Postscript. 



The marine habitat of this genus is distinctly interesting, 

 though we must await further knowledge of its anatomy 

 before concluding that it has not been adopted secondarily, 

 as is the case of Onchidium, the only other marine (or, more 

 strictly, amphibious) Pulmonate. 



MISCELLANEOUS. 



Helix rufescens, Pennant. 

 By A. S. Kennaed and B. B. Woodward. 



Mr, E. a. Smith's note on the identity of Pennant's species with 

 Helidgona (Arianta) arhustorum is, of course, one of great interest 

 to all conch ologists. "When, however, it comes to the question of 

 what name should take the place of Pennant's for this well-known 

 species there is likely to be some difference of opinion. 



Mr. Smith gives preference to montana, on the ground that it 

 had been previously adopted by Studer ; but there is nothing to 

 show that C. Pfeiffer was acquainted with Studer's shell in any way 

 or that the application of the name to the shell he figures (pi. vi. 

 fig. 9) was anything more than guesswork. Moreover, the figure in 

 question rather suggests a large Hygr. hisjnda, Linn. ( = concinna, 

 Jeff.), than the shell we have hitherto known as rufescens. On the 

 other hand, striolata (fig. 8) is our old friend and is the name by 

 which it is currently known on the continent ; so we think this 

 name should be preferred.
