As Smith and Lynge hâve shown Circe plebia (Hanley) ^), C. erythraea (Jonas), C. artemis 

 (Deshayes), C. metcalfei (Deshayes) and C. paeta Romer ") are ail synonyms of C. sulcata. 

 Hanley's species C. plebia from the Philippines, as I found on examination of the type-shell, is 

 based on a full-grown shell ; at this stage the shell appears more quadrate, with the postero-dorsal 

 border more straight, posterior margin more truncate and the ventral margin more arcuate. 



The shells of C. sulcata^ as w^as noticed by Lynge, exhibit a great variety of colour markings. 



Distribution : — Circe sulcata has been recorded from the Red Sea, the Persian Gulf, 

 Mergui Archipelago, Gulf of Siam, Java, the Philippines and Viti Island. 



In the "Siboga" collection there are shells of this species from the Bay of Pidjot, Lombok 

 (St. 33), the Anchorage north of Ubian (St. 99), and the Anchorage east of Dangar Besar, 

 Saleh Bay (St. 313). 



i) Lynge wrongly spells this species as Cytherea plebja. 



2) In Smith's work the spécifie name of the species is wrongly spelt as paeta.
