860 species, is the fullest local marine moUuscan fauna yet 



enumerfited from the tropical South-west Pacific. I was much 



interested to find, during a few hours' search upon the Panie beach, 



situated about 120 miles W.N.W. of the Loyalties, several of the 



species which they mention. These are now first recorded from the 



mainland, some of the more noteworthy finds being : Megerlia 



sanguinea, Chem. ; Ervillia sandwichensis, Smith ; CohhinheUa 



stephensi,^l.& S.; Marginella ellipiica, J^,edfie\d; Ri^soa j^yrrhacme, 



M. ife S. ; Schismope ferriezi, Crosse, and *S'. moreleti, Crosse ; 



Barleia chasteri, M. & S.; Mangelia rhodacme, M. & S.; Caecum 



exile, Folin; Cadidus viviperidens, M. &■ S.; Minolia glaphyrella, 



M. ife S., which I cannot separate from M. pudibunda, Fischer, 



and Pyrgidina gliriella, M. & S., which I have also seen from 



Thursday' Island, Queensland.
