Monst. — Specimens with a twisted spire are occasionally met 

 with, and a not uncommon form of distortion, in places where there is 

 much traffic, is for the last whorl to be much larger in proportion to 

 the others than usual, and turreted. 



Buliminus obscurus. — Not very common except on the North 

 Cliff, where they live, in fair numbers, among heaps of dry sticks and 

 dead leaves. Shells as a rule dwarfed, and rather bleached. 



Pupa cylindracea. — Abundant everywhere. It varies consider- 

 ably in colour and the length of the spire. 

 Var. edentula. — Rare, Castle Hill. 



Var. curta. — Not uncommon with the type on the Castle Hill, 

 St. Catherine's Rock, and in Heywood Lane. 



Var. albina.— A colony on a wall on the North Cliff, and two or 

 three colonies on walls near Manorbier Castle. 



P. muscorum. — This species is not common in the neighbour- 

 hood ; there are scattered colonies on the Castle Hill, and it is also 

 to be found under stones and among moss on the Burrows. 

 Clausilia perversa. — Very abundant and variable as usual. 



Var. gracilior. — North Cliff. 

 Cochlicopa lubrica. — Widely diffused but nowhere very plentiful. 



Var. lubricoides. — St. Catherine's Rock. 

 Csecilioides acicula, — Two dead specimens on the South Cliff, 

 beneath the Esplanade, and one dead specimen at Hoyle's Mouth. 



Succinea elegans. — Abundant in the marshes, and very variable 

 in colour and shape. They may be taken in great numbers off the 

 leaves of the yellow Iris and Reed Mace. In winter I have observed 

 them hibernating under loose stones on the tops of the low walls 

 enclosing the marshes, when they cover the mouth of the shell with 

 an epiphragm. 



Var. minor. — Penally Marsh, not uncommon. 



Var. ochracea. — Roadside near Holloway Quarry, and Pendine 

 Marsh ; not uncommon. 



Var. longiscata. — Sides of ditches in Penally Marsh ; a well- 

 marked variety and scarce. 



Var. virescens. — Gumfreston and Pendine Marshes ; occasion- 

 ally with type. 



Var. albida. — Rare, ditch near Hoyle's Mouth. 

 Carychium minimum. — Common in damp places throughout 

 the district. About fifty specimens were taken from an old tin kettle 

 lying in a trench of water on the Burrows, apparently none the worse 

 for their temporary immersion.
