POPULAR CONCHOLOGY. 



Indian Ocean, Senegal, &c. ; and one species, Actceon (Tor- 

 natella) fasciata, inhabits our own coasts. Mr. Forbes says 

 that when this species is handled, the animal gives out a 

 milky fluid with a purplish tinge, the body being of a 

 milky-white hue. Philippi remarks that the animal greatly 

 resembles that of the Bulla, 



Iteria. Matheron, — Shell ventricose, egg-shaped, or 

 swollen, almost cylindrical, the spire in the young shell 

 not projecting, when older it is perceptible ; the whorls 

 are numerous, the last very large ; the apex blunt ; the 

 aperture longitudinal, narrow; before [or under] spread- 

 ing, thickened outwardly, or lengthened into an indistinct 

 canal; the outer lip plaited inwardly; the inner also 

 plaited. — 1 species, fossil. 



Z (Tornatella) Cabaneti of D'Orbigny is a fossil. 



Act^onella. U Orb, — Shell short, ventricose, or 

 bladder-shaped, smooth; the spire closed in, or free, 

 always very short; the aperture small, longitudinal, en- 

 larged before, behind strongly contracted, where, in every 

 stage, it is furnished with a slight canal ; the outer lip is 

 sharp ; the edge of the inner lip very strongly thickened, 

 and having three large, slightly oblique folds, which extend 

 to the inside. — Fossil. 



These shells are distinguished from Bulla by the folds 

 of the columella, and from Actceon by the absence of 

 transverse stripes. 



Vol V aria. Lam, — Shell cylindrical, with ob- 

 lique punctured stripes; the aperture linear, and 

 scarcely notched beneath ; the outer lip thin ; inner 

 with four plaits at the lower part. — 2 species, 

 fossil. 



Found in the London and Paris formations.
