ADDITIONAL SHELLS FROM THE COAST OF SOUTHERN BRAZIL. 



BY WM, H. DALL. 



In the Nautilus for August, 1891, (V, p. 43) the writer enumer- 

 ated fifty-five species of marine mollusks from the southern coast of 

 Brazil, mostly collected by Dr. H. v. Ihering, which greatly 

 extended the known range of many familiar species of the eastern 

 coast of the United States. A second list is now presented which 

 considerably enlarges the number of North American and Antillean 

 species known to extend to the region mentioned. Among the land 

 and fresh-water species, Zonites arhoreiis Say was a" surprise, as well 

 as a shell which appears not to differ from Vertigo antivertigo of 

 Europe. 



Columhella lyrata Sby. described from the Bay of Panama had 

 previously been identified by Dunker among species from Santa 

 Cateriua, Brazil, and is now sent from Bahia by Saffbrd. C. teiysi- 

 cliore, which is a common species in Ceylon and has been received 

 from several Indo-Pacific localities, was reported from Barbados 

 by Cuming and now turns up at Bahia. Labiosa lineata Say is a 

 surprise from San Paulo, and so is Lucinopsis tenuis Recluz. Several 

 of the Patagonian forms are shown to extend further north than was 

 supposed. The species now reported were chiefly collected by Dr. 

 V. Ihering at San Paulo (S. P.) on the tropic of Capricorn, Monte- 

 video (S. Lat. 35°), Rio Grande do Sul (R. G. S.) in S. Lat. 32°, 

 30', Santa Caterina (S. C.) in S. Lat. 26°, and Bahia in S. Lat. 13°
