A List of Phalangidea and Chernetidea. 117 
SYSTEMATIC LIST OF SPECIES. 
Order PHALANGIDEA. 
Family PHALANGIID. 
Liobunum rotundum (Latr.). 
This characteristic “Harvestman” is fairly common 
during summer and autumn among rough herbage in most 
well-sheltered localities. In our experience, however, it is 
not nearly so abundant in the district as some other members 
of the family. It seems to be generally distributed in the 
British Isles, and is spread over Europe and North Africa, 
occurring also in the Canaries. ~ 
Neighbourhood of Leven, Fife, Aug. 1893, ad. 9s; Merchiston, Edin- 
burgh, Aug., ad. ? ; among herbage on a busby roadside leading through Biel 
to Stenton, East Lothian, Sept. 1894, numerous ad. gs and 9s; also at 
Presmennan, Tynefield, etc., in same neighbourhood, Aug. and Sept., adults 
of both sexes not uncommon ; underneath stones of a broken-down wall at 
Morton, Noy., several adults; young common among herbage by Braid Burn 
in June; Dreghorn, Ormiston, Longniddry, July, a good many, some ?s ad. 
Liobunum blackwallii, Meade. 
Apparently a local and by no means abundant species. 
As yet we have detected it in but one locality: further 
research, however, will no doubt reveal its presence in a 
number of other spots. Probably of general distribution in 
Britain; and recorded from Denmark, Belgium, France, and 
Germany. 
On the banks of Bilston Burn at Seafield, near Rosslyn, 29th June 1893, 
half a dozen 9s., some ad. 
Phalangium opilio, Linn. 
This typical Phalangid is generally distributed, and often 
abundant among grass and other herbage in fields, commons, 
waste places, etc., and, like the majority of the family, it 
attains the adult state during the summer and early autumn 
months. Not having met with examples in spring or in a 
hibernating state, we conclude that they all die off on the 
approach of winter, and that there is but one brood in the
