Exhibits. 



Mr. J. C. Melvill exhibited selections from a series of South American Bulimuli 

 and Drymcei, obtained at the sale of the collection of the late Mr. S. I. DaCosta, 

 containing many varieties of D. felix Pfr. , cognatus Pils. , miit-rinus Rve., Jlexuosus 

 Pfr., trigoitostomus ]ones, etc., mostly from Cauca or Bogota, and D. chanchamay- 

 ensis Pfr., from Eastern Peru. Likewise D. expanstis Pfr., in variety. Also, from 

 another source, a very perfect B. {Metorthaliciis) labeo Broderip, intermediate in 

 coloration between the two DaCosta examples. Mr. Melvill also showed two 

 specimens of the wonderfully constructed Trachycystis scolopendra M. & P., from 

 Port Shepstone, Natal, in which the epidermis, fluted, thickened, and bearing the 

 semblance of regular longitudinal ribs, superimpends the periphery, rendering it one 

 of the most remarkable of South African terrestrial shells.
