102 Terrestrial Isopoda (Woodlice) of Yorkshire. 
Genus HAPLOPHTHALMUS Schobl. 
HAPLOPHTHALMUS MENGII Zaddach.—This small Woodlouse 
was first recorded for Yorkshire by Mr. R. S. Bagnall, from 
specimens taken at the same time and place as the two former 
species. I have since obtained a number of specimens from 
under deeply embedded limestone boulders on the river side 
at Grassington in May and June, 1914, and under the stones 
of the first weir below Settle Bridge in May, 1914. 
This species appears to frequent the burrows made by 
worms and other creatures found under stones. It is pure 
white with longitudinal ribs on each segment of the thorax. 
Although rare, this species appears to be widely distributed. 
It has been taken in Derbyshire, Cheshire, Lancashire, North- 
umberland, Durham, and eight counties in Ireland. 
HAPLOPHTHALMUS DANICUS Budde-Lund.—The Rev. T. R. 
R. Stebbing added this species to our Yorkshire fauna from 
specimens obtained at Naburn Hall on the occasion of the 
British Association’s visit to York (Victorian County History 
of Yorkshire). Mr. R. S. Bagnall, also found it on the 
cliffs at Whitby on March 2oth, 1913 (Zoologist, April, 1912). I 
have obtained a single specimen in a cold frame in my garden 
in April, 1914, and two specimens in a greenhouse at Lister 
Park, Bradford, November 25th, 1915. 
FAMILY ONISCIDA. 
Genus PLATYARTHRUS Brandt. 
PLATYARTHRUS HOFFMANNSEGGH Brandt.—The Rev. T. R. 
R. Stebbing found this interesting little Woodlouse at Naburn 
Hall (Victory County History, Yorks.). 
Mr. F. Booth and I found it very common in ants’ nests 
under large stones, while looking for Acicula aciculoides, a small 
land snail, on the roadside from Linton Common to Wetherby, 
September, 1908, Mr. F. Booth and Mr. T. Stringer also found 
it in a similar situation at Milnthorpe in April, gro. 
Mr. R. Standen, of Manchester, has some interesting notes 
on this species in the Lancashire Naturalist for November, 
1900. 
Mr. T. Stainforth gives some further interesting notes on 
this species in The Naturalist for December, 1915, in a paper 
on ‘ The Guests of Yorkshire Ants.’
