Cantor observed this species in houses in the valley of Penang ; 

 and Stoliczka says it is the most common IIouse-Gecko all over 

 the island of Penang, along the sea-coast as well as on the top 

 of the hill, elevation 2500'. I found this Gecko swarming in 

 houses wherever I stayed in Penang and Singapore (also in Deli, 

 Sumatra), and, as Stoliczka says, from the sea-level to the top of 

 the hill : it is to be found both inside and outside buildings, and 

 I have also found it in gardens. It is very voracious, and will 

 attempt to seize any insect ; I have more than once seen a Oehyra 

 attack a full-sized Jlierodula vitrea and rep\ilsed. It shows great 

 ingenuity both in escaping capture and in obtaining its food. 

 It frequents lamps especially at night, to catch the insects attracted 

 by the light. Whenever these Geckos are about you hear their 

 cheerful noise, and also at intervals during the day when they are 

 out of sight in holes or under the roof. Cantor (p. 20), in describing 

 Gecho monarchus, says its cry resembles the monosyllable ' tok,' 

 repeated 6 or 8 times with increased celerity ; I have not heard 

 the cry of O. monarchus, but the above description well suits that 

 of Oehyra mutilata. 



These Geckos throw off their tails on the slightest provocation. 

 There was one living in the Officers' Mess at Penang, in which the 

 reproduced tail had grown bifid laterally. 



The young are very different in appearance to the adults, on 

 account of the slenderer body and tail and the coloration. 

 Stoliczka (J. A. S. B. 1870, p. 163) says "the young Hzard is 

 brown, with numerous rather large round pale spots all over the 

 body ;" but I have found them pale olive-brown with distinct dark 

 brown spots above, and immaculate bulf beneath. They seem to 

 vary greatly. The spots disappear as they grow larger. The adults
