The egg-sacs lie in segment xiil. 
The spermathece are in segments vi. and vii., 11 and 17 in 
each. 
The diverticula as in P. Everetti. 
The spermiducal glands are large and compact; they are 
limited to one segment, but the bounding septa are bulged 
out to make room for the gland. The duct has no terminal 
muscular sac. 
Hab. Tamburungare, Kina Balu, Borneo, at an altitude 
of 7700 feet. 
Pericheta merabahensis, sp. 0. 
The length of this worm is 204 millim. and the diameter 
4millim. It has 146 segments. ) 
The body-wall, when preserved, is extremely soft and partly 
transparent. The species shows a tendency to individual 
variation, especially in the size of the ceca, one individual 
having none. Out of twenty-nine adults one was deformed, 
having the right.male pore in the normal position in segment 
xviii. and the left at xv., with the spermiducal gland corre- 
spondingly displaced. 
The clitellum extends from xiv.—xvi., and is without sete. 
The first dorsal pore lies between segments x1./xii. 
The male pores are close together and rather tumid, but no 
genital papille are present. 
The gizzard lies in segments vill. and 1x. 
The intestine commences in segment xv. 
There are ceca in segment xxvi., which are quite small and 
insignificant. In some specimens they are most obscure and 
nearly empty; while one individual had apparently none 
whatever. 
The hearts are in segments xi.-xill. 
The septa v./viil. are much thickened. 
There are three pairs of spermathece in segments vi., vii., 
and vill. The pouch is of considerable size, and the duct 
short and stout. The diverticulum is single and small, and 
attached to the duct by a long delicate tube. 
In segments x., xi., and xii. are three pairs of sperm-sacs, 
approximately the same size. 
The ovaries lie in segment xiii. 
The spermiducal glands are tongue-shaped, cut up into 
loose lobes. There is a large muscular sac in segment xviii., 
narrowing into a duct in xix. The glandular part extends 
a the posterior end of segment xix. to the commencement 
of xxil. 
Hab. Padas Valley, N. Borneo.
