COLLIER : EXCURSION TO THE WEST OF: IRELAND. 
locality for them, which is on or near the stone walls that 
surround the little meadows and orchards, we found 
them fairly plentiful, although they always needed looking 
for. They were very restricted in locality, and in some 
seemingly likely places we could not find them at all. 
Their average size was 1 mill. in height and 25 mill. in 
breadth, but a few specimens were 20 mill. by 28 mill. 
‘They varied in colour very considerably, much more than 
in any other locality I have ever visited. Vhe type 
specimens (five bands) were the commonest, and were 
generally very handsome shells, as the bands were very 
dark and mostly of the band formula (123)(45), but occa- 
sionally (12345). Below is a list of the varieties we found 
that are acknowledged in the last-published list of the 
Conchological Society :— | 
Var. roseolabiata Taylor.—Ten specimens. 
Var. albolabiata Von Mart.—Six specimens (12345) 
(123)(45) (12345). 
Var. bimarginata Moq.—'l'wo specimens only. 
Var. rubella Moq.—Common. The three largest specimens 
we got were all of this variety. 
Var. libellula Risso.—Common. 
Var. castanea Mog.—Five specimens. 
Var. hyalozonata Taylor.—Four specimens. This variety 
seems to be very soon weathered, and its light-cream 
coloured epidermis comes off in patches, leaving the shell 
pure white with translucent bands. I have them from 
Bundoran without a scrap of epidermis lett. 
M. sinistrorsum ‘Taylor.—My greatest prize, a very fine 
specimen, fully mature, of the plain yellow colour (“del/uda).. 
I found it low down and far in the wall surrounding a little 
meadow near Gleninagh Castle, Cregg, about three miles 
from Ballyvaughan.
