving its 

 margin or else its tip whitish. These bands are more closely approxi- 

 mated in the present species than in E. scincicauda, in which we 

 observe generally three rows of intervening scales, whilst there are 

 only two in E. grandis. The inferior surface is unicolor. 



Loo. — This species inhabits Oregon.
