King- George's Bay ; found living- at one spot only on 

 llie iiortli shore. Tlie rocks here are very large and piled up 

 under high cliffs. 



These niollusks are found in daik crevices of ibe huge 

 rocks, exposed only for a brief space during low-water 

 springs. Damaged and wave-worn specimens, indeed, are 

 common on shore after gales, but not the finely sculptured 

 furnis. Some large pnr[)uroid caj)sulcs were found with the 

 shells on the beach just at the N.W. corner of the West 

 Falklands, and most probably belong to this s[)ecies.

Whaler Bay. 



A large capsule, containing six well-developed embryonic 

 examples of this si)ecies, was dredged as above. Jt 

 measured 50 mm. in diameter, while the young shells are 

 alt. 12 X lat. 5 mm. M. Kuj)ert Vallentiu informs us that he 

 lias al.so dredged similar capsules in Stanley Harbour, but 

 till now they liave always been empty. 



Dr. Hermann Strebel figures (/.c. Taf. x. fig. £2) a similar 

 capsule of V. ancilla containing eight or nine embryos.
