trating the first mentioned so-called genus was referred by Theo- 
bald to Plestiodon of Dumeril and Bibron, and renamed by him 
P. scutatus, and the other species for which Blyth had suggested the 
generic term Plocederma was placed by Theobald in the genus 
Laudakia, which he regarded as distinct from Ste//io, and referred to 
Gray’s species Sfellio tuberculatus. 
Before considering the affinities of these two forms I shall first 
point out the characters of the sub-genus Lwmeces which Wieg- 
mann, its author, regarded as only a subdivision of his Section Hu- 
prepes. 
In the Catalogue of the Berlin Museum published in 1856* 
Lichtenstein identified Plestiodon Aldrovandi, D. and B., with 
Seincus pavimentatus. P. Geoffroy St. Hilairet, but justly retained 
for P. Aldrovandi, D and B.{ Schneider’s name auratwn§ which, 
even according to Dumeril and Bibron’s showing, was entitled 
by priority to stand for the species to which they had affixed. 
the name of Aldrovandus. Prof. Peters|| was the first after 
Wiegmann himself to direct attention to the fact that the S. pavi- 
mentatus, Is. Geoff. St. Hilaire was the type of Wiegmann’s sub- 
genus Lwmeces and Dr. Stoliczka] last year brought Peters’ 
observation to the notice of this Society. 
The history of the sub-genus Zumeces is as follows: In 1834, 
Wiegmann** in establishing the genus referred S. rufescens, 
Merr., and 8. punctatus, Schneider, to it, but in the following year}t 
he pointed out that these two species did not belong toit. In 
1837,{{ he indicated that umeces was intermediate between 
Gongylus and Euprepes and that S. pavimentatus, Is. Geoff. St. 
Hilaire, was the only species referable to it, and that it differed 
from Luprepes in the form of its tongue and dentition, but he did 
not regard these differences as of generic but only of sub-generic
