206 MR. F. E. BEDDARD ON EARTHWORMS [Jan. 14, 
I give segment vi. instead of y. since I did not count the sete 
with accuracy upon the latter. The sete towards the ventral side 
are slightly more crowded than laterally, but there is no very 
marked difference in size; neither is there any very great variation 
in size from segment to segment. 
The clitellum occupies the whole of segments xiv.—xvi.; it has 
no sete. 
The male pores are separated by 12 sete. 
There are no genital papille. 
Between the spermathecal orifices are 30 sete. 
There are no septa that can be spoken of as specially thickened. 
The gizzard seemed to me—contrary to what is the rule with 
the genus—to only occupy a single segment. At any rate, on the 
right-hand side of the body a septum passes forwards from the 
hinder margin of the gizzard, to be attached close to the orifice of 
the second spermatheca of that side of the body. The intestine, 
commencing in the fifteenth segment, is very sharply marked off 
from the preceding cesophagus by its black colour (due of course 
to contained earth), the cesophagus being yellowish white. The 
intestinal ceca are peculiar and serve to differentiate the species. 
Jt is well known that Pertcheta hilyendorfi, P. sieboldi, and 
P. musica possess as a rule, or occasionally, 6 of these ceca on 
each side of the body, arising, however, one above the other in the 
same segment. The present species is not so amply provided as 
are those to which I have just referred; but it has three ceca on 
each side, of which the upper is the larger. 
The last heart is in segment xiii. 
The sperm-sacs are large and occupy the available space of 
segments xi., xil.; they also extend into x. The sperm-reservoirs 
(in X., Xi.) are small. 
The spermiducal glands extend through segments xvii.—xxi. 
They are much incised and quadrangular in form. The duct 
communicates with the exterior through a large bursa copulatriz. 
The globular spermathece are in vii. and viii.; they open, 
however, between vii./vil. and viii./ix.; their duct is short ; there 
is a long coiled diverticulum rather longer than the pouch, ending 
in a dilated extremity. 
Hab. Barbados. 
PERICHATA TRINITATIS, n. sp. 
This is a stout Pericheta measuring 150 mm. in length and 
consisting of 100 segments. 
The sete upon segments vi—ix. appeared to be larger than 
those on the segments following. On the seventeenth segment 
(from the stripped-off cuticle) I counted 45 sete. There are 20 
between the male pores. 
The dorsal pores appeared to commence on xi./xii. 
The clitellum occupies segments xiv.—xvi. 
The male pores are very conspicuous and surrounded by circular 
wrinkles of the integument.
