Shell oval, broader posteriorly than anteriorly, elevated 
and rounded on upper margin, slightly sinuated on under 
edge, of a light-brown colour, with a tinge of green. The 
valves are smooth and shining in the centre, and beset all 
round with short hairs. This is the smallest of all the 
species I have yet met with, and approaches very near to 
Monoc . ovum of Jurine, except that he says his species is 
perfectly smooth, whereas this is beset all round the shell 
with fine hairs. 
Hab . — Yetholm ; neighbourhood of London, &c., 
summer months. — -

Cypbis Joanna, Baird, Trans. Berw. Nat. Club, i, 99, t. 3, f. 8, 1 835, 
and ii, 152 ; Mag. Zool. and Bot., i, 136, t. 5, f. 12. 
— M. Bdwards , Hist. Nat. Crust., iii, 403. 
Shell rounded ovate, narrower anteriorly than pos- 
teriorly, of a brown colour, with an orange mark across 
the back of shell and the lower margin. Shell beset all 
round with rigid hairs, and covered with minute black 
points or dots. Approaches the C. pilosa of Muller, but 
is smaller, and is otherwise distinguished from it by the 
orange mark across the back, and by not being glabrous, 
but marked all over with black, roughish -looking points. 
It is a little longer than C. minuta. 
Hab. — Pool of water on one of the Lammermuir hills, 
near Abbey St. Bathans, Berwickshire, August 1885.
