Excursion to Herm. 



Having with them a couple of spades they were able to 

 dig up for the benefit of the uninitiated various Annelids, also 

 sea anemones, e.g. Peachia, Sagartia bellis and gemmacea. 

 Sea-urchins :— Spatangus, and Amphidotus ; and razor-fish and 

 other burrowing bivalves, &c, and to show how it was possible 

 from the mounds on the surface to determine what animal was 

 buried below. 



Further north, a gully between the rocks was visited, 

 which would repay a day's attention from an experienced 

 naturalist. 



This beach is considered the best shrimping ground in the 

 bailiwick, a single individual has obtained as many as ten pints 

 to his own net in one tide. The surface has, however, very 

 materially altered in the last few years, pools have disappeared, 

 apparently filled, and new ones formed ; there seems to be a 

 new and rather deep deposit over the whole area. This is 

 probably caused by tipping ballast from barges into the 

 Russel itself, or into waters from which the strong currents 

 bring up the lighter material; even the quarry refuse and 

 ballast heaps so extensive on the coasts of the Vale and St. 

 Sampson's contribute to this new accumulation. 



Meanwhile Mr. Luff had been seeking entomological 

 treasures. The weather was not bright enough to bring out 

 many butterflies. He secured a few specimens, one of Pieris 

 Rapse (small garden White), Lycsena Alexis (Common Blue) 

 was very abundant, and had been out some time, for all those 

 captured were much worn ; of L. Argiolus (Azure Blue) one 

 specimen was taken resting on a bramble ; Pyrarga Egeria 

 (Speckled Wood) was very common, of Ccenonympha Pamphilus 

 (Small Heath) three specimens were captured in fine condi- 

 tion. This species is never found in Guernsey. One much 

 battered specimen of Painted Lady (Vanessa Cardui) was taken. 



Moths did not appear to be numerous; the only perfect 

 insects seen were : Camptogramma Bilineata (Yellow Shell) ; 

 Euchlea Jacobee (Cinnabar) ; both species were abundant*
