9 8 ON BRITISH ARACHNIDA. 



It gives some reason, I think, to conclude that there may be yet 

 many such additions still to be made by careful collecting, and 

 more eyes and fingers engaged in the pursuit. The spider under 

 consideration is a widely distributed and abundant form in 

 France ; I have received both sexes of it from Guernsey, and the 

 female from Lisbon. The other species mentioned (Tarentula 

 meridiana, Hahn) is a good sized representation of the well- 

 known group of "Wolf- Spiders," of which we see so many 

 running about upon footpaths, and in woods, pastures, and wastes 

 in hot sunshine during spring and summer. It is, when its real 

 colours and markings are seen through spirit of wine (or other 

 fluid), a variegated and often rather gaily marked spider ; but 

 when running about it would be almost white from its covering 

 of short hoary-white hairs, hence one of its synonyms Tarentula 

 nivalis. This spider was found quite recently near Bexhill in 

 Sussex, in a woody waste, by Mr. Frank P. Smith, of Islington. 

 Another addition to our British list arises from the discovery, by 

 Dr. Jackson, that we have two nearly allied species mixed up 

 under one name in our collections Epeira triguttata Fabr.- 

 Cambr. {Epeira agalena, Blackwall). I have come to the 

 conclusion that the additional species must for the present be 

 called Epeira triguttata Jackson-Kulcz-Bosenberg ; but the 

 difficulty in coming to any certain conclusion, owing to the 

 vague, imperfect, and confused records and descriptions of many 

 authors extending back from the present time to the days of 

 Fabricius the latter part of the eighteenth century may be 

 guessed from the few words of detail appended (postea) to the 

 record of the spider in the subjoined list, and the note on 

 Epeira agalena, Blackw. This part of the subject, however, will 

 probably be of interest to the specialist alone. I will only now 

 add to these few general observations that the occurrence 

 mentioned of another exotic spider (Tritcris stenaspis, Sim.) 

 domiciled in a Dublin hothouse so far bears out the expecta- 

 tion held out in my communication in Vol. XXIX., p. 163, as 

 to the continued coming to us of such immigrants in foreign 

 consignments of plants and fruit, &c. Indeed, within these few
