187L] DR. J. C. COX ON NEW AUSTRALIAN LAND SHELLS. 53 



to verify his measurements, I wrote to the Curator of the Hull Lite- 

 rary and Philosophical Society, who replies, in a letter dated Jan. 13, 

 1871, "I cannot imagine where Mr. Brown obtained his informa- 

 tion. I have been to the Trinity House, have seen some of the 

 leading men, and have looked over their Museum ; and there is no 

 such thing as the skull of a Narwhal about the place ! They have 

 two large horns, fixed one on each side of a door, with a silver plate, 

 and the name of the donor engraved thereon ; but that is all belong- 

 ing to the Narwhal ; and they are very much surprised at the state- 

 ment I made. I made inquiry of some other people, but could not 

 gain any information. T then went to a friend of the Gravilles ; and 

 he told me he had never heard of the skull with two tusks, which 

 he thought he should have done had there been such a thing. He 

 said he knew the widow had several tusks, which were sold some 

 time ago, as he saw them before they were sold. Captain Graville, 

 the elder, was frozen to death some years ago in the Arctic Seas ; 

 and the said horns were sold some time after his death by his widow. 

 I asked if he thought it possible that the son had any thing of the 

 sort ; and he replied that he had not, as he had lived next door to 

 him for some time, and was very intimate with him, and he was 

 quite certain that if he had possessed such a thing he should have 

 been made acquainted with it." 



There are several interesting questions about the dentition of the 

 young Narwhal, which is said to have molar and incisor teeth ; but 

 it will be necessary to procure fresh specimens before any certain 

 conclusions can be arrived at respecting them.
