196 MR. F. E, BEDDARD ON EARTHWORMS [Jan. 14, 
It is early, of course, to lay down any general statements; and 
were it not that Mr. Perkins has collected so many species and in 
most cases so many individuals of each species, I should have 
contented myself with a plain description of fact and should not 
have ventured upon comment. It may be permissible, however, 
to indicate the “ Oriental ” facies of the fauna and the absence of 
very peculiar types. The latter statement, in fact, appears to 
hold good generally for oceanic islands, so far as our imperfect 
data enable us to speak. It argues their really oceanic origin and 
their short existence. Even in Kerguelen and Marion Is., which 
are remote from traffic and can hardly have been stocked by human 
means, the one known species, Acanthodrilus kergquelarum, is only 
specifically different from the Earthworms most nearly allied upon 
the adjoining mainlands. And these islands are possibly among 
the most ancient of oceanic islands. 
Allolobophora foetida, Sav. 
Numerous examples of this widely distributed species from 
Halemanu, Kausi. 
Allolobophora caliginosa, Sav. 
Hab. Waialua, Oabu. 
Allolobophora putris, Sav. 
There are a large number of examples of the variety “ arborea” 
(smaller, and with tubercula pubertalis only upon xxix.& xxx.),which 
Rosa believes to be identical with Kinberg’s ‘“Hypogeon havaicus.” 
Its occurrence, therefore, is not a new fact. 
Hab. Molokai, and Kawailoa River, Oahu. 
. Pontoscolex hawaiensis, n. sp. 
Of this apparently new species some 8 or 10 examples were 
collected. 
The Jength of a fair sized specimen is 142 mm; the breadth at - 
the clitellum 4 mm., elsewhere rather less. The number of 
segments is rather more than 210; after the 128th segment is 
an oval swelling upon the body 3 mm. long and commencing about 
90 mm. from the anterior end; this is the structure which has 
been described in other species, and regarded as a growing point. 
This modified region of the body appears to be constant in position; 
this is shown by the following measurements of two individuals:— 
A. Bz 
Length of body in front of “growing region” .... 90 80 
Length of body behind “ growing region”........ 47 40 
The intestine proper appears to begin at the end of the clitellum; 
there is here a distinct circular valve, and the intestine has a 
distinct typhlosole projecting intoits lumen. The calibre, however, 
is not greater. 
The sete of this species are, as in Rhinodrilus, ornamented
