ON A STOMATCPOD NEW TO AUSTRALIA, WITH A LIST 
OF THE WESTERN AUSTRALIAN SPECIES OF THE 
ORDER. 
By 
W. B. Alexander, M.A., Biologist to the W.A. Museum. 
(Read 21st April, 1914.) 
On 16th March, 1914, the W.A. Museum received from Mr. 
Aldrich, the Chief Inspector of Fisheries, a large Squilla obtained 
in King Sound. It proves to be a male example of Lysiosquilla 
maculata , Fabr., which has not hitherto been recorded from the 
Australian coast, though in view of its wide distribution it might 
have been expected to occur in our tropical water, as it ranges from 
Japan and Oceania to South Africa and has also been found in the 
West Indies. The nearest localities from which it has previously 
been recorded are New Guinea, Goram, Amboina, Flores, and 
Christmas Island. 
Unfortunately the present example is in poor condition, the 
last four abdominal somites and the telson being missing. When 
perfect the specimen must have measured a,t least 250 mm. 7 a size 
which is only rarely exceeded in this species. The most interesting 
feature of the present example is the form of the rostrum, which 
approaches that of var. sulcirostris , Kemp, founded on a single 
specimen from the Andaman Islands. The specimen has, however, 
nine teeth on the dactvlus, whereas sulcirostris has only eight and 
typical maculata usually has ten and very rarely nine. The sixth 
abdominal somite, which also presents points of difference between 
maculata and sulcirostris, is unfortunately missing, but the present 
specimen, like sulcirostris , has the dark transverse bands much 
narrower than in Kemp’s figures of L. maculata. The W.A. Museum 
collection previously contained specimens of three other species of 
Stomatopods from the Western Australian coasts: — 
Squilla miles , Hess, without definite locality, 
Gonodactylus chiragra, Fabr., without definite locality, and 
Gonodactylus glabrous , Brooks, from Sharks Bay (pre- 
sented by Mr. Aldrich in 1913). 
Of these the first is a very rare species, the type having been found 
at Sydney, and the only other example previously recorded being 
from the coast of Victoria. G. chiragra is a very abundant form 
throughout the In do-Pacific region and is known to inhabit the west 
coast of Australia as far south as Swan River. G. glabrous is also 
a widely distributed Indo-Pacific species, but the only examples
