The species marked with an asterisk are common to other 

 regions. The Malayan region, according to M. Perrier, in spite of 

 some secondary differences ought to be considered not only in the 

 matter of the Asteriadse, but in other departments, as forming 

 one vast region of zoological geography. The most intimate 

 affinities unite the faunas that belong to its different portions, 

 to which, however, he thinks more properly the term Pacific 

 Region should be applied. 



The Indian species, properly speaking, are so few in number 

 that they may be inserted here for comparison. 



ASTERIAS RUBENS, L. 



Pentaceros affinis, Mull, and Trosch. 

 P. regulus, Valenc. 



P. REINHARDTII, Liitk. 



P. verrucosus, Mull, and Trosch. 



P. WESTERMANNI, Liitk. 



Dorigona longimana, Perrier. 



ASTROPECTEN EURY ACANTHUS, Liitk. 



M. Perrier says that it is sufficient to cast one's eyes on this list 

 and to compare it with the preceding to see that the Malayan and 

 Indian regions differ completely in starfishes. If the genera are 

 nearly allied, the species are absolutely distinct. 



Echinoidea.— Hardly perhaps connected with the fisheries, 

 but still deserving mention, are the Sea-urchins, &c. The Straits 

 of Malacca are essentially the home of the sea-urchin known 

 as Diadema setosum, an urchin of great beauty in the water 

 from its spines five and six inches long, straight, stiff and black, 

 like hairpin wire. When the tide is out the ledges of rock 

 are seen to be simply covered with them as closely as they can lie. 

 The natives call them Bulan-babi or round pig, and they regard the 

 formidable spines with much dread. Next in numbers is Temno- 

 pleurus toruematicus, which was frequently brought up when 

 dredging, together with a Salmacis. The following species have 

 also been identified : —
