Three individuals were obtained, of which the largest is 32 miu. long 

 and 24 mm. broad. 



Its occurrence in the Mergui Archipelago extends the range of the 

 species, which was previously known only from the Philippines to China, 

 Japan, and the Sandwich Islands, and Dutch East Indies. Later it has, 

 however, been recorded from the Mozambique coast. 



ASTEROIDEA. 



Xineteen species of Asteroids were collected, including no new species 

 but many new records for the ^Mergui Archipelago, and, in some cases, for 

 the Indian Ocean. These collections have therefore not borne out Dr 

 Anderson's belief of " a reasonable expectation that a number of new species 

 may ultimately be found in the Mergui Archipelago." Dr Anderson ' 

 collected nine species, of which three were new. Of these nine species only 

 four occur in the present collection, or, at the most, five, if we can include 

 Astropecten JTcinprichii, should it prove to be the same as A. niauntuoius. 

 None of Anderson's new species are included in our collection. The total 

 number of Asteroids known from the Mergui Archipelago is therefore 24, 

 or possibly 23. In addition, a species of Cidcita was frequently seen on 

 the coral reefs, but no specimen reached this country. 



The Asteroids in the present collection are as follows : — 



1. Archaster typictui, M. & T. 



2. Graspidaster hesperus (M. & T.), Sladen 



3. Astropecten mawitianns, Gray. 



4. Astropecten zebra, Sladen. 



5. Astropecten poli/acanthics, M. & T. 

 G. Luidia fordfer, Sladen. 



7. Luiclia macnlota, M. & T. 



8. Goniodiscus articulatm (Linn.), Liitkeu. 

 9 Stellaster incei. Gray. 



10. Anthenea jlavcscens (Gray), Perr. 



11. Anthenea pentagomda (Lam.), Perr. 



12. Peiiiaceros granulosus, Gray. 



13. Pentaceros lincki (de Blainv.). 



14. Pentaceros superhus, Mobius. 



15. Pentaceros gracilis, Liitken. 



16. Palmipcs rosaccns (Lam.), Duj. & Hupd.
