divided into several groups, as the True Seines 
(Semens'), having four legs, with small margined 
toes, and a sharp edged muzzle, which enable 
them to bury themselves with facility in the 
sand of the deserts they inhabit. 
Others have blunt noses, thin smooth scales, 
and long conical tails; as the New Holland 
Tiliqua (Lacerta Scincoides)\ the Ribbon Galley- 
Wasp (Lac, tceniolata) from New Holland,—but 
one of the New Holland kind (Trachydosaurus 
rugosus ), has large rugose bony scales, and a 
short depressed tail. 
Some of the Seines (Lygosoma) have very 
long slender bodies, and very small, weak feet; as 
the short footed Lygosoma (Scincus brachy - 
pus), and the dotted Lygosoma (L. punctatum). 
One of these Lizards, with nearly the same 
form of body, has only three toes to each foot, 
(Seps) ; as the common Seps (Seps Chalcides ) 
from the South of Europe : one of them differs 
by the ears being hid under the skin, as the 
Lacertine Siaphos (Siaphos cequalis). 
The Bipes are peculiar for having only two 
oblong lobes in place of legs. One of the 
species, the Brazilian Bipes (Pygopus Cariococca) 
from Brazil, has the tympanum hid under the 
skin, whilst in the New Holland species (. Delma ), 
Fraser’s Bipes (Bipes Fraseri ), the ears are as 
distinct as in the Seines. 
The Blind-worms (Anguis) have scales like the 
Seines,
