Euophrys aquipes, Cambr. Paisley (M. Y.). 



E. frontalis, Walck. Aberdeen (J. W. H. T.) ; Old 

 Cambus (J. H.). 



Attus, Walck. = Salticus, Bl., ad partem. 



Attus falcatus, Clerck = Salticus coronatus, Bl. Dunkeld 

 (J. W. H. T.) ; Berwickshire (J. H.). 



A. erratictis, Walck. = Salticus distinctus, Bl. Paisley 

 (M. Y.). 



Salticus, Latr. = Salticus, BL, ad partem. 



Salticus formicarius, Walck. Scotland (Dr. Leach, 

 Encyclop. Brilt. Suppl. to 4th, 5th, and 6th Ed., Art. 

 Aunulosa). Dr. Leach gives no locality nor description. I 

 am inclined to think, however, that his record is Iruslworthy. 



PS. — Since the above list was drawn up, Dr. L. Koch, of 

 Nuremberg, has informed me of two species received by him 

 from Arran, and not hitherto recorded as British, — Pirata 

 Knorri, Scop., and Tarentula actileata, Clk. These, now 

 inserted in their place, supra, raise the total of known 

 Scotch spiders to '215.

70. Spatliegaster baccarnm, L. (= S. interruptor, H.). — 

 This, the commonest of the berry galls, which, shortly after 

 the appearance of the leaves of Quercus sessilijlora, Q.pedun- 

 culata, and Q. pubescens, occurs on their under side, as well 

 as on the catkins, in May, is very sappy, green (catkin speci- 

 mens more or less red), translucent, spherical, hairless, and 

 as big as a pea ; it is so conlexturale with the leaf that a 

 more or less convex, sharply defined, circular disk, with a 

 small boss in the middle, is apparent on its upper surface. 

 This disk has a dian)eter of 3'5 — 6 millimetres ; it is only in 

 a rare case, when the gall occiu's on tlie midrib, that it does 

 not grow through the leaf, and in the catkins it occurs on the 

 flower-stalk. In section the gall exhibits a very sappy, soft 

 parenchyma, which is hollowed out in the centre as a larva
