Read 4th June, 1908. 
Tue Polycheta, of which this is the first part of a description, are contained in three 
collections from different parts of the Indian Ocean. The first two were made by 
Mr. J. Stanley Gardiner, F.R.S., of Caius College, Cambridge, the first in the Maldive 
Archipelago in the year 1899 and the second in the Seychelles and Chagos groups in 
1905. Incorporated with these is a third made by Mr. Cyril Crossland, M.A., at Zanzibar 
in 1901-2. Partof the Eunicide and the Chetopteridze from Zanzibar and the Maldives 
have been described by Crossland*, but absence from England has prevented him from 
prosecuting the work. ‘The Annelids from Zanzibar were received late and only a single 
species is here noticed. The noteworthy feature of this assemblage of Amphinomids 
is the wealth of new species, though this might only be expected in the neglecied 
state of the group. Previously collections from the Indian Ocean have only been made 
at Ceylon. In Willey’s description of the Annelids collected by Professor Herdman, 
only two Amphinomids are mentioned. Of these it is interesting to observe that the 
widespread Chleia flava is absent from this extensive collection, though the genus is 
represented by four species. The re-discovery of C. fusca, a single specimen of which 
was dredged by the ‘ Challenger’ off the Moluccas, is also a noteworthy feature. 
A number of examples of Eucarunculata grubei, a genus and species described in 1906 
by Malaquin and Dehorne from the Malay Archipelago, were also obtained. 
The Polycheeta of the Red Sea have now been very thoroughly described by Gravier. 
In a new species of Amphinome from the Maldives we have a very close resemblance 
to A. djiboutensis, Gravier, though the Red Sea collections were, as a whole, poor in 
Amphinomids. 
Genus CHLCIA, Savigny. 
The Chleias of this collection belong to the group of C. fusca, which possesses “ bifid 
bristles of three kinds, viz.: (a) very slender and attenuate, (0) with stout short tips, 
and (¢c) with longer tips serrated externally on the longer limb.”
