198 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY. 
15. Dretomorrna Layarpr, Hartman. 
Hab.—Port Fila and Undine Bay, Efate. 
16. Partuna FRATERNA, Hartman. 
Hab.—Ravenga, Vanua Lava; Lakona, Gana. 
17. PartuLa aURANIANA, Hartman. 
Hab.—Lo and Hin, Torres Is. 
Mr. H. H. Smith, who kindly compared a specimen from each 
locality with Hartman’s type, notes that the Hiu Island form is 
‘‘ indistinguishable from the type,’’ while of the Lo Island shells 
he writes that they are ‘‘ near awraniana, but there is nothing exactly 
like it in the collection.”” I consider this latter to be only a local race. 
18. ParrouLa prramis, Hartman. 
Hab.—Renée River and Terebu, Espiritu Santo. 
One specimen from the former locality was kindly identified by 
Mr. H. H. Smith, who notes ‘‘apparently P. pyramis, Hartman. 
There are two examples in coll. Hartman, one of which is slightly 
abnormal, and neither is in first-rate condition, as they are weathered, 
but the yellow periostracum still shows. P. albescens is close, but has 
flatter whorls.” I strongly suspect that the two will prove to be 
forms of the same species, and that the synonymy will include 
P. eburnea, P. eximia, and P. proxima, all of Hartman, which forms 
may be local races, but not, I think, valid species.
