31. Vermiculus turritella, Rousseau. 

 Vei-metus turritella, Rouss., Chenu, 111. t. 4. f. 3. 



Vermetus turritella, Rouss., Chenu, Man. p. 319. f. 2298 (copy). 

 This shell is perhaps most allied to V. lumbricalis, var. /3 ; it ia 

 very likely not full-grown. 



32. Vermiculus rouyanus, D'Orb., 1842. 

 Vermetus rouyanus, D'Orb. Ter. Cretac. 2. pi. 233. f. 5-7. 

 V. rouyanus, D'Orb., Chenu, Man. p. 319. f. 2296.

Vermetus albensis, D'Orb. Ter. Cret. 2. p. 386. pi. 233. f. 8-9. 



Hab. Couches aptiennes des environs d'Evry (Aube) (Dupin). 



The descriptions of the last two species do not seem to correspond 

 with the quoted figures ; but whether the names on the plate or the 

 diagnoses are displaced I cannot decide. It is doubtful if these two 

 species are not TurritelltE, as neither of them is known in a distorted 

 state. 



34. Vermiculus carinatus, Homes. 



Vermetus carinatus. Homes, Geol. Reichsanst. 3. p. 486.t.46.f. 17.

Sect. B. Animal tentaculis longis subulatis ; pallio simplici. 



Operculum magnum planum. Testa anfractibus atnpliatis. 



Professor Oersted's drawing of V. eburneus differs from the de- 

 scription of Stimpsonin the long subulate tentacula, and in not show- 

 ing any filaments at the brim of the mantle.
