1896. ] FROM THE SANDWICH ISLANDS, 203 
But I possess specimens from Hong Kong which cannot be 
distinguished. One of these has four papillw near the male pore 
of one side of the body. It therefore approaches Pericheta 
bermudensis, which has a considerable number of such papille. 
These two species are now hardly to be separated. 
Pericheta sandvicensis, n. sp. 
The largest example of this species measures 100 mm. in length, 
and has 105 segments. 
The dorsal pores commence xi./xii., and are visible on the 
clitellum. 
The seta-formula is the following :— 
lip sf XII. XVI. 
21 33 52 53 
The setz of the first two segments are small; those of the next 
four are stronger, after which they again diminish. The sete on 
either side of the median ventral line are not longer than those 
elsewhere. 
The clitellum occupies segments xiv.—xvi., and has no sete. 
The male pores are separated by 18 setw. They were in most 
of the specimens very prominent. 
There are no genital papille. 
The first septwm divides segments .y./vi.; this and the one 
which follows are very stout, and bound to each other by 
numerous muscular threads. The septum vii./viii. is not so thick. 
The next two, as in other VPerichete, are absent. After the 
gizzard are two strongest septs; to the first of these the hinder 
part of the gizzard is attached by at least five muscular straps. 
The alimentary canal presents no character of any particular 
interest. 
The last heart is in segment xiii. 
The sperm-sacs are in segments xi. and xii. The sperm-reser- 
voirs of segment xi. are much larger than those of segment x. 
The spermiducal glands are much incised, and occupy about 
three segments. The duct is long and curved, and is without a 
terminal sac. 
The spermathece are two pairs in vii. and viii. The pouch has 
not a very long duct. The diverticulum is not very long ; it is 
bent often in a zigzag fashion, and does not terminate in a suddenly 
dilated extremity.

Remarks.—The only species with which it would be possible 
to confuse the present are Pericheta annulata and Pericheta 
japonica, In the latter, however, the male pores are described by 
Horst’ as lying upon aJ-shaped groove, which extends on to 
segment xvii. In the former, according to the same author, the
