The ovisac extends backwards into segment ix; as usual it 
encloses the spermsac. It was mostly occupied, in the specimens 
examined, by discrete yolk granules; a cluster of young ova was 
seen in segment viii, neither at the anterior nor the posterior end 
of the sac. The female funnel, oviduct, and aperture were not 
identified. 
The spermathecae are ovoid sacs, confined to segment v; 
their long axis is mainly longitudinal, but directed somewhat 
downwards as well as backwards; they take up nearly the whole 
length of the segment in a longitudinal direction. They are 
thin-walled and, in the examples investigated, contained sperma- 
tozoa and granular matter There is no prominent peritoneal 
investment. The duct leaves the ventral surface of the ampulla ; 
it is narrow, straight, and as long as the ampulla is high. Its 
lining epithelium is cubical. The aperture is near the anterior 
border of segment v. 
Fam. TUBIFICIDAE.

Limnodrilus sp. 
Sona Sar Lake, Kashmir, 12500 ft., no date (H. S. Bion). A number 
of specimens. 
The worms showed the first stages in the development of the 
genital organs. Testes and ovaries were present, but the male 
ducts and spermathecae were very incomplete. The diagnosis of 
the genus is suggested by the fact that the dorsal setae are of the 
same type as the ventral.

External Characters.—Length about 23 mm. (the specimen was 
much curled up); diameter 2 mm. Colour dark grey, blotchy

anterior end much lighter, almost white. Segments 106. 
Prostomium ? prolobous, relatively large; first segment very 
short. 
Dotsal pores absent. 
Setae small very closely paired ; aa < bc, dd=} circumference
