*C. elevata. 



Shell conical or pyramidal, with four nearly equal sides, the 

 plane of the sides more or less rounded, one of the sides nearly 

 flat, the opposite corresponding one more rounded, the other tw o 

 sides respectively, are neither so flat nor 60 rounded : substance o 

 the shell very thin. Plate X. fig. 3. 



This fossil is of a pyramidal form from the aperture upwards; it 

 has annular waved transverse lines in succession from the apex to 

 the mouth; these lines are subimbricate, lying partly on one ano- 

 ther ; at the opening there are four lips, one on each side corres- 

 ponding to the planes, and prolonged downwards ; at each corner 

 of the pyramidal form and at the opening, the transverse lines are 

 drawn up, forming with the lips a sort of festoon around the base. 

 The cavity of this shell is filled with the same substance as the pre- 

 ceding species. The limestone from which these fossils were ta- 

 ken, is of a grey colour and chrystaline texture ; it is not generally 

 known whether it belongs to the Silurian or Carboniferous scries.

 Continents. By John L. Le Conte.

The number of forms of animal life common to the two conti- 

 nents is far from being great ; and it is therefore presumed that any 

 new examples of such extensive distribution will not be without in- 

 terest to the student of nature. Many of the species which are 

 found on either continent, were undoubtedly introduced from one 

 to the other, in the ordinary articles of commerce. Thus, for in- 

 stance, Calandra oryzee has been brought in rice ; Pt.invsftir, An- 

 thrcnus museorum and ■pimpinellm, several species of Dermestes Al- 

 tagenus, and many others belonging to different orders of insects 

 would accompany the various necessaries of life, or the numberless 

 articles of luxury which are continually crossing the ocean. Carabus
