theory of the vertebrate nature of the limbs of the higher animals. 

 [VERTEBRA.] 



Pclvi of Scheltopusik, showing at a a the rudiments of the posterior 

 extremities. 



Scheltopusik (Pieudopus Pallatii), 



Saurophit telradactylia is the Telradactylus Chalcididas of Merrem, 

 Lacerta tetradactyla of Lacepede, and Sawophis Seps of Fitzinger. 

 It is a native of the southern point of the African continent. 



The genus Chamasawa approaches the Zonwidce, but Dr. J. E. Gray 

 has constructed for this genus a distinct family, with the following 

 characters : 



Chatnsesauri (Chamcesawidce). Head covered with regular many- 

 sided shields; tongue nicked; palate toothless; temple scaled like 

 the back ; eyelids distinct, lower scaly. Body subcyliudrical, elon- 

 gate, the whole except the head covered with rings of elongate keeled 

 scales, forming longitudinal series ; limbs rudimentary. Ears distinct, 

 small ; no lateral groove ; sides rounded, covered with scales like the 

 back. It is a native of Africa. 



The only genus and species is the Chamcesaura, anguina, the Anguine 

 Lizard. It is the Lacerta anguina of Liunicus, and is an inhabitant 

 of the Cape of Good Hope. 



SavropMt tetradactylut. 



Anguine Lizard (CliamresaHra anguina}. 



It is interesting to trace in the Saurians the gradual deterioration 

 and aoolition of the extremities till the form becomes completely 

 serpentine. In Heterodactylns there are still five fingers ; but the 

 first finger of the anterior feet is so very short as to be rudimentary. 

 In Chalcis (Cophias, Fitzinger) there are five toes before, but only 

 three, reduced to tubercles, behind. In Scmrophis the toes on each of 

 the feet are reduced to four. In ChanKesaura, there is but one ou 

 each foot. In C/iirotet the anterior extremities are short indeed, but 

 5-toed ; the posterior extremities are altogether absent. In Bipes the 

 hind feet are each terminated by two unequal processes or toes. In 

 Pygopus the anterior extremities are also lost, and the posterior 

 extremities appear in the form of a foot in which no toe is to be 

 seen externally ; and in the Scheltopusiks all trace of external 

 extremities is lost, though the rudiments of posterior extremities 

 may be seen attached to the pelvis. [CHALCIDES ; CHIROIES ; BIPES.] 



ZONURUS. [ZONURIM.] 



ZOOCARPES, a group of Cryptogamic Plants, so named on account 

 of the locomotive character of their spores. [ALG.E ; DIATOMACE.E ; 

 DESMIDEJE.] 



ZOO'PHYTA (from ftfov, animal, and cfwToV, plant). This is the 

 title most generally employed for the Radiated and Phytoid forms of 

 animal life, included by Liunceus in his great divisions of Vcrmcs, 

 namely, V. Mollusca, V. Lithophyta, and V. Zoophyta. Under this 

 title Cuvier ranked the Intestinal Worms, which are more analogous 

 to Annulosa; and most writers include Sponges and Corallines, which 

 others rank with plants. [POLYPIFERA ; POLYZOA.] 



ZOOTOCA, a genus of terrestrial Sauna, nearly allied to Lacertn. 

 Both these genera are described in the article SAURIA. As they 

 have both of them British representatives we here present engraving-; 

 of them.
