1896. ] FROM THE SANDWICH ISLANDS. 195 
to the genus Pericheta. I am much indebted to Dr. Sharp, and 
also to Mr. Perkins for his careful preservation of the specimens. 
Our knowledge of the Earthworms of the Hawaiian Archipelago 
is at the present time exceedingly limited: four species form the 
entire list; and of these Pericheta corticis of Kinberg', though 
undoubtedly a Pericheta, or at least a Perichetid, is quite unrecog- 
nizable as a species, while Hypogewon havaicum of the same 
naturalist is believed by Rosa? to be merely Allolobophora putris, 
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. Rosa’, and fully described from material existing in the Vienna 
Museum, as Pericheta hawayana. The second, which is not 
perhaps so certainly a distinct species, I have myself described 
under the name of Pontoscolew hawaiensis in my recently published 
* Monograph of the Order Oligocheta’ (p. 660). 
In the present communication I have three new Hawaiian species 
to add to this list; and I have also to record the oceurrence in 
those islands of a few widely distributed forms. The entire list of 
Earthworms now known from the Hawaiian Archipelago, excluding 
only the unintelligible Perichata corticis, is as follows—the species 
peculiar to the islands being printed in Clarendon type :— 
Fam. LuMBRICcID®. 
(1) Allolobophora fetida. 
(2) Allolobophora putris. 
(3) Allolobophora caliginosa. 
Fam. Prericu xr 2. 
(4) Pericheta indica. 
(5) Pericheta hawayana. 
(6) Pericheta perkinsi. 
(7) Pericheta molokaiensis. 
(8) Pericheta sandvicensis. 
Fam. GeEosconicip®. 
(9) Pontoscolex hawaiensis. 
This will appear to many to be a meagre enough list, especially 
when 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,
