After a careful examination of the material of this species in the Btitish Muséum (Nat. 

 Hist.), London, and the literature I hâve no doubt that Venus discors Dillwyn, V. mttscaria^ 

 V. pulicaris, V. mixta and V. cii,neata (ail of Lamarck), and Circe marmorata Reeve are ail 

 synonyms of Gafraritim dispar (Dillwyn). 



The species is discussed at length by Romer, and his figures of the shells of différent 

 âges show the distinguishing characters of the species very well. 



Distribution : — Gafrarium dispar has a wide range in the Indo-Pacific Région. A detailed 

 list of its records was published by Lynge. 



In the "Siboga" collection it is represented by two young shells collected at the Anchorage 

 off Seba, Savu (St. 58) and Lamakera, Solor Island (St. 61).
