110 ECHINODERMA OF THE InDIAN MuSBUM, PART VII. 



l'„ is often much larger tlian on the outer, while the adjacent pinnules are 

 reduced. 



The colour in spirits is Hesh colour, the cirri violet ; or, cirri and division 

 series violet, the arms flesh colour, more or less clouded with violet ; or, entirely 

 deep violet. 



Localities. — Port Blair, Andaman Islands (Type Locality)— One specimen. 



Aridamari Islands. — Four specimens. 



Other Records. — Java ; Kwala Cassam, Malay Peninsula. 



Remarks. — Examination of the type of Miiller's Comatnla philiberti , preserved 

 in the Paris Museum, has shown me that it is the same species as that which 

 1 described, from specimens in the Indian Museum collection, as Amphimetra 

 inorfenseni. Miiller's description was not detailed, and the specimen had never 

 been re-examined, so that there was no way of telling even to what genus it 

 belonged until an opportunity oifered of studying it.

Localities. — Poeock Island ; 20 fathoms. — One specimen with twenty arms 

 110 mm. long : three IlBr series are lacking, but the deficiency is compensated 

 l»y the development of three IlIBr series. The seven IIBr series are extra- 

 ordinarily irregular ; one is 8(3-|-4; 5-|-6; 7-|-8), one 2, one 4, the two outer 

 elements united by synarthry, and four are 4 (3-|-4) ; the three IIIBr series are 

 also irregular, one being 1, one 2, and one 4 (3-)- 4), the last two being on a single 

 p().st-radial series, 2 externally, 4 (3-}- 4) externally. 



This example agrees with others from Singapore in the collection of the 

 Copenhagen Museum, and with others from Australia in the collection of the 

 Australian Museum.
