A single ovigerous female, about 9 mm. in length, doubtless 

 belongs to this species. It differs, however, from Borradaile's 

 brief description in possessing six distinct segments in the carpus 

 of the second peraeopods. The presence of strong supraorbital 

 spines and the very short rostrum, armed with only a single dor- 

 sal tooth are characters which readily distinguish it from the two 

 preceding species. According to Borradaile the first leg is enlarged 

 in adult males. 



■'I,';' Port Blair, Andainans. S. Kemp. One. 



The specimen was found at low water on the coral reef in 

 North Bay and was, when living, rather conspicuously mottled. 



Thor maldivensis was described from Minikoi, the Maldives 

 and Salomon Atoh.

This species is not very abundant in Port Blair harbour. The 

 majority of the specimens obtained were taken at Corbyn's Cove 

 North, not far from the entrance to the harbour, living in a fucoid 

 weed washed by the waves. All the individuals taken in this 

 situation were of a dull olive-brown colour closely resembling that 

 of the sea- weed. 



The collection includes many ovigerous females, an unusually 

 large specimen being 21 mm. in length. 



'fo^ Port Blair, Andamans. S. Kemp. Many. 



Genus Phycocaris, nov. 



Carapace with supraorbital and antennal spines; antero- 

 lateral (pterygostomian) spine absent. Lateral process of anten- 

 nular peduncle spiniform ; upper flagellum uniramous. Mandible 

 with incisor-process, but without palp. Third maxillipede with 

 exopod. Neither epipods nor arthrobranchs at base of first four 

 peraeopods. Carpus of second peraeopods composed of two seg- 

 ments. Endopods of second to fifth pleopods very large in female, 

 small and slender in male.
