Echinoidea and Asteroidea from Mergui Archipelago. 25 



John Malcolm to Charlotte Islands, 18 fathoms, coarse sand ; XXV., 

 Gregory Group, 4 to 14 fathoms, sand and shell ; XXIV., Cat and 

 Kitten, 12 fathoms, rock and sand. 

 All small specimens, the largest being 38 mm. in diameter. In the largest 

 the spines are tipped with violet ; the smaller ones have them entirely white. 

 Height, 18 and 20 mm. Diameter, 37 and 38 mm. 

 Recorded from the Red Sea, Mozambique, and Ceylon, to the Philippines 

 and Australia; and from King Island, Mergui Archipelago, by Dr Anderson. 



10. Salmacis globator, Bell. 

 Bell, P.Z.S. (1880), p. 431, pi. xli. figs. 2, 3, and 8. 



Localities. — XVI., Alligator Rock, 8 to 18 fathoms, rock and sand ; XXII. 

 Hastings Harbour, St Luke's Island, 15 to 20 fathoms, sand and shell. 

 These two specimens agree in all respects with F. Jeffrey Bell's description 

 and figure of S. globator f3. There can be no doubt as to the identity of the 

 Mergui specimens, and the only difficulty that confronts one is the synonymy 

 of the species (see F. P. Bedford, P.Z.S. (1900), p. 282, pi. xxii.). The 

 primary spines are greenish-white and encircled with narrow bright red bands 

 at irregular intervals ; on the actinal surface they are more numerous and 

 longer, attaining a length of 10 mm. around the actinostome ; they are 

 flattened at the tips. 



Height, 41 mm. 36 mm. 



Diameter, 59 mm. 57 mm, 



Actinostome, 15 mm. 16 mm. 



Professor Bell's Salmacis alexandri (S. globator a) (loc. cit.) is not 

 represented in this collection. 



Distributed from Singapore to the east coast of Australia, and possibly 

 in the Korean Straits.

 A. Ag., Rev. Ech., p. 477. 



Localities. — VIII., Port Maria, Elphinstone Island, 4 fathoms, sand ; XX., 

 High Island, 5 fathoms, sand and rock ; XXV., Gregory Group, 4 to 14 

 fathoms, sand and shell. 

 The median tracts of the ambulacral areas are scarcely bare except in the 

 largest specimens. 



Not previously recorded from the Indian Ocean, but known from the 

 Philippines, Japan, and the Sandwich Islands.
