110 THE NAUTILUS. 



Lea, Barnes, turned from bis writings bewildered and con- 

 temptuous. 



Enthusiastic lover of Nature, indefatigable explorer of wild 

 and sparcely peopled regions, in advance of his time in taxo- 

 nomic instinct, Rafinesque missed being a zoological genius by 

 his obscurity of expression, his careless haste and his incurable 

 confusion of ideas. 



This seems a heartless estimate of a life devoted to science ; 

 but for the time being, I speak impersonally, and merely of his 

 relation to molluscan nomenclature. His high spirit under 

 crushing misfortune, that is beyond praise. 



MELANIDIA Raf., Analyse de la Nature, 1815, p. 144. Sub- 

 stitute for Melania Lamarck, therefore taking the same type, M. 

 amarula (L. ).' 



PHYSINA Raf., loc. cit., substitute for Physa Drap. , type Physa 

 fontinalis ( L. ) . 



LAPHROSTOMA Raf., loc. cit., substitute for Neritina Lam., 

 type N. meleagris Lam. 



VIVIPARELLA Raf., loc. cit. , substitute for " Vivipara Lam.," 

 type Helix vivipara lAiin. = Viviparus vivipara (L. ). 



PLEUROCERA Raf., Amer. Monthly Mag. etc., Ill, 1819, p. 

 355. No species described in the original publication. Subse- 

 quentl} r Rafinesque described Pleurocera verucosa (Annals of 

 Nature, 1820, p. 11) which has been selected as type by Han- 

 nibal (Proc. Malac. Soc. Lond., X, 1912, p. 169). This is 

 Angitrema verrucosa of Tryon. 



ELLIPSTOMA Rafinesque, American Monthly Magazine, etc., 

 IV, p. 42, 1818 ; Journ. de Physique, etc., Bruxelles, vol. 88, 

 p. 424, 1819. Type E. gibbosa Raf., selected by Hannibal, 

 1912; Proc. Malac. Soc. Lond., X, p. 168. The prior name 

 Ellipsostoma de Blainville was not a generic but a family name, 

 hence does not affect the status of Ellipstoma. 



The description of this genus recalls Angitrema of Tryon' s 

 monograph (Strepomabidae) . Mr. Hannibal has identified E. 

 gibbosa Raf. with Angitrema geniculata (Hald.), a species not 



1 Types of this and the following three names fixed according to Art. 30, 

 sect. II f of the International Code.
