BEPTILES FROM QUEENSLAND 4- NORTHERN TERRITORY.— LONGMAN. 33 



concave. Rostral large, convex, wider than high, slightly emarginated above 

 where in contact with the internasal. Nostril pierced between seven nasals, the 

 anterior of which is the largest, the posterior being indistinguishable from the 

 scales of the snout. As in D. conspicillatus, L. and F., only one upper distinct 

 labial is present, the border being completed by about 26 small scales. The lower 

 labial border is formed by the anterior units (about 30) of several oblique rows 

 of granules which meet the gape ; mental with a small median process posteriorly. 

 Infer iorly, a few of the scales adjoining the mental are somewhat enlarged. Body 

 moderate; upper surfaces covered with small granules, the median dorsal series 

 not enlarged; abdominal scales smaller. Limbs slender, just meeting when 

 adpressed. The digits are covered interiorly with rounded tubercles, with two 

 small oval plates at the apex (which is scarcely dilated) ; all clawed. 



Tail (not reproduced) short, subglobose, being very convex above and 

 slightly concave inf eriorly ; the middle and posterior surface above is covered 

 with rounded or pentagonal convex scales, in the centre of each being a distinct 

 tubercle ; scales below flat and imbricate. No pores. At each side of the thickened 

 base of the tail is a cluster of small conical scales. 



Colour (spirits) greyish above, but far darker than D. conspicillatus, 

 especially on the head ; many of the scales are almost black, and these form an 

 irregular reticulated pattern. The region of the canthus rostralis is lighter. 

 Under surfaces whitish. 



Dimensions : Total length 60 mm. ; width of head 7-5 mm. ; snout to ear- 

 opening 10 mm. ; snout to anal opening 44-5 mm. ; fore-limb 13-5 mm. ; hind-limb 

 16 mm. ; tail 15-5 mm. ; max. width of tail 9-5 mm. 



Loc. : Port Darwin ; donated by Mr. G. F. Hill. 



Type in Queensland Museum : Reg. No. Q.M. J 14/1994. 



Through the courtesy of Mr. C. Frost, we have had an opportunity of 

 examining " a subtype" of I). conspicillatus, Lucas and Frost, 3 from Charlotte 

 Waters, Central Australia. Although in colour and dorsal and caudal lepidosis 

 these geckoes are very distinct, they have so much in common that D. hillii may 

 be looked upon as the Northern coastal equivalent of the eremian species. 



CEDURA MARMORATA, Gray. 



In a handsome specimen of this Northern gecko, forwarded from Port 

 Darwin by Mr. G. F. Hill, the first infralabials are not in contact behind the 

 mental, but are separated by an a2ygous scale or chin-shield.
