PROCEEDINGS OF SCIENTIFIC SOCIETIES. 71 
round, and the scrutineers appointed found on examination that Mr. Charles 
Baron Clarke was duly elected a Councillor. The proposed alteration of 
the Bye-Laws was read for the second time. 
The only zoological contribution read at this meeting was “On the 
Land-Molluscan Genus Durgella, with notes on its Anatomy and description 
of a new Species,” by Lieut.-Col. H. H. Godwin-Austen. Durgella was 
founded by Mr. W. T. Blanford in 1863, and his paper was the first 
attempt to classify the Indian land-shells by the form of the animal and 
structure of the foot, besides being valuable as regards their distribution. 
The genus contained three species, D. levicula, Bens., D. mucosa, Blandf., 
and D. seposita, Bens. The type, D. levicula, is now in the Cambridge 
Museum. From examination of living specimens, and as compared with the 
type, Col. Godwin-Austen is satisfied of the distinctness of the genus, it 
having but a distant relationship with Girasia, Macrochlamys, ke. He 
doubts, however, if the species mucosa ought to be placed in the genus; 
and states that if the species seposita is the same as his bilineata from the 
Dufla Hills, as Mr. G. Nevill asserts, it must also be removed, for the latter 
is a true Macrochlamys. Durgella has a very remarkable odontophore, 
quite unlike any other Indian species of the Zonidide. The author treats 
further of its anatomy, and characterizes the genus afresh, describing 
D. Blanfordi, from Assam, as a new species. 
Two papers were read by Mr. Francis Darwin, viz., “ On the Theory of 
the Growth of Cuttings, illustrated by Observations on the Bramble,” and 
“On the power possessed by leaves of placing themselves at right angles to 
the direction of incident light.” 
January 20, 1881.—The Rey. J. M. Cromsir, F.L.S., in the chair. 
The proposed alterations in the Bye-Laws were again successively read 
and confirmed, excepting Sect. 2, chap. viii., which was not confirmed. 
A Squirrel’s nest from a holly bush was exhibited by Mr. Charles 
Berjeau, and in his remarks thereon he mentioned he could find no specimen 
of this rodent’s arboreal domicile either in the British Museum or other 
London collections. 
No zoological papers were read at this meeting, but several researches 
on orchids, ferns, &c., were communicated by Fellows of the Society— 
J. Muriz. 
ZooLoGicaL Society or Lonpon. 
December 14, 1880.—Prof. Ftower, LL.D., F.R.S., President, in the 
chair. 
The Secretary read a report on the additions that had been made to 
the Society’s Menagerie during the month of November, amongst which 
special attention was called to two Matamata Terrapins, Chelys matamata, 
and a Uniform Water Snake, Fordonia unicolor, obtained by purchase.
