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. 
9251 Port Blair, Andamans. 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 Atoll.

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.

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.
