sex and the lateral tooth though shorter and stouter than in the female is much longer. 

 There are ten to fourteen fine submedian denticles, nine to twelve intermediate and 

 one lateral. The spines on the abdominal somites have the same distribution as in 

 5. leptosquilla and, as in that species, there is no mandibular palp and the dactylus 

 of the raptorial claw bears four teeth including the apical one. 



The preserved specimens show no trace of colour ; the large brown spots on the 

 telson, which are invariably found in 5. leptosquilla, seem to be absent. Wood-Mason 

 remarks that the colour in life is deep pink. 



There are eleven specimens in the Indian Museum registered thus : —

 The carapace is smooth or very feebly rugose and its breadth behind the antero- 

 lateral spines is more than half its median length, including the rostrum. The lateral 

 margin is concave and is produced to a blunt angular point immediately in front of 

 the rounded postero-lateral angles. The median carina is distinct 1 and is anteriorly 

 bifurcated for about one-fifth its length anterior to the well-marked cervical groove 

 (fig. 35). The small mid-dorsal pit is conspicuous, as are also the intermediate and 

 lateral carinae. The rostrum is subquadrate, considerably wider than long ; its lateral 

 margins converge to the rounded antero-lateral angles and the distal edge is truncate 

 or broadly convex. Dorsally it bears a sharp carina in its distal half and a pair of 

 other carinae running close to the lateral margins. 



The cornea of the eye is wider than the stalk and is set obliquely on it; its 

 breadth is clearly less than the whole length of the organ. The ophthalmic somite 

 projects between the base of the eyestalks in the form of a very prominent subquad- 



1 Except in a large male specimen in which it is worn away and obsolescent.
