found in Western Australia, as is also the genus Aprasia, which ought 

 in my Catalogue of Slender-tongued Saurians (Ann. Nat. Hist. vols, 

 i. and ii.), to have been arranged with the Apodel Seines. On examin- 

 ing Mr. Gould's better-preserved specimen, I am inclined to consider it 

 also as the type of a family characterized by the shields of the head 

 and the position of the nostrils, to which most probably, MM. Dumerii 

 and Bibron's genus Braehymeles will also have to be referred. These 

 genera will then range thus :— 



Fam. Lialisid^e : — Lialis. 



Fam. Pygopidje :—Pygopns, Delma. 



Fam. RhodonidjE : — Rhodona Soridia Chelomeles. 



Fam. Aprasiad^e -.-—Aprasia Braehymeles. 



Ronia, Gray. Fam. Scincidse. 



Head rather shelving, shielded with one transverse frontal and two 

 large vertebral plates, the hinder largest ; the rostral plates large, 

 with two unequal supercilliary plates. The nasal plate triangular, 

 interposed between the rostral plate and the frontal ones, with the 

 nostrils in its centre ; loreal plates two, square ; labial plates large ; 

 ears none, only a very indistinct sunk dot in their place. Body 

 cylindrical ; tail conical, tapering. Scales smooth, ovate, imbricate, 

 of the belly 6-sided. The front limbs very small, rudimentary, 

 undivided ; the hinder limbs moderately developed, ending in two 

 very unequal toes, with distinct claws. 

 Ronia catinulata, Gray. Back with eight series of small black dots, 

 one dot on the centre of each scale ; cheeks, black, speckled; sides 

 and beneath whitish. 

 Body 3|| tail 2$ inches. 

 Inhab. Western Australia. Mr. J. Gould. 



The scales under the tail are rather larger, and the spots on the tail 

 are rather larger than those on the back. 



Grammatophora cristata. Nape with a crest of distinct, rather short, 

 curved, compressed, spinose scales ; back and tail with a series of 

 compressed scales forming a slight keel; occiput with separate 

 short strong conical spines ; sides of the neck and back with folds 

 crowned with series of short compressed scales ; base of the tail 

 with some scattered larger scales. In spirits, dull olive ; crown 

 black with large white spots, beneath black; middle of the belly 

 and under sides of the base of the tail white ; tail with black rings, 

 at the ends ; feet whitish. 



Inhab. Western Australia. Mr. J. Gould. 



The underside is coloured somewhat like G. maculatus (G. Gaimardii
