Lacerta vivipara. M. Eatio gives a very lengthened description of the 
different varieties observed by him in the Upper Engadin, where it is rather 
local and not very abundant. He has several times had occasion to observe 
that this species takes to the water, and tries to escape capture by remaining 
at the bottom until the danger has passed. Females have the trunk com- 
paratively longer than males. Bibl. Univ. 1864, p. 346, 
Earn. ZoNURiDiE. Dr. Peters (Proc. Zool. Soc. 1864, p. 377) 
vindicates the correctness of the word Caaua as the vernacular 
name of Gerrhosaurus robustus, against the assertion made by 
Kirk in the same journal, p. 58, that some misapplication of 
that word had taken place.

Earn. SciNciD^. Dr. Peters disapproves of the artificial 
method practised in this family, of establishing genera and sub- 
genera on trivial characters which sometimes are subject to 
variation, so that specimens of the same species are referred to 
two different genera. Monatsber. Berl. Acad. 1864, p. 387. 
Scincus meccensis (Hempr. & Ehrenb,), Wiegm. Arch. Ntrgesch. iii. 1837, 
p. ]27, has been reexamined by Peters, who considers it as a well-distin- 
guished species. Monatsber. Berl. Acad. 1864, p. 44. 
Pedorychus {Scincus) hemprichii (Wiegm. Arch. Ntrgesch. iii. 1837, p. 128). 
Peters directs the attention of herpetologists to this species, which has not 
been mentioned by any of the later authors. Monatsber. Berl. Acad. 1864, 
p. 44.
