A COMPARISON OF AUSTRALASIAN AND AMERICAN 
SPECIMENS OF HEMISQUILLA ENSIGERA (OWEN, 1832) 
(CRUSTACEA: STOMATOPODA) 
By WituiAM STEPHENSON! 
Drs. Raymond B. Manning, John C. Yaldwyn, and the present 
author each decided independently and simultaneously that the status 
of the Australian specimens of Hemisquilla merited reconsideration. 
Drs. Manning and Yaldwyn graciously consented to this author’s 
undertaking the main investigation while at the Allan Hancock 
Foundation. Here, California material was available mostly from 
the Hancock Foundation collections. Australian material has been 
obtained from various museums in Australia (particularly the Aus- 
tralian Museum, Sydney). Chilean material was limited to the 
small, complete collection of the Smithsonian Institution; unfor- 
tunately no recent collections from Chile have been obtained. Dr. 
John C. Yaldwyn has kindly loaned me the only known New Zealand 
specimen. 
Institutions referred to by abbreviations are: Allan Hancock Foun- 
dation (AHF); Australian Museum, Sydney (AM); Dominion Mu- 
seum, Wellington (DM); Scripps Institution of Oceanography (SIO) ; 
United States Nationa) Museum, Smithsonian Institution (USNM). 
_ Measurements throughout are in millimeters. Carapace lengths 
were measured with dial calipers, and other dimensions with the 
1 Department of Zoology, University of Queensland, St. Lucia, Brisbane, 
Australia.
