forked septum, C. equestris, fig. 234. The name Cetjcibulum 

 is applied to the "cup and saucer" division; Galeeus to the 

 species with a half-spiral septum, fig. 236 ; Teochita to the 

 trochaeform, spiral species (Infundibum, Montf.) fig. 237; and 

 Crypta to Crepidtjla, Lamarck, with a septum across the shell, 

 fig, 239, PI. xh,

CAMILLUS. Montf. A genus founded upon a minute, spiral, 

 shell, with a triangular aperture, turned over the back of the 

 last whorl. It is figured in Soldani's Testacea Microscopica. 



CAMITIA. Gray, described ? (adopted from his Synop- 

 sis.) A genus founded on a very interesting shell brought by 

 Mr. Cuming from the Isle of Luzon, Philippines. It is round 

 and flat, and in general appearance like a E-oteUa ; but the Co- 

 lumella presents very singular characters, being quite separated 

 from the body whorl by a spiral slit, and from the enter lip by a 

 deep notch under a strong tooth. Behind the Columella is a 

 spiral canal. Ex. C. pulcherrima, PI. xxviii. fig. 590. 



CAM0STEJ5A. Eoissy? Cleidotheeus, Stutchbury. 



CAMPULOTUS. Guettard, 1759. Magiltjs, Montfort, 1810. 

 The former is therefore used by some authors on the ground of 

 priority. 



CANALICULATED. Applied generally to any distinct groove 

 or canal. 



CANAL. A groove which characterizes some spiral univalves, 

 where the inner and outer lips unite at the front part of the 

 aperture. This canal is drawn out in some shells to a conside- 

 rable length, in others it is turned abruptly over the back. The 

 family Canaliferse, Lam. (fig. 372 to 401) are all provided with 

 this canal. 



CANALIEERA. Canaliferes, Lam, A family belonging to the 

 order Trachelipoda, Lam. nearly corresponding with the family 

 Entomostrata in De BlainviUe's system, and described as having 

 a canal of greater or less extent at the anterior part of the aper- 

 ture. This canal is sometimes straight, sometimes tortuous, and 

 in some genera it is recurved over the back of the shell. All the 

 shells have an operculum, and the thickness of the perfectly
