DONOVAN I A CANDID! SSI MA. 389 



represented by a unique specimen in the Museum at Penzance, which is 

 unfortunately not now accessible, owing to the war. I hope I may be able to 

 figure it in some future volume of this memoir. I should be glad to do so in 

 memory of the late Mr. J. Cornish, after whom Mr. Bell named this interesting 

 fossil ; it was owing to a chance conversation between Mr. Cornish and myself in 

 1883 that Wood's attention was first called to the importance of the St. Erth 

 deposits. Mr. Bell has now ascertained there is another specimen in the British 

 Museum (Natural History).

 rather strong longitudinal costse, intersected and granulated by transverse ridges ;
