Leiolepisma cyanogaster (Lesson). 
A beautiful example from IVIer Island. It is appareutlj’ identical with 
specimens from New (Ininea and New Jlritain. 
Leiolepisma fuscum Dumeril et Bibron. 
This species is represented in the collection by specimens from Eadn or 
Mulgrave Island, Mer Island and Daridey Island. I have also received 
it recently from Mossman in (Queensland. These specimens difi'er con¬ 
stantly in coloration from the topotyjies which I collected in Waigiu and 
from the many others from the IMoluccas and Papua collected at the same 
time. Doubtless several distinct geographical races occur within this 
species, as in Dasia smaragdina. 
Leiolepisma peronii (Dumeril et Bibron). 
A single example from Kuranda in (Queensland. 
Leiolepisma aibertisii (Peters and Doria). 
A beautifully preserved suite of twenty-seven specimens from ]\fer 
Island and one from Prince of Wales Island. The specimens from Mer 
Island are astonishingly unvarying in their color pattern. This stability 
of coloration in authentic specimens from the sairie locality has been 
impressed upon me more and more since my study of the living seines at 
various localities in the Moluccas and Pai^ua. 
Homolepida crassicauda (A. Dumeril). 
A fine specimen from Darnley Island, Torres Straits, whence the species 
does not seem to have been recorded before. It is known from IMurray 
and Cornwallis Islands. 
Sphenomorphus quoyi (Dumeril et Bibron). 
A well preserved adult from Kuranda, Queensland. 
Cryptoblepharus boutonii peronii (Cocteau). 
The specimens before me from Darnley Island, Prince of Wales Island, 
and Mer Island seem to agree with this race and can not he ditierentiated 
inter se. Their coloration is distinctive and remarkably uniform. The 
various races of boutonii have sometimes very restricted and usually well 
defined ranges and within this species coloration is an extremely valuable 
diagnostic feature. It must he noted, however, that these little creatures 
are easily carried from place to place especially by aboriginal commerce 
or migration and that much of the old material in IMuseums is probably 
incorrectly labelled as to locality. Thus it becomes increasingly ditticult 
to limit the ranges of the forms as commerce and intercommunication in¬ 
crease. This race, peronii, apparently occurs in Waigiu, Papua and the 
Torres Straits Islands, hut I have had no specimens from the Australian 
mainland to compare with them. Roux records it also from Aru Islands.
