F. M. CAMPBELL — SPIDERS OF HODDESDOIT. 265 



The residence of the Rev. 0. P. Cambrulgc in Dorsetshire has 

 naturally led to more being known of the spider fauna of that 

 county * than of any other, and it is interesting to note a few 

 species which are not yet recorded as being found there, but which 

 are generally distributed or common with us. We have other 

 spiders not yet seen in Dorsetshire, but they arc rare or exceedingly 

 local, and a fortunate capture niay at any time show their presence 

 in that county. They are, therefore, of not so much interest in the 

 comparison of the two faunas. 



The two following species are generally distributed or common 

 about Hoddesdon, and are not recorded as being found in Dorset- 

 shire : — 



Tegenaria Guijonii, Gucr. This is abundant in the whole London 

 district, and is locally known as the Hertfordshire spider. It is 

 one of our largest English species, and attracts attention when it 

 frequents houses, as it does often, and especially during the pairing 

 season, which begins late in the summer. | I have never found it 

 "at home" except in the constructions by man. Its close ally, 

 T. atrica, C. L. Koch, -which in "Weymouth is abundant, J must be 

 here very scarce, for I have only met with one specimen. It is 

 nevertheless common on the south-east side of London. 



Neriene agrestis, Blackw., local, but always to be found in May, 

 June, or July. 



Only one specimen of each of the two following species has been 

 found in Dorsetshire :§ — 



Theridion pictum, Hahn, which is one of our commonest spiders 

 on holly-bushes and pailings. 



jllarpesm muscosa, Clk., abundant on these premises, and generally 

 distributed. I have found two males in cocoons under the bark of 

 an old fence late in October. 



I am not aware of any spider except Epeira scolopetaria, Clk., 

 which is fairly common in the Lea valley, but which is very 

 rarely met with in Dorsetshire. || 



The above comparison is interesting, for these species do not 

 require a very exceptional habitat. 



The incompleteness of my list, both as to numbers and the 

 limited district which is represented, renders it premature to name 

 the spiders which are common to Dorsetshire and which are not 

 found here. Their absence is in many cases accounted for by the 

 nature of the soil. It may at least be said that this locality con- 

 tains many spiders which are still considered rare, and has pro- 



* In the ' Spiders of Dorsetshire ' are recorded 373 species in Dorsetshire, and 

 518 in Great Britain.
