Typhis coronatus. Typhis testd pyrįformi, albidd, sulventri- 

 cosci, quinquefanmn vnricosd, varicibus magins, rotumiatis, in

The short, sharp, incurved spine which forms the termination of 

 each varix overhangs that part of the spire which is iramediately

 excavated into a succession of little pits or wells, Found by Mr. 

 Cuming in sandy mud at the depth of six fathoms. — W. J. B.

Found by Captain Belcher, R N., whose name this species, vvhich 

 approaches nearly to Typhis Jrondosus (J. Sovverby), bears. Tijphis 

 frondosus is a Grignon fossil. — W. J. B.

 me vvith the most perfect individual which I have seen of Typhis 

 Sowerbii.—\V . J. B.

Obs. The sides of the canal in the specimen are broken, but the 

 canai does not appear to have been entire close to the aperture, 

 though the sides of it approximate there very nearly — W. J. B. 



The fossil analogues of this genus have been hitherto found in the 

 London ciay, calcaire grossier, and subapennine beds. — W. J. B.
