One denuded test dredged off Pulo Brani, Singapore ; there is also another test of this species in the Raffles Museum collected at Singapore. Distribution. Ranges over the entire circumtropical littoral zone, including the West Indies, Cape Verd Is., Mediterranean, and Indo-Pacific as far east as the Society and Sandwich Islands ; it is not recorded from Australia. M . de Loriol does not agree with Prof. Bell in uniting the Brissus unicolor and carinatus of Alexander Agassiz into one species; he bases his distinction on characters admittedly variable in different individuals of the same size and in the same individual at different stages of growth. I have therefore, with some hesitation, followed Professor Bell in this respect; but since Dr. Loven has shown that Klein's Brissus unicolor is probably identical with 3Ietalia maculosa aud certainly not a true Brissus at all, it follows that the name of B. carinatus should be retained for this species, which is undoubtedly the same as that referred to by Leske as Spatangus brissus latecarinatus and renamed carinatus by Graelin. In our example the peripetalousfasciole is normal for Eastern forms, having two re-entering angles in each anterior interambulacrani, and in the odd interambulacram it forms a deep angle as in Leske's figure of Spatangus brissus latecarinatus. The subanal fasciole is reniform, and there are 5 pedicellar pores on each side of subanal area. Measurements. Length. Trans, diam. Ant. petal. Post, petal. Height.

Seventeen species of Asteroids w ere collected, several of which were, however, represented by single or fewr individuals; five species were found in the immediate neighbourhood of Malacca, but these were all specifically distinct from any found at Singapore and 3 out of the 5 were very abundant. This is worth noting, since the four species of Echinoids collected at Malacca were common |
