NO. 3666 CRUSTACEA—TIRMIZI AND MANNING 35 
Discussion.—Tiwari and Biswas (1952) were the first to show 
that H. harpax (de Haan) is distinct from the larger H. raphidea 
(Fabricius), which is also widely distributed in the Indo-West Pacific 
region. Harpiosquilla harpax differs from H. raphidea in having a 
shorter rostral plate, in lacking the lateral spine on the fifth thoracic 
somite, in having more than one spine or spinule between the major 
spines on the propodus of the claw, and in having the carinae of the 
abdomen less well developed. In H. harpaz the submedian carinae of 
the abdomen are present but they are poorly-defined. 
The petasma is illustrated in figure 13e. The tube process is well 
developed; the hook process has an additional hook-like projection on 
its inner, distal margin. 
DistRIBUTION.—Indo-West Pacific region, from the Red Sea and 
South Africa eastward to Japan. 
Cloridopsis Manning, 1968 
Diacnosis.—Eye small, stalk dilated or margins subparallel, 
cornea broader than stalk; ocular scales separate; carapace rounded 
posterolaterally; mandibular palp present or absent; 2-3 epipods 
present; dactylus of raptorial claw with 5-6 teeth, upper margin of 
propodus pectinate; lateral processes of fifth, sixth, and seventh 
thoracic somites not bilobed, process of fifth somite a broad, curved 
spine; abdomen broad, submedian carinae present; telson with apices 
of submedian teeth fixed; basal prolongation of uropod with at most 
tubercles on inner margin. 
Typr-sprEcies.—Squilla scorpio Latreille, 1825. 
Discussion.—Two species of Cloridopsis occur in the north- 
western Indian Ocean, and both are reported herein from West 
Pakistan. They may be differentiated by means of the key given 
below.
