Land and Freshwater Mollusca. — Mr. T. Patch writes : — 

 Twenty-one species of terrestrial mollusca have been recorded for the Point. Of 

 these Helix Jienoralis is probably the most abundant, in all varieties of banding. 

 An investigation by Mr. Denison Roebuck and others, several years ago, showed 

 that the majority had interrupted bands, a fact which was attributed to the dryness 

 of the situation, but recent observations have thrown some doubt on the constancy 

 of this feature ; (12345) is a common form. H. caperaia and H. aspena are com- 

 mon, H. virgata abounds, and its variety nigrescens may be found on ragwort. 

 Minor varieties oi H. nemoralis and H. aspersa have been taken. Old baskets, etc., 

 should be carefully examined, especially if lying on moss or short herbage near the 

 entrance to the warren ; under such have been found Arion nmiimus. Helix pul- 

 chella, H. pys,niaa, Hyalinia alliaria, Hy. crysiallina, Hy. fulva, Pupa cylindracea, 

 P. muscorum. Vertigo edeniula, V. minuiissifna. A former record of Helix itala 

 is believed to be an error ; confirmation is desired. 



Paludesirina ventro^a occurs in brackish ditches and ponds near Kilnsea. 



The following marine species have been taken alive •.—Paludesirina siagnalis 

 (on the clays in millions), Craspedochilus ciiiereus, Limapontia depreisa (pools near 

 the beacon), Dendronotus frondosus (among Tubularia), Patella vulgata (the Den), 

 Helcioii pelliicidti/n, Mytilus edulis, Scrobicularia plana, Tellina tenuis, Maco7na 

 balthica var. carnana, Cardium edule, Mya aretiaria, Barnea Candida (in clay, 

 Kilnsea skerries), Gibbula cineraria, Littoriita liitorea, L. rudis, Buccinum undatum. 

 Purpura lapillus. 



ENTOMOLOGY. — Tlie Entomological Section will be officially represented. 



Lepidoptera. — Mr. G. T. Porritt writes :^Spurn is a very good entomological 

 locality, as a reference to the " List of Yorkshire Lepidoptera " will show. The 

 date of the excursion is, however, a little too early for many of its characteristic 

 species, but among those which ought to be obtained are Charocampa porcelhts, 

 Oigyia fascelina, Leucania littoralis, Mamestra albicolon, Agrotis corticea, and 

 A. lipce, which are all common there. Other species which are mostly abundant 

 la,ter, and which might possibly at the date of the excursion be found, or raked up 

 as larva: or pupte, include Tapinostola elymi, Agrotis 7jalligera, A. cnrsoria, 

 A. tritici, A. aqiiihna, A. ravida, and A. prcecox. Special search should be made 

 at night with a light for the rare Eupithecia innotata on Artemisia, which, 

 although not yet recorded for Yorkshire, is almost certain to occur at Spurn. It 

 was at Spurn, too, that Mr. W. Eagle Clarke took our only county specimen of 

 HeliotJiis pettigera, and also where the rare Eupithecia extensaria occurred. 



Coleoptera. — The Yorkshire Coleoptera Committee will be officially repre- 

 sented. 



Mr. E. G. Bayford writes : — The Spurn peninsula is a paradise for the 

 Coleopterist. Nebria livida F., ALgialia arenaria F., Nacerdes 7)ielanura Schm., 

 Cleonus sulcirost^is Z., uncommon species representing widely differing families 

 have been met with there. Some species, e.g., Anot?iala Frischii F., and Sermyla 

 halensis L. are extremely common. The unicolorous metallic green form of the 

 first named should be looked for. Mr. M. L. Thompson adds Amara bifrons, 

 Calathus fusctis, Trechus obtiisus, Berosus . luridtts, Saprinus 7naritimus, Phyllo- 

 pertha horticola, Cis fuscatus, and many others.
