STUBBS : LAND AND FRESHWATER SHELLS OF TENBY. 359 



Var. rufula-zonata. — Not uncommon on St. Catherine's Rock, 

 in the Jubilee Gardens, Ritec Cottage-Gardens, and at Giltar. 



Var. ochroleuca. — This is a very distinct and beautiful form. 

 The bands, markings, and lips are orange or salmon-pink. It has 

 varieties corresponding to those of the ordinary type, but all the 

 markings, etc., are orange or salmon-pink instead of the normal 

 colouring ; both forms live together. 



Var. alba.— There are colonies of this variety on the Castle Hill, 

 St. Catherine's Rock, and South Cliff. It is also very abundant in a 

 grass court-yard at Pembroke Castle. 



Var. hyalozona. — With the last in all places. This is really the 

 type form of the last, and, as in var. ochroleuca, it has varieties corre- 

 sponding to those of the ordinary type form, but lips and markings 

 pure white. 



Var. coalita var. nov. — Like the type, but having the bands 

 above and below coalesced, leaving a white zone round the suture 

 and umbilicus only. The Burrows and Jubilee Gardens, not common. 

 H. acuta. — Very abundant, and having nearly the same range as 

 H. pisana in the district. It is most plentiful on the Burrows, in 

 some sheltered spots reaching 20 mm. in length of spire. The best 

 month for collecting this, and indeed the last four species, is September. 



Var. inflata. — Much inflated specimens of the type and vars. 

 bizona, coalita, flammulata, and strigata are not uncommon. The 

 Burrows, Jubilee Gardens, etc. 



Var. elongata. — Giltar, and a bank in the Jubilee Gardens. 

 Not common. 



Var. bizona. — Abundant in some parts of the Burrows, and 

 fairly plentiful in some other places. Specimens from St. Catherine's 

 Rock have very smooth and regular bands. 



Var. coalita. — Common with the last variety. This is var. bizona 

 with the two bands coalesced, forming one broad band. Intermediate 

 forms connecting the two are common. 



Var. flammulata. — Common on some parts of the Burrows 

 living with var. bizona. 



Var. strigata. — Abundant, and very variable as regards the 

 streaking. 



Var. articulata. — This beautiful variety is found on some parts 

 of the Burrows and in the Jubilee Gardens, but it is not very plentiful. 



Var. nigrescens. — Not uncommon in the Jubilee Gardens, and 

 a few other places ; it is usually rather smaller than the other forms 

 with which it associates. 



Var. alba. — A single specimen of the type form from Pembroke 

 Castle ; albino H. itala and H. virgata are found in the same spot.
