Smethurst exhibited Erebia hlan- 

 divM, from Upper Wharfedale, and 

 Sydrcecia petasitis, from Stanley — 

 both taken by him this season. — 

 Mr. Walter H. Hay showed a spe- 

 cimen of Sirex gigas, taken by him, 

 flying down Briggate ; Mr. John 

 Grassham showed local specimens of 

 Gonepteryx rhamni, bred examples 

 of Ennomos fuscantaria, and a very- 

 good variety of Crocallis elingimria, 

 which he had recently taken on a 

 lamp-post near Adel. — Mr. Samuel 

 Schofield showed a number of in- 

 sects taken at Barwick-in-Elmet ; 

 also several plants, including Actcea 

 spicata, Parlington Wood ; Chelido- 

 nium majus, Aberford ; Parnassia 

 palustris, near Parhngton Park ; 

 Pulycaria dysenterica, and Vihiir- 

 num Opidus. — Mr. Edwin Birchall, 

 F.L.S., exhibited a number of 

 lepidoptera collected by himseK at 

 Rannoch this season, including 

 Zygcena exulans, var. vanadis, Ere- 

 bia cassiope, E. Blandina, and 

 numerous others. 



188th Meeting, Sept. 8th, the 

 president in the chair. Mr. Benj. 

 Holgate read a paper on ''The Com- 

 bustion of Bituminous Coal," which 

 he illustrated by means of numerous 

 examples of coals and cokes, and 

 diagrams of various makes of fur- 

 naces. The discussion was joined 

 in by the president, Mr. S. Schole- 

 field, Mr. Edward Thompson, Mr. 

 James Malt (secretary of the Leeds 

 Geological Association), Mr. James 

 W. Westmoreland, A.R.S.M., and 

 the lecturer. 



189th Meeting, Sept. 15th, the 

 president in the chair. Mr. Wm. 

 Nelson exhibited a number of 



specimens of the various forms 

 assumed by the varieties of 

 Limnma peregra. — Mr. John W. 

 Taylor showed some species of 

 Cylindrella, which is almost entirely 

 confined to the West Indies, and is 

 remarkable for nearly all the species 

 losing the top whorls, and thus 

 becoming decollated. As the ani- 

 mals attain maturity, they desert 

 the upper whorls, which thereupon 

 almost invariably break off. 0. 

 rosea, from Jamaica, lives on the 

 ground amongst dead leaves ; G. 

 lateralis, from Cuba, is remarkable 

 for the detached tube into which 

 the last whorl is prolonged, and is 

 found attached to the face of walls 

 and rocks. G. elongaia difiers from 

 the others in its pure white colour, 

 reversed volution, and viviparous 

 character, and feeds on the lichens 

 clothing the rocks on which they 

 dwell ; while G. Maugeri is remark- 

 able for its smooth polished surface, 

 and hves on the trunks of trees in 

 Jamaica. — Mr. E. E. Prince showed 

 various specimens, including the 

 cast skins of the lizards which had 

 been taken at Riccall Common on 

 the 2nd August. Mr. S. Scholefield 

 showed various plants collected 

 within the West Riding district. — 

 Mr. James Abbott exhibited a 

 plant new to the county — Potentilla 

 Norvegica,"^ yfhich grows abundantly 

 on the banks of the Leeds and 

 Liverpool Canal, between Armley 

 and Kirkstall, and is apparently 

 naturalised. It was first noticed 

 about 1860, by Mr. Wm. Kirkby, 

 of Leeds, and at that time neither 

 he nor Mr. Abbott was able to 

 make it out. In 1868 it was found, 

 apparently native, in Burwell Fen, 



'* This Plant was found in 1873; on the banks of the same Canal, close to Huddersfield.
