F. P. SMITH OX THE BRITISH SPIDERS OF THE GENUS LYCOSA. 13 



specimens, see Joum. Q. M. C, ser. 2, vol. 9, No. 54, 

 April, 1904, and the references there given. The drawings, 

 except where otherwise stated, are from spiders in my own 

 collection, and have been made, in every case, whilst the specimen 

 was immersed in spirit. 



Family LYCOSTDAE. 



Eyes, eight in number, of a well-developed type. Four small 

 eyes form a transverse row upon the front part of the head, 

 the remaining eyes, much larger in size, forming a quadrilateral 

 figure upon its upper surface.* Male palpus devoid of the 

 processes known as "apophyses" found in the majority of spiders. 

 Spinners normal. Tarsal claws, three. 



The Lycosidae, popularly termed Wolf-spiders, are amongst 

 the best known of our indigenous species, many of them being 

 abundant in almost every ] art of the British Isles. They may 

 be recognised with very little difficulty by the arrangement of 

 the eyes. Lycodia (Zora) of the family Clubionidae and Textrix 

 of the Agelenidae have their eyes arranged on a somewhat 

 similar formula ; the former, however, has but two tarsal claws, 

 and the latter has abnormally long spinners. Pisaura and 

 Dolomedes, of the family Pisauridae, closely approximate the 

 Lycosidae; but the quadrilateral figure formed by the four 

 posterior eyes is so wide behind that the eyes might reasonably 

 be said to form a strongly curved row. In addition to this, they 

 are not so sharply divided into large and small, and, what is far 

 more important, the male palpus is provided with an apophysis.

 spoken of as " arranged in three rows of 4, 2, 2."
