A single specimen from the Kadamaian River, Kina Balu, 

 2100 feet, preserved in the RafBes Museum. 



This species connects GecJco with Ptychozoon and stands 

 in the same relation to the latter genus as Hemidactylus 

 platj/urus does to Mimelozoon. The lesser development of the 

 parachute-like lateral membrane and the absence of differen- 

 tiation in the lepidosis of that membrane justify its allocation 

 to the genus Oecko rather than to Ptychozoon. 



StoliczTcaui borneensis. 



Rostral moderately large, triangular, not visible from 

 above ; a pair of very narrow internasals ; a pair of large 

 prsefrontals, separated from the frontal and supraoculars by 

 a series of small scales ; frontal a little broader than long, a 

 little shorter than the parietals ; supraocular very small ; 

 eye very prominent, with vertically subelliptic pupil, sur- 

 rounded by the supraocular, two or three praoculars, tlie 

 fifth labial, and 7 or 8 small scales ; nostril very large ; loreal 

 much longer than deep ; ten upper labials, the two last 

 longest; temporals small, scale-like; a single pair of small 

 chin-shields, in contact with three lower labials. Scales in 

 SO rows, those on the vertebral region and those adjacent to 

 the ventral shields largest, elongate rhomboidal, juxtaposed, 

 the others very small and separated by naked skin. Ventrals 

 210; anal entire; subcaudals 124. Rufous, with large 

 blackish spots, at least as large as the space between them, 

 disposed more or less regularly in three longitudinal series ; 

 brown beneath, the shields edged with yellowish. 



Total length 750 millim. ; tail 240. 



A single female specimen from Mount Kina Balu, 

 4200 feet. Raffles Museum. 



Oreocalamus, gen. nov. 



Agrees in every respect with MacrocaJamus, Gthr., except 

 in the presence of a pair of internasal shields.
