362 MR. R. S. BAGNALL'S REPORT OF 



Siphonaptera or Fleas. 

 A very rare species, * Ceratophylhis vagabundus (=insularis 

 Rothschild), in nests of the cormorant and on the bird itself. 

 C. garei Rothsch., was found in puffin burrows and bred from 

 nests of the eider duck, whilst on the mainland Pulex cnniculi 

 Dale was taken from a rabbit burrow. One of the party 

 reported the presence of the domestic species, Pulex irritans. 



Coleoptera (Beetles). 

 Two interesting maritime forms, viz. Aepus maritinms and 

 Micralymma, were found under some of the larger stones on 

 some of the islands; the maritime bristle-tail Machilis maritime/, 

 was seen, and several thrips were taken from the bladder- 

 campion and other plants. 



Centipedes and Woodlice. 

 Seven different centipedes were noted, viz. Lithobuts forficatus 

 L., L. variegatus Leach, L. glabratus C. L. Koch, L. crassipes 

 C. L. Koch, Geophilus proximus C L. Koch, Schendyla 

 nemorensis C. L. Koch, and '* Scolioplanes maritima Leach. 

 The last-named is a maritime form for which I had often 

 searched, but till now without success. 



Of the Woodlice two of our commonest species, Oniscus 

 asellus and Porcellio scaber, were common, but the maritime 

 Ligia oceanic a was not seen. 



Seaton Sluice and St. Mary's Island, 

 Saturday, October, 191 i. 



The last field meeting was arranged for a stretch of the 

 nearer Northumbrian Coast. The party, meeting at Hartley 

 Station, walked down the long lane, past Seaton Delaval Hall 

 and across the bents to the shore, and thence to St. Mary's 

 Island, after visiting the curious old disused harbour at Seaton 

 Sluice. As this is a favourite ramble and was taken so recently 

 as 1907, 1 will not lengthen an already long report in detailing 

 the procedure of the day. 



A report of the 1907 meeting under Dr. Woolacott's guidance 

 will be found in Mr. Alaric Richardson's report for 1907 (see 

 Vol. Ill, pp. 479-480, 1909).
