however, but the cowslip-primrose or hybrid between Primula 

 verts and Primula vulgaris. In this field our entomologists 

 find, besides the Greasy Fritillary, several interesting Lepidoptera, 

 amongst them being the Burnet Noctua (Euclidia glyphicd) and 

 the Mother Shipton [Euclidia mi). The local Tansy Beetle 

 {Adimonia tanaceti) is also found here, and its little blackish 

 larvae may be seen later in the year feeding on the leaves of 

 the DeviTs-bit-Scabions. 



Keeping to the border of Maltby Wood, along the road 

 leading from Little Cawthorpe to Haugham, we entered the 

 somewhat shallow ravine above mentioned. At the extreme 

 corner of the wood is a small long-disused pit, into which we 

 turned, and this with some eagerness, for we had now arrived 

 at one of the known habitats of Clausilia rolphii. Turning over 

 pieces of chalk and logs of wood, we speedily found the mollusc 

 in a living state, but not in great numbers. Besides this species 

 we found C. lamiuata, C. bidentata, Helix hortensis var. lutea 

 00000, H. rotundata, H. aculeata, H. hispida, Hyalinia alliaria, 

 Hy.crystallina, Hy.fulva, Cochlicopa lubrica, Buliminus obscurus, 

 Carychium minimum ; and of slugs, Arion ater (young only), 

 A. hortensis, A. circu?nscriptus, Agriolimax agrestis, and A. 

 IcB-vis. Of beetles we found Chrysomela polita and Barynotus 

 obscurus. The characteristic plant was the Broad-leaved Garlic 

 {Allium ursinuni), which was just beginning to show buds. On 

 leaving this place — as the time at our disposal would not permit 

 us to visit Haugham Pasture — we crossed the fields to the 

 Haugham and Burwell Woods, whose margins were gay with 

 primroses, cowslips, wild hyacinths, and anemones, the last 

 varying in shade from white to crimson. 



In an adjoining field I found a very good neolithic flint flake. 

 We now re-entered the long winding ravine, which is here a 

 considerable valley, running along the border and within the 

 confines of Burwell Wood, and known as Grisel Bottom. This 

 was also one of the places in which we were to look for Clausilia 

 rolphii, and in which, moreover, we had the good fortune to 

 refind it. In this place we also found C. lam inula, C. biden- 

 tata, Helix nemoralis, H. hortensis (a few dead specimens), H. 

 arbustorum, H. rotundata, H. lapicida (one dead specimen — an 

 interesting find as only two examples had previously been found 

 in the Louth district, and these some years ago by Mr. Kew), 

 Hyalinia cellaria, H alliaria, Buliminus obscurus, Carychium 

 minimum, Cyclostoma elegans, Arion ater (young only), A. hor- 

 tensis, A. circumscriptus, A. minimus, and Agriolimax agrestis.
