vex than the other, and the marorin a little flattened. The- 

 foliaceous appendages are large, broad at the base and re- 

 curved towards their points: they are so numerous as to 

 touch or even cross one another, and are probably placed 

 in two rows. The aperture is oblique with rounded edges, 

 ovate, biangular, the angles being at the extremities of the 

 longest diameter, which is terminated by the foliaceous ex- 

 pansions. The lines of growth are numerous, arched and 

 sharp, indicative of an internal animal. The smaller part 

 of the tube is usually separated by a septum as the animal 

 advances. 



I have seen three specimens of this extraordinary shell, 

 two of which, found in the limestone of Kendal, were only 

 portions of the last whorl, which measured 9 inches by 6; 

 the termination of one of these is shown at fig. 2. The 

 third specimen is the same as that figured by Prof. Phil- 

 lips ; it is from near "Whittle in Yorkshire. 1 am indebted 

 to Mr. Gilbertson of Preston for the use of all these spe- 

 cimens: the last has been transferred by that gentleman, 

 along with his splendid collection of mountain-limestone 

 fossils, to the British Museum.
