Records of the Indian Museum. [Voi,. XXIV, 



The species is recorded from Tongatabu (Dana), Tahiti (Stimp- 

 son), the Bonin Is. (Balss), Christmas I. ? (Caiman), the Noord- 

 wachter Is. and Pulo Edam in the Bay of Batavia (de Man), the 

 south coast of Arabia (Balss) and from numerous localities in the 

 Red Sea (Nobili, Balss, Tattersall). The species is apparently 

 always found in association with madrepore corals. 



Coralliocaris venusta, sp. nov. 



The rostrum (text-fig. ioo) reaches to the middle or end of the 

 second segment of the anteunular peduncle and is directed slightly 

 downwards. In dorsal view it is broad at the proximal end and 

 is dorsally carinate throughout its length ; in lateral view it is very 

 slender. In the male there is a single dorsal tooth placed a little 

 in front of the middle point; in the female there are two teeth, the 

 foremost very small, both situated in the anterior third. On the 

 lower border in each specimen there is one small tooth placed close 

 to the apex. 



The lower angle of the orbit is acute. There is a strong 

 antennal spine, but the hepatic is absent. 



The antennular peduncle reaches to three-quarters the length

of the antennal scale. The basal segment is broad. In the female 

 the lateral process extends as far as the articulation between the 

 second and third segments and the terminal spine of the outer 

 margin reaches the middle of the third segment ; in the male the 

 spines are shorter. The outer margin of the antennal scale is 

 almost straight, terminating in a spine which does not reach the 

 end of the lamella. 



The third maxilliped (text-fig. 101a) is short and stout and does 

 not reach the end of the merus of the first peraeopods. The exopod 

 reaches the tip of the endopod. The antepenultimate segment is 

 shorter than the two distal segments combined. The penultimate 

 segment is scarcely longer than broad and is a little longer than 

 the ultimate. The ultimate is much narrower than the penulti-
