On some supposed new Species of Harthworms. 387 
While this paper has been passing through the press, 
Mr. Mitchell has returned to England, and has re-examined 
the specimens of Deuterophlebia. He was able to recall some 
of the circumstances of their capture, and adds the following 
note on the exact locality where they were found :— 
“These flies were found floating on the edge of Lake 
Gungabal, which there has a rocky shore. Close to the 
outlet-stream the lake is 11,700! above sea-level, and lies 
close under the glaciers of Hurramukh, which rises to nearly 
17,000', say 5000! above the surface of thelake. The stream | 
from the lake*descends the Wangat Valley, and joins the 
Sind River, an affluent of the Jhelum.”

XLVIT.—- A Note on some supposed new Species of Earthworms 
of the Genus Glyphidrilus. By J. Srepuenson, M.B., 
D.Sc., Lecturer in Zoology, University of Edinburgh. 
In a recent number of this Journal (ser. 9, vol. ix. no. 49, 
Jan. 1922, pp. 51-68), Mr. C. R. N. Rao, of the University 
of Mysore, describes four new species of Glyphidrilus. As 
on a former occasion (Rao, Ann. & Mag. Nat. Hist. ser. 9, 
vol. vili. no. 47, Nov. 1921; Stephenson, Ann. & Mag. Nat. 
Hist. ser. 9, vol. ix. no, 49, Jan. 1922), the descriptions 
appeared to me to be mistaken in many points ; besides, one 
of the four species seemed to be identical with Glyphi- 
drilus annandalei, Mich., and another probably so, while the 
two remaining species were obviously immature, and in all 
likelihood also belonged to G. annandalei. I therefore
