344 'Ihe Natural History of Spurn. 



pretty forms of this species were found in vars. punctata and 

 internipta, which were not uncommon, and were represented 

 both in their libelhila and rul^ella forms. These vars. are, I 

 believe, restricted in Yorkshire to Spurn, and the river banks 

 at Barlby, also in the East Riding. 



In banding, Mr. Moore secured two shewing var. rujozonata, 

 to which I can add one with the formula reading (12)0(45), 

 which is very unusual. 



Marine Mollusca. — Mr. A. J. Moore gives the following 

 list of those found : — 



Mytiiiis ediilis. 

 Tellina tenuis. 

 Macoma balthica. 

 Cardium edule. 

 Patella vulgaris 

 Trochus cineraria. 

 ■Calliostoma zizyphin iis. 



Littorina rudis (banded var.). 



, , littorea. 

 Buccinum undatum. 

 Purpura lapillus. 

 Lacuna divaricata, very fine. (Ident. 



by Rev. F. H.Woods). 

 Hydrobia ulvcs. 



Arachnida. — Messrs. E. A. Parsons and T. Stainforth 

 report that a strong north-east wind does not produce the best 

 conditions for spider collecting, and that on this account the 

 results of the excursion were somewhat disappointing. Most of 

 the species peculiar to the Spurn area were taken, but, in addi- 

 tion, little of note. Collecting was carried out on the Headland 

 itself, and on a stretch of the Humber shore, south of Kilnsea 

 and Easington. The best discovery was Cornicularia kochii 

 €amb., three females of which were taken on the Humber side 

 of the headland, and six females on the Humber shore, south of 

 Easington. The species was first added to the British fauna 

 last year, on the authority of several male examples taken on 

 the Humber shore at Barton, Lines., and soon after was found 

 at various other points on both the Yorkshire and Lincolnshire 

 shores of the estuary. The most westerly known limit of its 

 distribution, as far as Yorkshire is concerned, is Brough ; its 

 easterly limit, Spurn ; and as it has occurred at intermediate 

 points, we may justly conclude it is to be found all along the 

 Humber shore. Immature examples of Hyctia nivoyi Luc, were 

 taken, and many more were seen. This species seems very 

 generally distributed over the headland, and always occurs 

 at the base of the thick tufts of sand-grasses. It also occurs 

 on a sandy part of the Humber shore, south of Easington. 



The following were found on the headland : —
