Locality. One denuded test dredged off Pulo Brani, Singapore ; 

 there is also another test of this species in the Baffles Museum 

 collected at Singapore. 



Distribution. Banges 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 

 Metalia maculosa and 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 Gmelin. 

 In our example the peripetalousfasciole is normal for Eastern forms, 

 having two re-entering angles in each anterior interambulacram, 

 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.

II. ASTEBOIBEA. 



Seventeen species of Asteroids were collected, several of which 

 were, however, represented by single or few 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
