NO, 3666 CRUSTACEA—TIRMIZI AND MANNING 25 
The small specimen of this species from Astola Island has a faintly 
sinuate inner margin on the uropodal endopod, as in the specimens 
from Madagascar reported by Manning (1968b). 
DistriBuTion.—Indo-West Pacific, from Vietnam, Australia, and 
the western Indian Ocean. It has not been recorded previously from 
West Pakistan.

MatTEriAt.—1<’, 30 mm; 19, 24 mm (in 2 lots); off Karachi; University of 
Karachi. 
Draenosts.—Anterolateral angles of rostral plate rounded or sub- 
acute, anterior margins straight, ocular scales small, erect; carinae of 
sixth abdominal somite swollen, each usually with apical tubercle; 
telson broader than long, dorsal surface ornamented with numerous 
small spinules and tubercles; all carinae of dorsal surface inflated; 
anterior dorsal carinae smooth dorsally, spinulose laterally; carinae 
of marginal teeth very spinulose dorsally; 3 pairs of marginal teeth 
present, submedians with movable apices; submedian and interme- 
diate teeth blunt, broad, lateral teeth sharper; numerous small sub- 
median and 2 sharp intermediate denticles present, inner larger and 
set at level of apex of intermediate tooth, outer more recessed an- 
teriorly ; submedian teeth lacking well-marked ventral carinae; uropod 
with full complement of setae; outer spine of basal prolongation of 
uropod broader and slightly longer than inner. 
Cotor.—Almost completely faded; there are traces of black spots 
in no particular pattern on the dorsum of the male. 
Discussion.—Manning (1967b) noted that specimens of this 
species showed two different patterns of dorsal spinulation on the 
telson. The specimens reported herein are of the form with numer- 
ous small spinules approaching the condition found in G. spinosus 
Bigelow. The well-developed intermediate teeth of the telson will 
immediately distinguish this species from G. spinosus, to which it 
is closely related. 
The full complement of setae on the uropod will distinguish this 
species from G. demaniz (discussed below), in which most of the inner 
margin of the uropodal endopod and exopod is smooth and devoid 
of setae. 
The larger male specimen differs from the female in having all of 
the carinae of the telson more inflated and in having fewer, blunter
