Usually banded in rather gaudy colors on a yellow ground, two 

 rather faint orange bands being especially constant; and further 

 differing from its allies in never being flammulate or obliquely 

 striped. It varies interminably in color and band-pattern. 



Although known to naturalists of the last century, the locality of 

 this species still remains uncertain. Timor, the Tenimber islands, 

 and the Moluccas have all been given as its habitat, but lack con- 

 firmation by recent collectors. The locality Keffing Is. is upon the 

 authority of a German who, returning from the Dutch East Indies, 

 assured Prof, von Martens that it came from that place. The speci- 

 mens in collections were collected by Malays, and obtained at the 

 seaports, from Singa] ore down. It must be abundant where found. 

 The name Icevis would be as appropriate to most Amphidromtis, as 

 nearly all the species are smooth.
