Locality. A single specimen dredged in 10 fathoms off Malacca. 



Distribution. Malacca to Australia. 



A single specimen was brought to Europe in 1837 from the 

 Straits of Malacca by Eydoux and Souleyet (v. Perrier), hut the 

 authenticity of the locality has been since doubted ; it is interesting 

 therefore to have the opportunity of confirming the original 

 statement. 



This specimen appears to be identicalVith Australian examples 

 in the British Museum; a minute, scanty granulation is present 

 on the superomarginals, the inferomarginals being smooth ; in 

 three of the arms the superomarginals of each side alternate along 

 the arm, especially towards its distal end (cf. Doederlein's figure 

 and also Studer's Dorigona moebii).
