[Plates XX. & XXI.] 



Although a considerable number of species of the large 

 genus Perichceta have been described from the Malay Archi- 

 pelago by Horst, Rosa, Beddard, and mj'self, yet none have 

 been collected, so far as I am aware, on the island of Celebes ; 

 at any rate, none are recorded in Beddard's monograph. I 

 was therefore very glad to have the opportunity of examining 

 a small collection from this island and from Jampea, due 

 south of it, made by Mr. H. Everett and presented to the 

 British j\Iuseum, and placed in my hands for identification 

 by Prof. Bell, to whom my best thanks are due. 



The twelve worms which form the collection fall into at 

 least six groups, none of which agree with any species hitherto 

 known. As so frequently happens, some of these new species 

 are represented by one specimen. 



For the more ready comparison with already existing 

 species, I append to each description of the anatomy of the 

 individual a summary of what 1 regard as the characteristic 

 features, in the form of a diagnosis. Such a diagnosis is of 

 no value till other specimens are fomid ; but I have much felt
