longa, though the dimensions of his specimen are much 
greater. The spermathecae agree very well with Michael- 
sen’s figures, only their blind end has a more dilated, 
tongue-shaped appearance. . 
Perichaeta tjibodae n. sp. 
Two specimens from Tjibodas (Java), collected by Dr. 
van Bemmelen. 
Among the worms, collected at Tjibodas, there are two 
specimens, which, though resembling in many respects 
P. capensis Horst (— operculata Rosa), cannot, as I be- 
lieve, be identified with that species. The smallest exam- 
ple has a length of about 50 mm.; the largest one is 
incomplete. The colour is olive-brown; the anterior end 
of the body with the clitellum is greyish. 
The cephalic lobe with a broad appendix extending back 
till the half of the buccal segment. Clitellum distinct, 
without setae. Two pairs of spermathecal pores, situated 
entirely ventrally, in the intersegmental grooves VII/VIII 
and VIII/IX; the distance between the pores of one seg- 
ment hardly 11/, times that between the pores of two suc- — 
ceeding segments. The pores of a pair are connected to- 
gether by an indistinct, transverse, glandular area (fig. 7). 
Oviducal pore single on segment XIV; male pores on seg- 
ment XVIII, triradiate, as the mouth of a leech, sepa- 
rated by a deepened area, extending over the segment in 
front and that behind. Setae in a continuous ring, 44 
in number. Eight setae between the male pores. No co- 
pulatory papillae. The spermathecae (fig. 7a) are very 
large; the first pair lie in segment VIII, the second one 
in segments VIII and IX, extending along the total 
length of the gizzard. Each spermatheca consists of a 
large, globular sac with a short excretory duct and of a 
tubular diverticulum , terminating in a small, oval vesicle; 
this diverticulum is curved like a horn and extends along 
the superior half of the main sac. The sac shows a yel-
