OTHER COMMITTEES. 
Yorkshire Arachnida Committee.—Mr. Wm. Falconer writes: 
This, the first year in the career of the most recently con- 
stituted section of the Union—the Arachnidal—has been a 
successful one, and one or more of its members have been 
present at most of the meetings held during the year, with the 
result that much valuable and enduring work has been accom- 
plished. <A gratifying feature also on these occasions has been 
the interest in spiders evinced by non-arachnological members, 
who have, notwithstanding the superior claims of their own 
special branches of study, found time to secure and hand over the 
casual specimens which came under their notice. Full reports 
and lists of the species obtained have appeared during the year 
in ‘“‘ The Naturalist,’ Upper Teesdale, July, pp. 261-4, ; Malham, 
September, pp 334-6; Spurn, September pp. 344-5; Scunthorpe, 
pp. 394-5; Kirby Moorside, November, p. 403. 
Individual enterprise has been even more successful. At 
the close of 1909, 290 species of true spiders had been reported 
for the county, and during the present year this total has been 
increased by the discovery of 5 other species, new to our area,
