NEW AND HARE DORSET LAND SHELLS. 101 



Most conchologists seem to agree in thinking that F. Lilljeljorjii 

 and V. Moulinsiana are the same, though I have never myself had 

 an opportunity of comparing them. 



Mr. Standen remarks that the specimens I sent him from Morden 

 differ from those he has seen, resembling rather V. Lilljeborjii. 



I have noticed that the number of denticles in the mouths of my 

 specimens varies from four to five. During August, 1890, 1 found 

 the species in two other localities, though only one specimen at 

 each, the first at Chamberlayne's Bridges, Bere Regis, on a reed in 

 the adjoining water-meadows, the second in the parish of Bloxworth, 

 in a locality very similar to that at Morden, being in fact on the 

 banks of the same stream at a different part. This latter specimen 

 I found in company with F. edentula, of which I took several speci" 

 rnens on the grasses which grow there in the month of May, 1890. 

 I found a few specimens of F. edentula under sticks and pieces of 

 wood in marshy soil at Morden. And in August of the same year, 

 besides those found on reeds, I took three specimens by means of a 

 sweeping net on the leaves of hazel and sallow bushes in Bere 

 wood, parish of Bere Regis. Three other species of Vertigo have 

 been taken in Dorsetshire (1), F. pygmaea ; (2), F. antivertigo ; 

 (3), F. minutissima. Of F. antivertigo I have myself taken a few 

 specimens under logs and sticks in a heath marsh at Bloxworth, 

 during the past year (1890). Mr. E. R. Sykes, of Weymouth, took 

 F. minutissima in some abundance at Portland, in the autumn of 

 1889, and I found a few specimens under stones there in the 

 month of June, 1890. I also took one specimen on the opposite 

 side of Weymouth bay, not far from Osmington Mills. Dr. Gwyn 

 Jeffreys has taken this very local shell at Lulworth, and Mr. J. C. 

 Mansel-Pleydell records it from Hough ton Wood. F. pygmaea 

 appears to be rare at Bloxworth, and in the neighbourhood, 

 since during the past three years I have only found about six 

 specimens, though I have searched carefully. All these were 

 found either at the roots of grass or under stones in fields. 

 At Weymouth, near the two-mile copse (on the Dorchester 

 Road), I found in September, 1890, a small colony of this shell
