as the deficiency of the descriptions, I think they should be excluded 

 from this or any genus.

Genus TEBENNOPHORUS Binney. 



The first accurate description of this genus was pub- 

 lished by Binney in 1841, (Proc. Boston Soc. p. 51). I 

 have therefore given preference to the name he proposed 

 over that of Rafinesque usually adopted. (Vol. 11. p. 19). 



Since the publication of the " Terrestrial Mollusks," the 

 name Tebennophorus has been retained in this country by 

 Stimpson (Shells of N. E.) and by Grateloup, abroad. 

 On the other hand, Philomycus has been adopted in 

 Adams's Genera of Recent Mollusca, where the charac- 

 teristics of the mantle are correctly given ; and in the 

 British Museum Catalogue of Pulmonata.

In ]842 (Boston J. N. H. iv. 2) Dr. Binney referred the 

 Limax Carolinensis of Bosc to this genus. His descrip- 

 tion was the first correct one ever published. I have 

 therefore retained the name he proposed for it. 



Rafinesque's Genus Philomycus bears an earlier date 

 than Tebennophorus. His description appears to me in- 

 sufficient to warrant this species being referred to his 

 genus, as it has been in the works referred to in the 

 synonymy. 



From letters of Dr. Newcomb to Dr. Binney (1845) it 

 appears probable that Limax marmoratus of DeKay's ear-
