on the last three and first five thoracic somites, and the small number 
of spines on the abdominal carinae. 
DistTRIBuTION.—Indo-West Pacific, from East Africa to China and 
Australia. Kemp (1913) listed two specimens from Karachi. 
Harpiosquilla Holthuis, 1964 
Diacenosis.—Eye large, T-shaped, cornea bilobed, distinctly 
broader than stalk (fig. 13a); ocular scales separate; carapace with 
deep posterolateral excavations; mandibular palp 3-segmented; 
5 epipods present; dactylus of raptorial claw with teeth, upper margin 
of propodus with row of large, erect spines and intervening smaller 
spines or denticles (fig. 12e); lateral processes of next 2 somites not 
strongly bilobed, sinuous, sharp posterolaterally; abdomen broad, 
submedian carinae usually present; telson with apices of submedian 
teeth fixed; basal prolongation of uropod with at most tubercles on 
inner margin. 
Typr-speciEs.—Squulla harpax de Haan, 1844. 
Discussion.—This genus now includes four species, all of which 
occur in the western Indian Ocean. Two of the species, H. harpax 
(de Haan) and H. raphidea (Fabricius), occur off West Pakistan. 
A third species, H. annandalei (Kemp), has been recorded from the 
Gulf of Oman by Chopra (1939), and the fourth species, H. melanoura 
Manning, is known only from Madagascar. 
We have included here an account of a single specimen of H. 
raphidea from East Pakistan from the collection of the Zoological 
Survey Department. 
The two species known from Pakistan may be distinguished by 
means of the following key.
