have been recorded from the northwestern Indian Ocean, and two 
of these occur off West Pakistan. The third species, P. spinosissima 
(Pfeffer, 1888), has been recorded from the Red Sea by Ingle (1963) 
and could be expected to occur off Pakistan.

Description.—Anterior margin of ocular scales sinuous, scales 
produced laterally into acute lobes; eyes usually extending beyond 
end of basal segment of antennular peduncle; cornea subglobular; 
rostral plate sharply trispinous, median spine slenderer and longer 
than laterals; anterolateral margins of lateral plates of carapace con- 
cave, anterolateral angles acute but rounded; mandibular palp 2- 
segmented; dactylus of claw (fig. 5c) lacking basal notch on outer 
margin; first 4 abdominal somites almost smooth, at most marked by 
obscure lateral grooves; fifth abdominal somite with pits arranged in 
2 rows on either side of ridge separating the smooth median portion 
from irregular lateral portions of somite; carinae of sixth abdominal 
somite and telson covered with short hairs; distal margin of telson 
(fig. 5d) divided into 2 halves by long, narrow, median fissure, distal 
margin of each half with 4 teeth or lobes, submedians with movable 
apices; several small submedian denticles present and 1 denticle 
present between each of remaining teeth; dorsal surface of telson with 
3 bosses (fig. 5d) median triangular, external bosses on each side
