408 THE CANADIAN NATURALIST. [Vol. viil. 



These are in such a bad state of preservation that it would be a 

 hopeless task to try and identify the species, or to describe it 

 with sufficient accuracy if new. At the commencement of the 

 phragmocone, the largest example does not measure quite three 

 lines in diameter, while several of the specimens would lie loosely 

 in the cavity of a wheaten straw. The surface of the whole is 

 so muoh worn that it is impossible to tell whether there was a 

 median or an apical groove, or none at all. Iltasyouco River. 



26. Belemnites (?) At the same locality as the preceding 



shell, and associated with it, are portions of what seems to be 

 either another species of Belemnites, or at least a different 

 varietal form, and unfortunately, in quite as bad a state of 

 preservation. The guard, though elongated and narrowly cylin- 

 drical in shape, is much thicker and more conical than is that of 

 the fossil last described, and it is not improbable that the present 

 species may prove to be conspecific with a Belemnite fron Dakota, 

 supposed by Meek and Hayden to be a slender variety of their 

 Belemnites densus, and figured on Plate V. (figs. 1 a, 1 b, 1 c,) 

 of the "Palaeontology of the Upper Missouri." Detached phrag- 

 mocones, probably belonging to both species, are not unfrequent 

 also at the Iltasyouco Kiver. These, though not very well pre- 

 served, appear to show that the fossils of which they formed a 

 part are referable to Belemnites proper and not to Belemnitella. 



27. The nature of the curious frag- 

 ment represented in the wood cut is 

 uncertain, but it may have been a por- 

 tion of an Aptychus, a fragment of the 

 pen of a calamary allied to Teudopsis, 

 or a piece of an aviculoid shell. 



28. Serpula (?) — Three casts of the shelly tube of a 



species of Serpula. The most perfect specimen has been secret- 

 ed by the animal on nearly the same plane, and is twice bent, so 

 as to present the appearance of a flexuous-sided triangle with the 

 angles blunted and half of one of the sides wanting. The others 

 are simply flexuous, and no vestige of the test or of its surface 

 markings is preserved on any of them. Locality, Iltasyouco 

 River. 



The fossils above enumerated are of much interest as affording 

 the first instance yet observed of the occurrence of a well marked 

 fauna of Jurassic age in British Columbia. It is true that fossils,
