GRAVESEND. 4O9 



Massa. Mosses. _ On the hardest chalk hills, it is 

 true, some fine Hypnum sometimes appeared ; but we 

 nevertheless remarked that this district around Gravesend 

 was not especially favourable for mosses. There was no 

 sign of these seen, though I looked carefully for them, 

 either on the arable fields or inclosures which were sown 

 with Clover, Sain Foin, &c, not even once on the reins 

 by the hedges. 



The Woodlouse. Oniscus cauda obtusa integerrima. 

 Linn. Fauna Svecica, 1256, occurs in multitudes every- 

 where on the chalk, that it has as it were taken up its 

 quarters in these places [T. II. p. 53. J When anyone 

 came near it, it drew itself together, so that it lay per-

 Linn. Faun. Svec. 814 [Anthrocera Filipendulae, Burnet 

 moth']. This beautiful moth, Piaril, which made quite a

 up its abode in old Chalk pits overgrown with small 

 bushes, where it flew in multitudes ; but outside them it 

 was very rare. It flew very slowly, and not so fast as 

 the other butterflies, Fiarilar. It sat very much on the 

 flowers of Scabiosa pratensis hirsuta C. B. 



Aranea abdomine fusco ovato, linea exalbida pinnata, 

 cauda bifurca, Linn. Faun. Svec, 1223 [A. labyrinthica] 

 occurs here in multitudes, on the chalk hills as well as in 

 other places. I saw it also in Essex. The accurate 

 description which Linnaeus gave in his Fauna Svecica 

 {loc. cit.) of the manner in which it makes its house, bo, 

 relieves me from the necessity of repeating this, because
