CETOTOLITES. Fossil Ear-bones of Whales. 



THE Eev. Professor Henslow, in his Paper entitled " On 

 Concretions in the Red-crag at Felixstow, Suffolk,"* in 

 which the attention of geologists was first called to their 

 animal and cetaceous origin, has appended my determina- 

 tions of some of the most remarkable of those bodies, by 

 which not fewer than three, and probably four, species of 

 whales have been added to the Catalogue of British Fossil 

 Mammalia. I have proposed to call the bodies in question 

 "cetotolites,' 1 'f p as they consist of portions of the petro- 

 tympanics, or ear-bones of large Cetacea.
