YORKSHIRE NATURALISTS' UNION AT LOWTHORPE. 207 



piscinalis and V. cristata. P/iysa fontinalis and Planorbis contortus 

 were found in the dam at Brace liridge Mill. The slugs met with 

 were Arioii bourguignati, Limax //laximus, and Z. agrestis. The 

 party were scarcely more successful in their search after terrestrial 

 mollusca, probably owing to the time allowed being short. No very 

 great number or variety rewarded their efforts, although probably 

 many of the smaller species could have been met with in the woods had 

 lime allowed ; but the district not having been previously worked, 

 the local guides could render very little assistance in pointing out 

 habitats, etc., a very necessary aid when time is short. The 

 Zonites were represented by the following species, viz.: -Z cellarius, 

 Z. alliarhts, Z. fiihnis, Z. iiitidulus, and Z. crystallinus, and the 

 Helices by the following: — Helix ne»ioralis and var. roseo-labiata, 

 H. aspersa, If. hispida^ H. ru/cscens, and H. cantiana, the latter being 

 abundant. Vitrina pellucida^ Buli/uus obscunis, Carychitwi mifiiniuin, 

 and Cochlicopa lubrica were also found sparingly. 



For the Entomological Section the report was given by its 

 Secretary, Mr. J. H. Rowntree, of Scarborough, who remarked that 

 the season was too little advanced for many insects to be on the 

 wing, and although the sun shone brightly, a cold wind prevailed. 

 The following imagos w^ere recorded : — Pieris brassica^, P. rapes, 

 P. fiapi, Antliocharis cardamines, Vanessa iirticce, V. ca?-dui, 

 Cceno7iy)npha pamphilus, Arctia lubricipeda, and Alelanippc rivata. 

 Many larvce were obtained by beating the hawthorn, the complete 

 list being: — Vanessa iirtiae, Arctia caja, Odonestis potatoria, Rumia 

 cratcegata, Odontopera bidetifata, Hybernia progeiiunaria, Cheimatobia 

 briimata, Melanippe montanata, Dlloba aeriileocepliala, and Miselia 

 oxyacanflue. 



For the Botanical Section reports were given by Mr. Charles P. 

 Hobkirk, F.L.S., of Dewsbury, President, and Mr. Matthew B. 

 Slater, F.L.S., of Malton, Cryptogamic Secretary of the section. 

 Mr. Hobkirk remarked that the botanists had chiefly confined their 

 attention to the woods and rich bottoms on the east side of the 

 Kelk Beck, with occasional incursions where practicable to the west 

 bank, as far north as Brace Bridge. In the swampy ground nearest 

 to Lowthorpe, Iris pseudacorus was found fairly plentiful and in 

 good flower, also Glyceria aquatica, whilst in many parts of the beck 

 Potainogeton lielovpliylliis, P. crispus, and P. densus were plentiful. 

 In the various changing habitats of the journey 112 flowering plants 

 and ferns were observed, amongst the most interesting of which, 

 besides those already mentioned, were Barbarea vulgaris, Hypericum 

 <juadra?igulum, Anthyllis Vulncraria, Onobrychis saliva, Geum 

 rivale, Potentilla Coniaruin, Potcrium Sanguisorba, Hippuris vulgaris,
