Manningia Seréne, 1962 
Diacnosis.—Cornea bilobed, outer margin of eye longer than 
inner; rostral plate pentagonal; carapace unarmed, cervical groove 
indicated on lateral plates only; raptorial claw stout, dactylus with 
4 teeth, propodus fully pectinate, carpus with 2 dorsal spines; fifth 
and sixth abdominal somites with carinae; telson with median carina 
and 5 pairs of lateral carinae on dorsal surface; submedian teeth of 
telson approximated, submedian denticles absent; 2 intermediate 
denticles present; intermediate and lateral denticles each flanked by 
sharp ventral denticle; basal prolongation of uropod terminating in 
2 spines, with spinules on inner margin. 
Typr-species.—Pseudosquilla pilaensis de Man, 1888. 
Discussion.—Manning (1967a) reviewed the known species of 
Manningia and pointed out that the specimen reported from the 
Gulf of Aden by Nobili (1906) and others probably belonged to a 
new species. Because of the fragmented nature of the single specimen 
known from there, the species was not described. Since that study 
was completed, additional specimens from the Red Sea have been 
studied by L. B. Holthuis (1967b), who has described species as new. 
A single specimen of this species is reported herein from West Pakistan. 
Manningia pilaensis (de Man), recently recorded from Bombay by 
Chhapgar and Sane (1968), could also occur off West Pakistan. 
Two other species of Manningia have been recorded from localities 
in the Indo-West Pacific region, but neither of these are known to 
occur in the western Indian Ocean. Manning (1967a) provided a key 
to all of the species then known.
