Family MEGASCOLECTD/IT 
Subfamily M EGASCOLECIN^. 
Genus DIGASTER E. Perrier. 
DIGASTER LONGMANI. sp. aov. 
External Characters. — Length about 520 mm. ; diameter ])ehiiid the clitellum 
about 18 mm, in front 20 mm., but dimensions difficult to determine accurately 
owing to distortion and swelling of tlie specimen. Colour in formalin ; Behind the 
clitellum light mole-brown, in front deeper mole-brown ; clitellum very dark brown. 
Number of segments about 315 ; segments v.-xiii. biaimular, iii. and iv. faintly so ; 
vii.-xiii. have also an additional less well-defined annulus lietween the main one and 
the posterior furrow ; iii.-vii. show more or less faintly defined annular rings, one in 
front of, one behind, the principal anmdus. 
Prostomium proepilobous. 
Dorsal pores begin in furrow 5/6. 
Setpe widely paired. In front of the clitellum ah = ;j- aa = h be = | cd ; behind 
the clitellum ah -= i aa = J be = f ed ; at midbody ab = \aa ^ <\hc = eel ; 
dd is greater than half the circumference. The setae are very difficult to discern on the 
pre-clitellar region except on a couple of segments immediately preceding the 
clitellum. 
The clitellum is well developed, complete all round, and embraces segments 
xiv.-xviii. (=5). The intersegmental furrows are visible, dorsal pores absent, setae 
(except a and b on xviii.) present. 
Male pores paired on xviii., in form of transverse slits lying within, and almost 
as long as, ah ; lips tumid, cream in colour. The left pore is excentrically placed on 
a somewhat ovate papilla with uncertain boundaries which extends a little beyond 
ah dorsaily and ventrally, })laced rather nearer the ventral and posterior boundaries.
