Differential Characters. — Comatella maculata is a small species 



with twenty arms, or somewhat fewer, about 80 mm. to 100 mm. 



long; the cirri are small, though numerous, and possess not more 



than twenty segments, 



Australian Record. — Bo wen. 



Range. — Northern Australia to the Maldive and Laccadive 

 Islands, and South-eastern Africa. 



Remarks. — The type specimen, which I examined while in 

 London, resembles very closely the specimen from Bowen in the 

 collection of the Zoological Museum at Copenhagen, described in 

 my report on that collection. 



Subfamily COMACTINIIN^. 



Genus C O M A T U L A, Lamarck. 



Comatula, 1816, Lamarck, Hist. nat. des aniniaux sans vertebres 

 vol. 2, p. 530 {Comatula Solaris, sp. nov.). 



Differential Characters. — In Comattda the elements of the IBr 

 series and the following division sei'ies (when present) and the 

 first two brachials are united by wliat appears to be a true syzygy, 

 tliough in reality it is a modified form of the more common 

 synarthry or bifascial articulation. There are ten arms, except 

 in three species, two of which have twenty and the tljird usually 

 ten, but sometimes eleven or twelve. The cirri, which are often 

 absent in the adults, are perfectly smooth dorsally without dorsal 

 spines or ridges. The segments of the genital pinnules are short 

 .and very broad. 



Range. — Comatula ranges from the Andaman Islands, Java 

 and Singapore, including the whole of Austx'alia, to Celebes, the 

 Philippine Islands and Hong Kong. 



A closely allied genus, Comactinia, represents it in the Carildjean 

 Sea.
