and rare British Sjriders. 259 



Beach, Portland. A few examples of both sexes were adult ; 

 but the majority were immature females. Up to this time 

 the only recorded British example has been a mutilated 

 female found by Mr. W. Farren and sent to me by him from 

 the New Forest, Hampshire. 



Genus Salticus, Simon (Latr. ad part.). 



Salticus formicarius. 



Attus formicarius et A. formico'ides, Walck. Ins. Apt. i. pp. 470, 471. 

 Salticus formicarius, Cambr. Linn. Trans, xxviii. p. 435. 



In addition to the only record of this spider (hitherto) authen- 

 ticated as British (Linn. Trans. I. c), I have pleasure in now 

 recording another example of the adult male found by the late 

 J. C. Dale, Esq., at the Salterns, near Lymington, Hants, in 

 August 1865. This example was shown to me lately by Mr. 

 C. W. Dale, of Glanville's Wooton.
