the duct about half-way down ; the form of the diverticiilum is very variable ; it 
may be a short, simple, club-shajied structure scarcely extending to the junction 
of the am])ulla and duct or it may be com 2 :)osed of a cluster of from two to four tubules 
of varied lengths, sometimes somewhat convoluted and anastomosed (varying from 
slightly to almost completely) from the base distally. The component tubules of a 
compound diverticulum may be sufficiently long to extend well beyond the junction 
of the ampulla and the duct. 
The ])rostates are small, narrow, tongue-shaped bodies confined to xviii., 
finely granular ; tlie duct is very short, traversing only the body wall. Although not 
sectioned the external appearance of the prostate leaves little doubt that the glandular 
part has a branched canal system. 
Penial setae present but seemingly all with the tip missing and too damaged 
for examination.

WOODWARDIELLA YOUNGI, sp. nov. 
External fferactera.— Length 3fi0 mni., diameter 9-10 mm. In alcohol the 
colour is mole-grey dorsally, with a greenish tinge on the head end as far back as and 
including the clitcllar segments ; brownish-cream ventrally. Number of segments 225. 
Prostomium proepilobous. 
Dorsal pores commence in furrow G/7. 
Setae widely paired in regular lines, lu front of the clitellum ab = ^ aa ^ > A 
be = = cd ; behind the clitellum ab = jL aa = | be = cd ; at midbody ab = ^ 
aa = I, be = cd ; dd is loss than half the circumference. 
The clitellum embraces segments xiv.-| xviii. (= 4§) and also encroaches 
slightly on xiii. ; the three anterior segments are complete all round ; onxvii. extends 
to the dorsal limit of the genital j>its on each side and then across the ventral portion 
of the segment as a strip immediately anterior of the genital pits ; on xviii. cut away 
like a saddle. Setfe present, dorsal pores absent, interscgmental furrows visible. 
Ventral surface of xviii. glandular generally ; seta a on each side absent ; 
seta b surrounded by a darkened, somewhat eircidar halo of slightly swollen epidermis 
about equal to ab in. diameter ; from these halos the j'^igmentation not so deep 
continues ventrally and finally fades out just beyond a. Male pores could not be 
discerned from an external examination ; dissection demonstrates that they are 
jiaired and open in the immediate vicinity of b. 
The female pores are distinct and paired on xiv. ; they lie one at each end of a 
comparatively wide V-shaped groove just anterior of the setfe ring. 
The spermathecal pores are three pairs in furrows 6/7, 7/8, and 8/9 slightly 
dorsal of 6,
