AUSTRALIAN CUMACEA. No. 9 
THE FAMILY NANNASTACIDAE 
By HERBERT M. HALE, Director, Sour Ausrratian Museum, 
Fig. 1-49. 
INTRODUCTION. 
The material now dealt with was taken in shallow water off eastern and south- 
ern Australia, between latitudes 27° and 41° 8. Some of it was secured by offi. 
cers of the South Australian Museum, the bulk of it, as previously acknowledged, 
by Mr. K. Sheard, Division of Fisheries of the Council for Scientifie and Indus- 
trial Research, while thanks are due also to Mr. I. 8. R. Munro (Assistant Re- 
search Officer of the Fisheries Division), who very kindly recently submitted 
a formalized Cumacean collection made by him in Moreton Bay (Brisbane), 
Queensland. 
Searcely anything is yet known of the Cumacea of the northern coast of 
Australia and little more of those from the western coast. Russell and Orr (1931, 
fig. 1) published a map showing that most of the oceanographic research in the 
Western Pacific, prior to the Great Barrier Reef Expedition, has been concen- 
trated in the region of the Dutch East Indies and the Philippine Islands. Since 
then investigations have been carried out by the Department of Zoology, Univer- 
sity of Sydney, and the C.S. and I.R. Division of Fisheries. 
Famity NANNASTACIDAE. 
Picrocuma Hale, a genus with some unusual characters, is now referred to 
this family. Including the twenty-five species herein described as new, the thirty- 
four named members of the family occurring along the Australian coast are dis- 
tributed among the genera as follows: Nannastacus, 10; Schizotrema, 1; Cu- 
mella, 7; Prcrocuma, 1; Campylaspis, 14; Procampylaspis, 1, 
As regards Procampylaspzis, it is interesting to find south of the southern tro- 
pic a form which differs very little indeed from the boreal genotype (see remarks 
by Zimmer, 1913, p. 483 et seq.). 
Genus Nannastacus Bate. 
Nannastacus Bate, 1865, p. 86; Stebbing, 1918, p. 168 (syn. and key) ; Zimmer, 
1921, pp. 1388-134 (keys). 
Zimmer keys the species which have the peduncle of the uropod less than 
twice as long as the telsonie somite. He omits hirsutws Hansen which he considers 
is a Cumella, and is of opinion that sarst Kossmann is probably referable to 
Schizotrema. Only one species (gurney Calman) has been described as new 
since 1921. In 1936 [ recorded material of the genus from South Australia as 
representing three of Calman’s species. Since then further specimens have been 
collected and it is now considered that they should be regarded as distinct species 
and not variants (Hale 1937, p. 73). Zimmer mentions that specific differences
