Two NEW CYPR.KIDA;. By MRS. AGNES F. KKNYON. Proc. 

 Mill. Soc. of London, vi, 68, Aug., 1900. Cyprcea kanilaui is a new 

 species from the Hawaiian Islands. The description and figure 

 seem very close to a large siz< j d (28 mill.) G. helvola L.; specimens 

 of this species from Hawaii differ considerably from those of the 

 Indo-Pacific region. Trivia acutisulcata is described without habitat. 



DESCRIPTION OF Two SPECIES OF CTPR^EA, BOTH OF THE SUB- 



UENUS TRIVIA. By JAMES COSMO MELVILI Annals and Maga- 



xiiKi of Nat. Hist., Aug., 1900, p. 207. Both species were received 

 from Mr. Fred L. Button. C. (Trivia) yalapayensis from Albe- 

 marle Isl., Galapagos, is a new peculiar form having a " shining 

 enameled callosity over the whole centre of the dorsal region, com- 

 pletely obliterating the sulcus if any exists." C- (Trivia) Buttoni is 

 a small globular straw-colored species with few, continuous ribs. Its 

 habitat is unknown.
