June 1908. | BOTANICAL SOCIETY OF EDINBURGH. 347 
MEETING OF THE SOCIETY, 
June 11, 1908. 
J. RurHerrorp Hitt, Esq., President, in the Chair. 
Dr. R. STEWART MacDOouGALL showed specimens of 7'esta- 
cella haliotidew, a carnivorous slug from Buckinghamshire. 
The slugs of the genus Testacella can be recognised by 
their having a rudimentary external shell at the tail end of 
the foot. 7. haliotidea, Drap., measures when full grown 
from 3} to 4 inches. It lays its eggs singly in the soil. Its 
food consists of earthworms, millipedes, and other slugs and 
snails. This species, as well as the other two British 
species of 7'estacella, is a night feeder. 
Dr. MacDouGatu also showed leaf and bud of vine 
damaged by Gryllus domesticus, the house cricket. 
This insect—a dweller near and in the habitations of 
man—feeds chiefly on sweet stuffs and on moist vegetable 
matter. 
The present case of harm done in a vinery was, as far as 
he knew, unusual. The crickets were watched and located by 
lamplight (they hide in the day and come out at night), and 
the plants (leaf and bud) found next morning with the 
damage shown in the specimen exhibited. 
Mr. JAMES FRASER showed specimens of Zgilops ventricosu, 
Tausch, and .#. macrocheta, Shuttl. and Huet, found as 
casuals in the neighbourhood of Edinburgh and not previously 
recorded for Britain. 
Dr. A. W. Bortuwick showed plants of Pseudotsuga 
Douglasii attacked by the Pine Weevil (Hylobius abietis). 
Mr. R. L. Harrow showed a series of plants in flower 
from the Royal Botanic Garden.
