Terrestrial Isopoda (Woodlice) of Yorkshire. 123 
especially in the yards amongst the refuse. It also occurs 
in many cellars of old houses about Bradford and district. 
Like M. pruinosus it frequents most of the greenhouses in the 
district, but it is by no means uncommon in the open.

FAMILY ARMADILLIDIID. 
Genus ARMADILLIDIUM Brandt. 
ARMADILLIDIUM VULGARE Latreille.—Although this species 
is considered common, I do not find it so. Up to the present 
time we have not a single record for it in the district for which 
the Bradford Natural History Society is responsible. This 
comprises the drainage areas cf the Yorkshire portions of the 
rivers Lune and Ribble, the Aire from its source to the Leeds 
city boundary, and the Wharfe from its source to the Wash- 
bourn. It is not uncommon in Nidderdale and on the coast.

October, 1908; Scarberough, May, 1909, F. Booth; Cliffs 
from, Bempton to Bridlington, August, 1909. 
ARMADILLIDIUM NASATUM Budde-Lund.—This species is 
generally found in greenhouses in the North of England, most 
probably it is an endemic species as it occurs in the open and 
away from habitations in the south. 
Greenhouses, Lister Park, Bradford, frequently since 
October, 1908. . 
ARMADILLIDIUM PICTUM Brandt.—It is of great interest to 
be able to include this species in our Yorkshire list, as it has 
only been recently added to the British fauna. It was first 
taken in April, 1913, at Arnside, by Mr. G. S. Spence (anc. 
Nat., July, 1913), Mr. R. Sanderson found it under a log in 
Ling Ghyll, Ribblehead, November Ist, 1915. 
Armadilidium pulchellum Brandt.—-This pretty little crea- 
ture is very like the preceding species, and often occurs in 
company with it ; up to the present I have not found or heard 
of it in Yorkshire, although I have collected it in Westmorland, 
Lancashire and Derbyshire, it appears to favour a limestone 
district.

The Lancashive and Cheshive Naturalist for January has a useful 
“Guide to Current Literature,’ in which the headings of articles of the 
principal journals likely to interest its readers, are given. Dr. A. R. 
Jackson writes on ‘Some Arthropods Observed in 1915’; Mr. F. J. Stubbs 
writes on ‘ The National Neglect of Peat,’ and there are other shorter notes.
