BRITISH SPIDERS AND THEIR DISTRIBUTION 

7

Early records are often doubtful, due to the recognition at a later 

date that two species have been confused in one (

e.g. Ero furcata 

prior 

to 1912, 

Aranea triguttata 

prior to 1909, 

Episinus truncatus 

prior to 

1906, etc.). All records of 

Porrhommae 

are doubtful up to the time of 

A. R. Jackson's survey of the genus in 1912. Records of 

Tibellus 

oblongus 

prior to 1911 may refer to 

T

.

 oblongus 

or 

T

.

 parallelus

.

Records of 

T

.

 oblongus 

between 1911 and 1938 refer to 

T

.

 parallelus

,

and of 

T

.

 maritimus 

to 

T

.

 oblongus

.

Records of 

Clubiona holosericea 

de G. up to the present time refer to 

C

.

 phragmitis 

and not to C. 

holosericea 

Linn. Records of 

Linyphia montana 

Clerck up to the 

present time refer to 

L

.

 resupina domestica 

de G., whilst 

L

.

triangularis 

Clerck becomes 

L

.

 montana 

Linn. 

Faulty identifications there must be and authors' subsequent 

corrections are easily overlooked. Amongst English records those of 

Tegenaria pagana 

and 

Theridion pulchellum 

refer to 

Tegenaria 

domestica 

and 

Theridion vittatum 

respectively. The true 

T

.

 pulchellum 

has lately been discovered in Berkshire (teste A. R. Jackson). Irish 

records of 

Lophocarenum stramineum 

refer to 

T

.

 nemorale

.

Up to 

1924 Scots records of 

Oedothorax fuscus 

and 

Oe

.

 retusus 

were 

interchanged. 

Our list of species from the British Isles (excluding sub species) 

now comprises 556, excluding the Channel Islands where 7 additional 

species are known (see p. 10). The totals of the four countries are: 

England 534, Wales 318, Scotland 327, Ireland (including Northern 

Ireland) 318. Of the English counties, Rutland (24) and Monmouth 

(29) are least known, followed by Leicester, Bedford, Hunts. and 

Northants, all with fewer than 100 species. Dorset, thanks to O. P. 

Cambridge's intensive collecting, leads comfortably with 396 species, 

followed by Yorkshire, Staffs., Northumberland, Sussex and Hants., 

which all exceed 300. In Wales, Carmarthen is least known with 37 

species; in Ireland, Longford and Tyrone with less than a dozen 

apiece. Wigtown is the only county in the British
