DESCRIPTIONS OF SOME OF THE SPIDERS IN THE 

 FOREGOING LIST. 



Zora letifera, Falconer, p. 111. 



Length of the adult male, If lines, very nearly 4 mm. 

 Adult female 2| lines, 4 mm. 



Closely allied to the common Zora maculata, BL, but of a 

 generally paler hue and less distinctly marked. The legs of 

 the 3 females examined were immaculate ; those of the male 

 had the tibiae of the first two pairs black and a very small 

 dark spot or marking at the fore extremity of the tibise of the 

 third and fourth pairs. The structure of the palpi in the 

 male, and of the epigyne in the female, also differ in the two 

 species. Found in Wicken Fen in June by Mr. W. Falconer 

 and Dr. Jackson ; who do not appear to have met there with 

 the usually common Z. maculata, BL 



Agroeca diversa, sp.n. p. 113. Figs. 1-3. 



Adult female, length 2 lines. 



Very similar in general form and appearance to Agroeca 

 gracilipes, BL, which is fairly ' common where the present 

 spider was found. 



The colour of the Cephalothorax is deep brown with very 

 slight traces of any longitudinal central pale yellow-brown 

 stripe, which is plainly marked in A. gracilipes. 



The legs are dull orange yellow. The genuae, tibiae, 

 metatarsi, and tarsi of the first two pairs deep brown 

 approaching black. The metarsi of the third and fourth 

 pairs deep brown, but less dark than those of the anterior 

 pairs ; the tibiae of the third and fourth pairs are obscurely 

 annulated with dull orange and brown. The abdomen is 

 jet black, the ordinary pattern on the upper side obscurely
