Besides the above, Dr. W. M. Rankin has recently published 

 "The Crustacea of the Bermuda Islands" (Annals N. York 

 Acad., xii, p. 521, 1900), and Prof. H. L. Clark has published 

 two papers on the Bermuda Echinoderms (op. cit., xi, p. 407, 

 1898, and vol. xii, p. 117, 1899). 



The nine papers first mentioned are preliminary to a much 

 fuller report on the Fauna of the Bermudas, now nearly com- 

 pleted by the writer, which is to be freely illustrated. It is 

 intended to supply a want long felt by numerous students of 

 zoology who annually visit the Bermudas, Bahamas, and other 

 West Indian Islands. The marine fauna of the Bermudas is 

 largely a colony from the West Indies. 



These preliminary papers give, however, a much fuller idea of 

 the character and extent of the Bermudian fauna than any 

 previous works, relating to the same groups. 



Mr. Pilsbry's paper on the terrestrial mollusks is complete, up 

 to date. It includes 41 species. Of the truly terrestrial forms 

 all except 15 species are supposed to have been introduced in 

 comparatively modern times, and several quite recently. Six 

 species : Helicina convexa, Tkysanophora hypolepta, and Poecil- 

 ozonites with four species, are endemic and not known else- 

 where. The latter genus is the most remarkable, and its largest 

 species (P. JVelsoni) is extinct, but it occurs abundantly in the 

 aeolian limestone, sometimes in strata exposed only at low tide, 

 thus showing that it lived on the islands before their partial sub- 

 mergence, and indicating the comparatively great antiquity of 

 the genus. Its nearest allies are now found in the eastern 

 United States. The Rumina decollata is now the most abundant 

 land shell. It was introduced accidentally, about 1876, probably 

 on plants from TenerirTe or the Cape Verde Islands by Governor
