cular rugosities; nuchal shield large, considerably longer

New Guinea. 
The above, extracted from the Zodlogical Record for 
1901 (Rept. and Batr., p. 28), is the sum of the information 
of whch I am possessed regarding this species. 
It is much to be regretted that foreign authors, when 
writing on Australian subjects, do not see their way to sending 
copies of their papers to the various societies and museums of 
Australasia, and by this simple means averting the inevitable 
confusion which must occur by the redescription of their 
genera and speogies. Such an act of thoughtfulness would be 
greatly appreciated by their fellow workers here.
