hundred and sixty new forms described. More than fifty new group- 

 names, from sections to genera, liave been proposed, and more than 

 five times as many reduced to the rank of synonyms as unnecessary 

 or belated. The number of species known at present between the 

 beginning of the Oligocene and the present fauna is between three 

 and four thousand, probably less than half as many as wall eventually 

 be obtained and discriminated." 



The richness of the tertiary fauna is clearly shown by the lists of 

 species, the bed of the Caloosahatchie River alone containing 639 

 species, of which 48 per cent, are recent and 28 per cent, are peculiar 

 to the bed. From the Chipola beds 333 species are recorded, about 

 one-half being peculiar to it, thirty-five species surviving to the exist- 

 ing fauna. The Oligocene marl of Bowdein, Jamaica, is also very 

 productive, thus far yielding 435 species, of which 12 per cent, ap 

 pear to be identical with recent species. — C. W. J. 



A List of Species of Moi.i.usca fro:\i South Africa, form- 

 ing an appendix to G. B. Sowerby's Marine Shells of South Africa. 

 By Edgar A. Smith (Proc. Mai. Soc, London, v, 354-402, pi. xv). 

 Tliis valuable fauna list enumerates 390 species, including over 300 

 species not in Mr. Sowerby's work. Nine species are descril)ed as 

 new. The region covered includes only the coasts of Cape Colony 

 and Natal. It may be of interest to know that the so-called Fulgm- 

 afrlcaniis Sowb., based on a half-grown shell in poor condition, is a 

 Fusus ; a figure given of the adult shell shows a columellar callus de- 

 tached from the whorl at the lower part, forming an umbilical

This paper contains some very interesting forms, among them two 

 species of the genus Hoinalaxis, a species of Scissurella, one Kleviella, 

 and a Fluxina. All of the species are excellently figured. — C. W. J.
