A single specimen was found by Mr. Cuming in sandy mud at 

 the depth of seven fathoms. — W. J. B. 



Typhis coronatus. Typhis testd pyriformi, albidd, subventri- 

 cosd, quinquefariam varicosd, varicibus magnis, rotundatis, in 

 spinam subtilem subincurvam spirant versus desinentibus, trans- 

 versim substriatd, striis subremotis ; canali elongatd: long. 1,

 Hab. ad Colombiam Occidentalem. (Salango.) 

 Mus. Cuming. 



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

 each varix overhangs that part of the spire which is immediately 

 opposite to it. The suture of the spire between each varix is deeply 

 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. 

 Tjtphis Belcheri. Typhis testd subovatd, albidd, ventricosd, 

 transversim substriatd, tubulis recurvis, quinquefariam vanicosdy 

 varicibus laminatis sublaciniatis in Jrondem crispam spiram ver- 

 sus desinentibus ; canali elongatd, subrecurvd, gracili ; long, 1 9 T >

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

 approaches nearly to Typhis frondosus (J. Sowerby), bears. Typhis 

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



Typhis Sowerbii. Typhis testd subovatd, albidd, quadri- vel 

 quinque-fariam varicosd, varicibus laminatis subfrondentibus ; 

 tubulis subrectis; canali brevi, subrecurvd, gracili : long. £, lat. -^

 Hab. in Mari Mediterraneo.

Named after Mr. James Sowerby, who kindly placed at my dis- 

 posal his fine collection of fossil species, and who also furnished 

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

 Sowerbii.—W. J. B. 



Typhis pinnatus. Typhis testd albd,Jusifurmi,trifariampin- 

 natd y transversim striata, striis Jrequentibus, inter stitiis punctatis ; 

 labri limbo crenulato : long, f , lat. -| poll.

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

 canal 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 clay, calcaire grossier, and subapennine beds. — W. J. B. 



Genus Ranella.
