5G4 Mr. G. A. Boulenger on new Lizards. 



Pygopus schraderi. 



Readily distinguished from P. lepidopus by the smaller 

 scales, the dorsals further differing in being but feebly keeled, 

 and in the shorter tail. 29 scales round the body, 97 pairs 

 of large ventrals. 14 femoral pores. Pale reddish brown 

 above, head with large dark brown blotches above, one on the 

 occiput being connected with a broad crescentic dark brown 

 band on the nape; a dark brown bar on the lips below the 

 nostril, a second below the eye, and a spot between the latter 

 and the nuchal band, which involves the ear. 



From snout to vent G5 mm. ; tail 60. 



A single young specimen, also from Milparinha, received 

 with the Gymnodactylus asper. 



Gerrhonotus gadovii. 



Head-shields smooth ; three large prefrontals forming a 

 triangle or the azygous shield (= frontonasal) in contact with 

 the frontal ; two pairs of shields between the azygous pree- 

 frontal and the rostral, with or without a small shield 

 between the anterior pair ; nasal well separated from the 

 rostral ; two superposed postnasals ; two or three loreals ; 

 two or three outer supraoculars and four to six supraciliaries; 

 ten or eleven upper labials. Side of neck with granular 

 scales. Lateral fold very strong. Dorsal scales in 16 or 18 

 longitudinal series (8 on the nape), the 8 median series 

 strongly keeled, the others feebly keeled ; 42 to 48 trans- 

 verse series from occiput to base of tail. Ventral scales 

 nearly as large as dorsals, in 12 longitudinal series. The 

 adpressed fore limb reaches the eye or not quite so far; hind 

 limb one-half to three-fifths the distance between axilla and 

 groin. Tail subquadrangular and often a little compressed 

 at the base, once and three-fifths to once and two-thirds as 

 long as head and body ; upper caudal scales nearly as 

 strongly keeled as the dorsals. Brown or brownish olive 

 above, with small darker spots or lichen-like darker and 

 lighter variegations ; sides with dark and light spots, often 

 with black, light-edged vertical bars, which may be pro- 

 duced obliquely, as chevrons, on the back ; a dark brown or 

 black streak on each side of the head, passing through the 

 eye, bordered below by a yellowish-white streak extending 

 to the angle of the mouth ; upper lip more or less spotted or 

 speckled with brown or black ; lower parts yellowish or 

 greenish white, more or less profusely dotted or spotted with 

 black.
