between this species and the Einged Plover, numbers of 

 which were seen later, is that the former has not the black 

 ring continued right round the throat ; it is also smaller, and 

 has black legs, while the commoner species has orange. 



On the sea-shore, which here is composed solely of sand, 

 CocJdean'n officinalis and Cukile maritima were found growing 

 plentifully, as well as Salsola kali; this plant used to be 

 collected in considerable quantities, and then burned for the 

 sake of the soda which it contains. On the sand-hills to our 

 left Calystegia Soldanella grew, and the Sea Holly (Knjngium 

 mantimum) grew sparingly. Arundo arenaria was abundant, 

 and also nearer the sea. Flying about the sand-hills and 

 settling on this grass, great numbers of the Silver Y Moth 

 {Pliisia gamma) were noticed, and the Painted Lady Butterfly 

 (^Vanessa cardui) was frequently seen during the day. Further 

 on, the Sea Beet [Beta maritima) flourished, and also Glaux 

 maritima, the flowers of which have no calyx. 



The following are some of the birds that were noticed along 

 this sea-coast: — Black-headed Gull, Lesser Black-backed 

 Gull, Einged Plover, and Common SanderUng, one of which 

 was picked up dead on the sand in a fair condition. We saw 

 a very large flock of Sanderlings seeking for food on the wet 

 sand, and when they took to flight we saw alternately their 

 beautiful pure white necks and breasts, and their backs, 

 which are mottled with black, brown, grey, and dull white. 

 Two Swifts were noticed as being late in migrating. The 

 shore as we proceeded became more and more shingly, and 

 soon was composed only of pebbles. 



Before turning towards Lydd, Ptosa spinosissima was found 

 growing low on the ground. Jadone montana and Armeria 

 mantima grew close together, making the shingle in some 

 places quite bright with their blue and pink blossoms ; and 

 Silene maritima was found. In ditches near Lydd the Common 

 Eeed [Arundo phrogmites) grew plentifully. We spent the 

 night at Lydd, and took an early train the next morning to 

 New Eomney and Littlestone. Almost immediately after 

 leaving the station several Whinchats were seen, and closely 

 observed ; and before reaching the sea the Smooth Sea-heath
