70/10/26." Not only are these two clearly distinct, but T. paivw 

 so closely agrees with other specimens determined as T. recurvus 

 Koch, that I consider that the name given by Crosse should be re- 

 garded as a synonym of T. recurvus. Probably when Prof. Hutton* 

 wrote that Trophon paivre belonged to his new genus Kalydon, he 

 intended to refer to T. hartley i.

No writer subsequent to Lamarck has identified this Australian 

 species. In the Geneva Museum are three specimens, apparently 

 cotypes of Buccinum vinosum. A note beneath the tablet, perhaps 

 by Kiener or Chenu, remarks that these specimens do not conform 

 to Lamarck's phrase, "labro intus striate" 



By the kind help of Mr. W. L. May I sent a series of Tasmanian 

 B. adelaidensis, exhibiting range of variation, to Geneva. From 

 these my correspondent picked out a form representing P. littori- 

 noides Ten. -Woods with the assurance that this perfectly corres- 

 ponded to the Lamarckian types of B. vinosum. Other varieties of 

 this species are represented by Bicinula adelaidensis Crosse & 

 Fischer, Cominella albolirata T. -Woods and Purpura propinqua 

 T. -Woods. Examples of the latter, which I gathered at Huskis- 

 son, Jervis Bay, mark the eastern limit of the species. 



Rapa incurva Dunker.

In the British Museum are two shells from "Raines islet, N.E.C. 

 Australia, J. B. Jukes," and two "N. Australia, Mrs. Ince," in the
