THREE NEW AUSTRALIAN LIZARDS — OGILBY. 7 



of the diameter of the eye, and the distance between the eye 

 and the ear-opening is equal to that between the eye and 

 a point midway between the nostril and the tip of the snout. 

 Interorbital space broad, broader in comparison than in G. pla- 

 turus or G. cornutus. Ear-opening a narrow vertical slit, about 

 one third of the diameter of the eye. Body short and rather 

 compressed, barely two and a third times the length of the head. 

 Limbs long ; digits rather short and thick, subcylindrical at the 

 base, and but little compressed on the distal phalanges. Head 

 covered with small granules intermixed with rounded tubercles, 

 which are largest near the end of the snout ; outer margin of the 

 upper eyelid with two strong ridges upon which small tubercles 

 predominate ; two slight longitudinal folds on the sides of the 

 neck and a vertical fold in front of the forelimb, all of which are 

 more thickly studded with tubercles than are the surrounding 

 parts ; rostral hexagonal twice as broad as high, without any 

 indication of median groove above ; nostril directed posteriorly, 

 bordered in front by a large nasal, wliich is larger than the first 

 upper labial, and separated from the latter by a series of small 

 granules ; labials small, thirteen or fourteen upper and eleven 

 lower ; mental trapezoidal, bordered posteriorly by five small 

 granules ; body above covered by minute granules, intermixed 

 with rounded and conical tubercles ; limbs similarly protected, 

 but with the granules larger and the tubercles smaller ; below 

 with flat subimbricate granules ; no latei'al fold. Tail short, 

 broad, and thick, depressed, malleiform, not contracted at the base, 

 from which the enlarged portion expands at right angles ; the 

 expanded portion is formed of six broad transverse ridges, and is 

 quadrilateral ; its length is three-fourths of its breadth, which is 

 one-sixth more than that of the body at its broadest part ; it ends 

 almost as abruptly as it commences, and terminates in an attenu- 

 ated point, which rises from the postero-inferior margin of the 

 swollen portion, and is barely four-sevenths of its length ; the 

 tail is covered above by minute granules anteriorly and much 

 larger flattened subimbricate granules posteriorly ; on the former 

 portion there are four regular transverse series of strong conical 

 tubercles, on the latter a single series on each side near the margin; 

 sides with an upper series of very strong conical tubercles, and a 

 lower series of weaker ones ; below with subimbricate granules ; 

 attenuated portion covered with small rounded granules. 



Colors. — Head and neck above brown with darker and lighter 

 marbling and most of the tubercles yellow; the sides pale yellowish- 

 brown with irregular blackish bands, which are vertical on the 

 former and horizontal on the latter ; back brown with narrow 

 yellowish transverse bands, mainly caused by the prevalence of 

 that color on the tubercles ; sides and limbs light brown streaked 

 and marbled with darker brown ; under surface dirty yellowish-
