The figures will, perhaps, make the matter plainer. A represents 

 the anterior part of the alimentary tube with the central nervous 

 system and B the same organ in section. The meaning of the letters 

 is as follows: a mouth; b dilated anterior portion of the alimentary 

 tube; <: central nervous system; ^eye; e buccal ganglia; /buccal

Bulimus fasciatus Tiuton [ = HelicelIa barbara (L. )] in Lancashire. — I 



have recently become possessed of several letters written by the late Mr. Thos. 

 Glover, and in one of them, written in 1887, which contained a list of species 

 collected by him, I was interested to find a reference to the occurrence in Lan- 

 cashire of Btdimus fasciatus. He quotes as the locality — " On the beach between 

 Rossall and Fleetwood." Several of our members have, since Glover's time, care- 

 fully searched this part of the coast without success. Mr. J. Ray Hardy, however, 

 informs me that in 1892, whilst staying at Rispham along with his nephew Mr. 

 George Hardy, he discovered a large colony of this species in company with H. 

 caperata and H. virgata, on the grassy banks of an old bye-lane, known locally as 

 the " Roman Road," leading from the village of Bispham to the sea-shore. It 

 occurred in abundance from the shore to about a hundred yards up the lane. This 

 isolation of the colony probably accounts for the species being overlooked by other 

 observers, and as its occurrence has not hitherto been noted I am pleased to have 

 the opportunity of placing on record what must be to Lancashire conchologists an 

 interesting observation, inasmuch as it constitutes the sole record of this species for 

 the county. — J. Wilfrid Jackson [Read before the Society, June 13th, 1906).
