comatulids. Moreover the joints between the assicles of the division series in 

 the species of Comatella though never pseudosyzygies, are often so close as to be 

 distinguishable externally.

Habitat. — China Sea. 



Remarks. — In appearance this curious animal resembles such species as 

 Comantheria briareus, but the arm structure is that of a typical CapiUaster.

Localities.— fi-as^ of the Terrihks ; if /„//,,„„, .__One rather small, though 

 apparently mature, specimen. 



Off Colombo Light House ; i%^ fathoms.— Fom medium-sized and small examples, 

 each with about sixty-five arms. 



Off the north-eastern coast of Ceylon {A° 51' 30" N. lat., 81° 11' 52" E. long.); 

 28 fathoms. — Two rather small specimens. 



Other Records.— Phihppine Islands; Cebu ; Moluccas; Banda ; Sunda 

 Mands; Singapore; North Male, Maldives. 



Depth.— Littoral, and down to 74 fathoms. 



Remarks.— A large series of specimens of this species from Singapore and 

 the Philippine Islands was available for comparison with the above recorded 

 examples; there appear to be no constant differences correlated with locality; 

 though usually perfectly smooth, in some of the Philippine examples the elements 

 of the division series have somewhat projecting distal ends as in the sjjecimen 

 from Banda figured by Carpenter. This seems to be a rather uncommon condi- 

 tion in this form, though characteristic of the other species of the genus. Super-
