The spermathece are two pairs and lie in segments viii. 
and ix. Each has a small diverticulum, pyriform i in shape, 
like the main pouch. 
(10) Pericheta vitiensis, sp. n. 
The collection contained a single specimen of a Pericheta 
bearing the label “A/ypogwon, sp. att. Hyp. orthostichon, 
Schm. Viti Ins.” It measures 75 millim. and consists of 
about seventy segments. ‘The colour of the preserved speci- 
men is a brownish yellow, grey upon the clitellum. The 
setee are borne upon a very distinct ridge upon the middle of 
each segment. ‘The clitellum occupies segments Xiv.-xvi., 
ending a little way in front of the posterior “border of the six- 
teenth segment. ‘There are no sete upon the clitellum. The 
male pores are transversely elongated, somewhat curved, slits 
lying upon two glandular-looking areas upon the eighteenth 
segment; between the two pores are about six sete. The 
two pores are 3 millim. apart. ‘The dorsal pores begin 
between segments xi./xii. The spermathecal pores (one 
pair) lie between seoments vil./vili. on a line with the male 
pores. The oviducal pore is single and median upon segment 
XIV. 
The gizzard lies in segments ix., x., the septum dividing 
those segments being absent. From the septum which 
bounds the eiazzard anteriorly a number of muscular bands 
are given off which are attached to the dorsal parietes. There 
is only one very clearly defined septum in front of this one ; 
behind the gizzard are four rather thickened septa. The 
large intestine commences in the fifteenth segment, and there 
are a pair of ceeca not quite in the usual position; they appear 
to belong to segment xxiv. The dorsal vessel is single, and 
from about the thirtieth segment there are well-developed 
septal glands arising from the posterior septum of the seg- 
ments, ‘and in many cases forming a continuous mass lying 
above the dorsal vessel. 
The sperm-sacs are in segments x1. xil.; each sperm-sac 
sends up a narrow tubular process which approaches its fellow 
in the middle dorsal line ; the arrangement in fact recalls that 
found in Pericheta Vi aillanti, where, however, the processes 
become fused, thus forming an arch round the intestine. I 
found one pair of testes in segment xi, attached to the front 
wall of the segment. ‘The funnels of the vasa deferentia, of 
which there are also only a single pair, open in the neigh- 
bourhood of the testes ; the septum dividing segments x./x1. 
seems to be made up of two layers, between which the tunnel
