Corbet/: Yorkshire Naturalists 



found by the pond side. The Slugs found were Arion minimiis, 

 one adult ; A. circumscriptus, one very minute ; Agriblimax 

 agrestis, very common and of the typical form without markings ; 

 and Liniax tcevis, very numerous and mostly young-, under damp 

 logs. The land shells found included one Hydlinia cellar ia, 

 a few //. nitidula, several H. crystallina, several H fulva, 

 and several Zua hibrica var. lubricoides, while Helix rotundata 

 and H hispida were common. The total for Cusworth thus 

 amounted to 23 species, of which 4 were slugs, 8 land and 11 

 freshwater shells. 



in addition to this, Mr. H. H. Corbett collected about 

 Conisborough Castle one Helix rotundata, one Hyalinia crystal- 

 Unas two H alliaria, and one Clausilia bidentata var. everetti, 

 the two last-named raising the total bag for the day to 10 land 

 shells and 25 altogether. 



The coleopterists present were Messrs. E. G. Bayford and 

 H. Ostheide, who met with the following species : — 



Pterostichus nigrita F. Bibloporus bicolor Denny. 



Anchomenus angusticollis F. Coccinella 7-punctata L. 



Anchomenus albipes F. Exochomus 4-pustulatus L. 



"Hyphydrus ovatus L. Scaphidium 4-maculatum OX. 



Hydroporus planus L. Scaphisoma agaricinum L. 



Ocypus olens Mull. Elmis seneus Miill. 



Tachyporus hypnorum F. -Geotrupes spiniger Marsh. 

 "Trechus minutus F. var. obtusus Er. Rhinosimus ruficollis L. 



It may be noted that the 4 List of Yorkshire Coleoptera ' is 

 published as far as the Staphylinida?, to which Tachyporus 

 belongs. The species marked are not included in the list as 

 occurring in the S.W. district, although they are fairly common 

 everywhere in it. 



Mr. M. H. Stiles, F.R.M.S., reported that, in Micro- 

 Zoology and Botany, with the exception of a gathering from 

 a small spring on the Cadeby Cliff opposite Conisborough, 

 nothing was done until Cusworth was reached. Here, in con- 

 junction with Mr. H. Moore, F.R.M.S., of Rotherham, the 

 ponds were fished with very fair results, although it was late in 

 the day when the party arrived there and wished that more time 

 had been at their disposal. They were especially gratified to- 

 find in the pond on the south, leading from the 'Bubbling 

 Spring,' traces of Volvox globator, the membranous sacs only 

 being present ; this constitutes a new record. In the same pond 

 Bosmina longirostris was very plentiful. Mr. Moore furnishes 

 the following list of Rotifers, which he found in these ponds : —
