to the genus Perichmta. I am much indebted to Dr. Sliarp, and 

 also to Mr. Perlsins for his careful preservation of the specimens. 



Our knowledge of the EarUiworms of the Hawaiian Archipelago 

 is at the present lime exceedingly limited: four species form the 

 entii-e list ; and of these Perichcfla corticis of Kinberg ', though 

 undoubtedly a Perichwta, or at least a Perichfetid, is quite unrecog- 

 nizable as a species, while Bypoyceon havaicum of the same 

 naturalist is believed by llosa " to be merely Allolohoplwra putrid, 

 a widely spread species which has been " introduced " into many 

 extra-European countries. Two species, however, which have 

 been sufficiently described for identification, appear to be peculiar 

 to the Sandwich Islands. The first of these was made known by 

 Dr. Eosa^, and fully described from material existing in the Vienna 

 Museiun, as Perichceta liawayana. The second, which is not 

 perhaps so certainly a distinct species, I have myself described 

 under the name of Pontoscolex hawaiensis in my recently published 

 • Monograph of the Order Oligocliasta' (p. 660). 



In the present communication I have three new Hawaiian species 

 to add to this list ; and I liave also to record the occurrence in 

 those islands of a few widely distributed forms. The entire list of 

 Earthworms now known from the Hawaiian Archijielago, excluding 

 only the unintelligible Pcricha'ia corticis, is as follows — the species 

 peculiar to the islands being printed in Clarendon type : —

This will appear to many to be a meagre enough list, especially 

 wlien contrasted with the rich and peculiar insect, molluscan, and 

 avian fauna of' the same islands. But it is a long list when 

 compared with those of the Earthworms of other oceanic islands, 

 from very few of which have undoubtedly indigenous forms been 

 secured.
