COMCHOLOGY.— The Conchological Section will be represented officially 

 by its Secretaries, Mr. F. W. F'ierke and Mr. W. Nelson. 



Mr. William Nelson writes that a few years ago Askern nnd its immediate 

 neighbourhood was a favourite collecting ground of the Yorkshire conchologists, 

 and as a result many local species, varieties and abnormal forms were found, amongst 

 which may be mentioned white varieties of Livinaa percgra^ L. pahistris, Hebx 

 capivata, and ClatLsdia rugosa. A sinistral example of Helix virgata occurred to 

 the late Mr. Lister Peace. Amongst normally formed shells may be mentioned 

 Helix fusca, whilst J^ythinia leacJni abounds in some of the ditches. The flat lands 

 of Askern Common mentioned in the geological paiagraph is a prolific hunting 

 ground, and numerous species may be obtained by carefully examining the mole 

 heaps. In addition to the genera mentioned before, Vivipaius contcctiis (now ex- 

 tinct in the district), Vertigo aniivertigo, CarycJiium Diininumi^ etc., have been 

 found and no doubt others will reward the careful searcher. 



VERTEBRATE ZOOLOGY.— The Vertebrate Section will be officially 

 represented by Mr. J(ihn Gerrnrd, M.B.O.U., its President, and Mr. Riley 

 Fortune, F.Z.S., one of its Secretaries. 



Somewhat detailed particulars of the mammals, birds, reptiles, and fishes, 

 based upon the oljservations of Dr. Lankester, Mr. Neville Wood, and Mr. Mellor, 

 were given in the iS86 circidar, and it will be unnecessary to repeat them here. 



Numerous birds frequent the woods, including the Nightingale (Owston), 

 Hawfinch, Green and Great Spotted Woodpeckers, Reed and Grasshoppc^ 

 Warblers, Wood Wnrbler, etc., while the Crested and Little Grebes arc on record 

 for the district and should be looked for. 



Of fishes, the most plentiful are the Rudd or Red-eye, Roach, Dace, Bream, 

 Perch, and 3-spined and lo-spined Sticklebacks. The Ringed Snake, Lizard, and 

 Blindworm should be looked for on the limestone, and the small mammals deserve 

 investigation.
