GARMAN: REPTILES AND BATRACHIANS FROM AUSTRALASIA. 3 
Gidura Mayerli, sp. nov. 
Plate 2, Fig. 2-2c. 
Form similar to that of @. marmorata ; depressed, elongate, transversely 
banded. Head depressed, large, long, subtriangular, pointed in front, widest 
between the ears and the eyes, concave on the forehead; snout as long as the 
distance from eye to ear, blunted at the end, one and one-half times the length 
of the orbit. Ear opening oblique, two-thirds as wide as the eye. Limbs 
medium, depressed, in large specimens as broad as the apical expansions, nar- 
rower in the young. Apical expansions broader than long, with a pair of 
rounded plates. Four pairs and a number of undivided infradigital plates. 
Head plates small, flat, smooth, nearly uniform in size, irregularly polygonal 
in shapes, larger between the eye and the nasal plates. Rostral large, eight 
sided, about twice as wide as high, with a slight median cleft above. Nostril 
surrounded by six plates, rostral, first labial and four nasals ; upper two nasals 
large, anterior largest and meeting the opposite nasal behind the rostral. 
Eleven labials; nine lower labials. Mental subtriangular, truncated and in 
contact with a heptagonal submental which separates the first pair of lower 
labials ; enlarged submentals in contact with all the lower labials, their sizes 
decreasing regularly to the small subgulars. Back, sides, and belly covered 
with small hexagonal to subcircular smooth scales larger than those of the 
head ; scales of the belly larger ; caudal scales broader than long, subhex- 
agonal. Femoral pores twenty. Tail long, five sixths as long as the body, 
slightly depressed, thickened anteriorly, tapering backward to a point, not as 
wide as the body. A single rounded and flattened tubercular scale at each side 
of the base of the tail. 
Adults are brown to light grayish brown, with a whitish band from the end 
of the snout below the eye across the ear and around the occiput on the nape, 
top of head lighter, four narrow transverse bands of light color across the back 
and six around the tail. The anterior of the bands on the body is above the 
shoulder, and the posterior is above the vent. The lower surfaces are whitish. 
On young specimens the brown is nearly black and the transverse bands are 
whiter and, the sides being brown, are more distinctly separated from the white 
of the lower surfaces. 
This differs from the @. marmorata in the separated infralabials, the larger 
submental scales, the greater number of femoral pores and the longer more 
slender tail. Named in honor of Dr. A. G. Mayer.
