416 ARACHNIDA—ARANEAE CHAP. 
(ii.) The AGELENINAE also contain sixteen genera, but it is a 
much larger group, some of the genera being rich in species. 
They are mostly moderate or large-sized hairy spiders, living in 
temperate or cold climates. There are about fifty species of 
Tegenaria, seven of which have been recorded as British. 
Our commonest Cellar-spider is 7. derhamai, but the very 
large long-legged species found in houses in the southern counties 
of England is 7. parietina (= guyonit = domestica). There are 
not many species of Agel/ena, but one, A. /abyrinthiea, 1s a common 
object in this country, with its large, close-textured web and 
accompanying tube spread on grassy banks by the wayside. 
Coelotes atropos is a formidable-looking spider, found occasionally 
under stones in England and Wales. Another genus, Cryphoeca, 
has three British representatives. 
(iii.) The HAHNIINAE are recognised at once by their spinnerets, 
which are arranged in a single transverse line, the posterior pair 
being on the outside, and generally much the longest.  Hahnia 
contains several species of very small spiders, of which four or 
five are British, usually occurring among moss or herbage. The 
aberrant form Micodamus (Centropelma), usually placed among 
the Theridiidae, is removed by Simon to the Agelenidae, forming 
by itself the sub-family (iv.) NICODAMINAE. 
Fam. 31. Pisauridae——The Pisauridae are hairy, long-legged 
spiders, intermediate, both in structure and in habits, between the 
Agelenidae and the Lycosidae. Many new genera have recently 
been added to the group, but many of them only include one or 
two species. 
Pisaura is spread throughout the temperate regions of the 
Old World, and P. (Ocyale) mirabilis is common in England, 
being found abundantly in woods and on commons. It is a 
striking spider, more than half an inch in length, and its elongate 
abdomen is marked on either side with a sinuous longitudinal 
white band. 
There are some thirty species of Dolomedes scattered over the 
temperate regions of the world. D. fimbriatus is a rare species in 
marshy spots in the south of England, and is one of the largest 
British spiders. The ground-colour is deep brown, with two 
longitudinal yellowish stripes both on cephalothorax and abdomen. 
The genus Dolomedes is replaced by Thaumasia in South 
America.
