II.—On Two New Species of Pheretima 
from Borneo. By W. Michaelsen, Hamburg. 
The following descriptions are based upon a small lot 
of Earthworms collected by Mr. T. C. Moulton, Director of 
the Sarawak Museum, at Mt. Poi, in Sarawak, North-west 
Borneo. The first species especially, which I name in 
honour of its collector, is of great interest on account of 
its curious habitus, which is not at all that of a Pheretima 
in general. 
Pheretima Moultoni, Michaelsen, n. sp. 
Loc .-—Borneo, Sarawak: Mt. Poi, 4000 ft. high, “curled 
up on a leaf” ; T. 0. Moulton leg. 
Present 3 mature specimens. 
External Characters .—Dimensions : Length, 45-55 mm.; 
greatest thickness, 2-2J mm.; number of segments about 
98-100 (hinder end of all specimens regenerated). 
Head tanylobous, prostomium small. Hinder appendix 
of prostomium nearly as broad as the prostomium, with 
parallel borders, which get somewhat less distinct at their 
hinder end. 
Habitus nearly that of a terrestrial Planarian. 
Body flattened ventrally, and even somewhat hollowed 
in the ventral median line. 
Colour: Dorsal part of body-wall showing a very 
characteristic pigmentation, consisting of small dark 
violet-brown, nearly black, spots. Around the dorsal pores, 
which are distinguished as small circular white points 
{viz., intersegmentally), a lot of such dark spots join in 
order to form a large irregularly bordered figure. At the 
anteclitellar part of the body these intersegmental figures 
get relatively larger and tend to join each other, and are 
forming there a complete moniliform median dorsal stripe. 
In the meantime the scattered spots diminish in number, 
and at about the tenth segment they vanish altogether. 
The median dark stripe is tapering from about the sixth 
segment forward, and is ending in a foremost, more or 
less isolated spot at the intersegmental furrow 1-2 or 2-8. 
The largest number of dark spots upon one segment is 
about twenty, without including the larger dark figure on 
the median dorsal line. The prime colour of the body-wall 
is light yellowish-grey.
