some Perichete from the Eastern Archipelago. (a! 
The spermiducal glands extend through ‘three segments. 
Their duct does not terminate in a dilated muscular sac. 
flab. Merabah, N. Boxneo. 
Pericheta sarawacensis, sp. n. 
The length of this species is about 800 millim., the diam- 
eter is 7 millim.; the number of segments is 260. There 
was no pigment in the skin of the preserved specimens. 
The clitellum is as in the last two species. 
On each of segments xix.-xxil. are a pair of papillae, which 
are like those of P. papillata. 
The dorsal pores commence between segments xil. and xiii. 
The intestine has no ceca. 
Septa v./vili. and x./xiv. are thickened. 
The last pair of hearts is in segment xiii. 
The sperm-sacs are in segments x., Xi., and xii. 
The egg-sacs in segment Xiii, 
The spermathece are in segments vi. and vii., about 14 in 
each. ach spermatheca has a single diverticulum. 
The spermiducal glands are rather different, extending 
through three segments. 
This species, as will have been inferred from the descrip- 
tion, is somewhat intermediate between the last two. The 
internal structure is more like that of P. Hverett?, while the 
papille are more like those of 2. papillata, though not so 
numerous. 
Hab. Sarawak. 
Pericheta kinabaluensis, sp. n. 
The length of this species is 150 millim. and the diameter 
9 millim. Number of segments 200. The red coloration 
noticeable in P. Hveretti also characterizes this species. The 
implantation of the setee is marked by white lines. 
The clitellum as in the last species. 
The male pores are separated by sixteen sete. 
On each of segments xix. and xx. is a single median 
papilla. On segment xxi. the left half only of the papilla 
was developed. 
The dorsal pores commence between xi. and xii. 
The gizzard is in segment vill. ‘The intestine has no ceca, 
Septa v./vill. and x./xiv. are thickened. 
The last pair of hearts are in segment xii. 
‘The sperm-sacs are in segments x., xl., and xil.
