The specimens named Avicula flabellum by Mr. Sowerby are 
considered by Dr. Jameson to belong rather to the common Ceylon 
species. A. flabellum appears to be synonymous with 4. radiata, 
Leach, a West Indian form.

Hab.—Knysna Harbour, south coast of Cape Colony (J. F. Davis) ; 
Port Elizabeth (Sowerby). 
This species is quite distinct from P. pernula (Chemnitz ?), with 
which Mr. Sowerby has united it.'. It differs in form, colour, and 
sculpture. The P. pernula (Reeve, Conch. Icon., fig. 22) is a well- 
known Mediterranean shell, and occurs also at Madeira, the Canary 
Islands, and on the West African coast. It is of a reddish colour 
with paler scales, and appears to be devoid of the numerous squamulee 
on the ventral side of the valves which are present in P. squamulifera. 
Mr. Davis found his specimens, a fine series of which he has kindly 
sent to the Museum, within the harbour, which is landlocked, the 
entrance from the sea being narrow and between high cliffs. The 
largest specimen is nine inches in length,
