The Distribution of Spiders in the East Riding. 285; 
itself on the sand on every part of the coast from Sewerby 
to Kilnsea being the pretty Tvochosa picta. Scotopheus 
blackwallii, Leptyphantes cristatus, Metopobactrus prominulus,. 
Troxochrus scabriculus, Baryphyma pratensis, Xysticus kochi1,. 
Tarentula andrenivora and Lycosa herbigrada, are recorded 
for the Holderness area only as far as the East Riding is con- 
cerned, but all, or most of these species will almost certainly 
be found in other areas when more collecting is carried on. 
(3) HuMBER SHORE AND TIDAL AFFLUENTS.—This division 
includes the shores of the Humber where the conditions are 
estuarine, that is excluding the dune area of Spurn, Easington 
and Welwick, which has its own peculiarities. The banks of 
the tidal affluents such as the River Hull, R. Ouse, R. Derwent,. 
and various creeks partake of the same features. The spiders 
characterising this area are Cicurina cinerea, Halorates reprobus, 
Erigone longipalpis, Erigone spinosa (at Saltend Common 
only), Cnephalocotes curtus, Cornicularia kochiv (recently 
found also on the shores of Hornsea Mere), Lycosa purbeckensts,. 
var. minor together with the Harvestmen, Liobunum blackwalli 
and Oligolophus hansenit. 
(4) SpuRN, EAsINGTON, WeELWick.—The sand-dune area 
of the extreme south-east of the East Riding is one of the most 
interesting we have, and many of the spiders found there are 
not recorded elsewhere in the whole county of Yorkshire. 
The following are the more remarkable species found in this 
area :—Prosthesima latreillii, P. electa, Clubtona subtilis, 
Protadia subnigra, Evrigone atra, var. lantosquensts, E. arctica 
var. maritima, Entelecara trifrons, Heliophanus flavipes, 
Hyctia nivoyi, Euophrys @quipes, and the Pseudoscorpion, 
Chelifer latreillii. If dame Rumour speaks correctly, Spurn 
as the naturalist knows it, is likely no longer to exist. 
(5) HornseEA MERE.—As the only survival of the meres of 
Holderness, Hornsea Mere is worthy of special attention and 
investigation. With the exception of Linyphia impigra, and 
Tmeticus affinis, the type of which was found there, there are 
no species peculiar to the Mere. Naturally many of the forms 
found there also occur in other marshy places in Holderness, 
e.g., Bathyphantes approximatus,  Phaulothrix  huthwantia, 
CEdothorax gibbosus, CE. tuberosus and Enidia bituberculata.. 
Cornicularia kochii, a species which was thought to occur 
only on the Humber shore, was found at Hornsea Mere on 
several occasions last year. 
(6) THe Wo.tps.—The Wold area forms the backbone of 
V.C. 6r. It stretches from Flamborough Head past Driffield. 
and Beverley to Hessle and Brough. As will be seen at a 
glance down column 6 in the following list, the spider fauna is 
a fairly rich one although few species can be put down as:
