38 Reports and Proceedings. 



the so-called eye-peduncles were really the reversed cheek-margins 

 of the same Trilobite, or belonged to another individual, seemed to 

 admit of some doubt. Several interesting illustrations in confirma- 

 tion of the latter of these opinions were exhibited. There seems to 

 be no doubt that the fossil in question has been mutilated, as Mr. 

 Johnson stated that when he first saw it the margins of the sessile 

 eyes of the common Calymene BlumenbacMi were distinctly visible.^ 

 Among the fossils exhibited may be mentioned one which Mr. 

 Beckett considered as a Calamite, from the Dudley Limestone, though 

 the absence of all remains of land-plants in these early measures 

 pointed rather to the specimen exhibited being an Orthoceras. Mr. 

 Hollier exhibited a number of beautiful Trilobites and several Limuli 

 from the Coal-measures. Mr. Ketley also exhibited a specimen of 

 PJiacops Downingice, var. spinosus, only one specimen of which is 

 recorded, and that from the Ludlow rock. — Dudley Herald, Dec. 5,

Montreal Natural History Society. — The usual monthly 

 meeting of this Society was held on Monday evening, Oct. 26tli, 

 1868. The President, Principal Dawson, F.E.S., etc., etc., in the 

 Chair. E. Billings, Esq., F.G-.S., read a paper entitled, '-'Note on 

 the Bones of a Mastodon found near Dunnville, Oct., 1868." 



On reading the announcement in the papers of the discovery of the 

 bones of a Mastodon, near Dunnville, two weeks ago, I left Montreal by 

 the first train for the locality. On arriving there, I found that the 

 accounts were somewhat exaggerated. The remains were not so 

 large as had been reported, and besides were in a very poor state of 

 preservation. The tusks had almost entirely disappeared — there 

 remaining only two or three small fragments, about a foot long and 

 one or two inches thick. No part of the head remained except the 

 posterior portion of the right ramus of the lower jaw. There are 

 seven molar teeth with the enamel, as usual, well preserved. There 

 is a nearly perfect thigh bone and several other bones of the legs 

 and feet, most of them more or less broken and decayed. There are 

 a few of the vertebra, some fragments of the ribs, and a number of 

 other imperfect bones. 



On examining the teeth, I found the remains to be those of the 

 common American species Mastodon OMoticiis or TrilopJiodon OMo- 

 ticus, according to Dr. Falconer's classification. Judging from the 

 size of the teeth and femur, I should say that this animal was a 

 Mastodon of medium size, perhaps nine feet in height. I do not 

 think the tusks could have been fourteen feet long. The longest and 

 most perfect skeleton of this species known is that which was 

 mounted by the late Dr. Warren, of Boston, and which is now, I 

 believe, in one of the museums of that city. It measures seventeen 

 feet in length from the front part of the fece to the insertion of the 

 tail, and is a little over eleven feet in height. The tusks are about 

 eleven feet in length, and it seems probable, therefore, that those of 

 the Dunnville skeleton were not so long.
