96 THE NAUTILUS. 



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

 names, from sections to genera, have 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 will 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 Bowden, 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 OK SPECIES OF MOLLUSCA FROM SOUTH AFKICA, 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). 

 This valuable fauna list enumerates 390 species, including over 300 

 species not in Mr. Sowerby's work. Nine species are described 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 Fulgur 

 africanus 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 

 rimation C. W. J. 



DESCRIPTIONS OF SIXTY-EIGHT NEW GASTROPODA FROM THE 

 PERSIAN GULF, GULF OF OMAN, AND NORTH ARABIA SEA. By 

 JAS. COSMO MKLVILL and ROBT. STANDEN. (Ann. and Mag. of 

 Nat. Hist., Ser. 7, vol. xii, pp. 289-324, pi. xx-xxiii.) 



This paper contains some very interesting forms, among them two 

 species of the genus Homalaxis, a species of Scissurel/a, one Kleinella, 

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