52 Mr. ©. R. Narayan Rao on some 
new examples assigned to the genus Glyphidrilus, mainly 
from Coorg and Shimoga (Mysore). Through the courtesy 
of the Director of the Zoological Survey of India, I was 
enabled to examine in June 1918 the above forms belonging 
to the Indian Museum, and more recently I was given the 
opportunity of recomparing the examples of Glyphidrilus 
with my own material. I am thankful to the Museum 
authorities. 
The two new species, G. rarus and G. saffronensis, of 
which there are a large number of sexually mature forms in 
the collection, are without a trace of clitellum, puberty- 
tubercles, and latero-ventral wing-like expansions or ridges 
of the body-wall. Besides, the seta-distances and the size 
of the sete vary to an extraordinary degree in the four 
species, and I am of opinion that these characters, which 
are associated very largely with growth and sexual maturity, 
cannot be relied upon as a very safe diagnostic feature. In 
a few important particulars the generic characters of Glyphi- 
drilus have to be recast and written thus :— 
Genus Guypuiprinus, Horst. 
1900. Michaelsen, ‘ Oligocheta ” in ‘Das Tierreich,’ p. 459. 
Prostomium pro- or zygo-lobous. The first 12-22 somites 
are circular in cross-section, hard and large; the body 
behind is four-cornered (in preserved specimens). Anus 
dorsal and large, surrounded by a few extremely short 
segments and a variable number of them in front also, are 
marked off from the rest of the body by their shortness. 
Setz on the middle of body are invariably larger ; the seta- 
distance dd = <or>aa. The clitellum, if present, is marked 
by the possession of puberty-tubercles and latero-ventral 
ridges or wing-like expansions of the body-wall. These, 
together with the clitellum, may beabsent. The position of 
male aperture varies, is not easily made out, and is placed as 
a rule within the clitellum. The spermathecal pores, either 
single or groups, occur in front of the male aperture, in the 
intersegmental furrows from two to six somites within the 
seta-space be. A well-developed gizzard in front of septum 8-9 
occupying segment 8 or 74, 8 and 95. Calciferous glands 
absent ; cesophageal pouches in somites 9 and 10 may or 
may not be present. Two pairs of testes and funnels in 
somites 10-1], and usually four pairs of seminal vesicles 
in segments 9-12. A pair of ovaries and ovisacs in 
segment 13.
