siphuncle is placed about half-way between the centre and 

 the venter, and that it is almost cylindrical, but slightly 

 constricted at or near each of the septa. 



Black Island, Swampy Harbour, Lake Winnipeg, J. B. 

 Tyrrell, 1889, two specimens, and D. B. Dowling and 

 L. M. Lambe, 1890, two specimens. 



These are referred to the genus Eurystomites, Schroder, 

 on the authority of Professor Hyatt, to whom one of the 

 most perfect specimens was sent for examination. In a 

 letter recently received, Professor Hyatt says of this 

 specimen : " The suture has a decided broad ventral lobe 

 and lateral lobes, and internally there is an impressed 

 zone shewing a true close coiled nautilian form. The 

 siphuncle is ventrad of the centre, small and with delicate 

 walls." Nautilus Hercules of Billings, from the Hudson 

 Kiver formation of the island of Anticosti, which Hyatt 

 doubtfully refers to the genus Litoceras, has a broad 

 flattened venter and a similar kind of coiling to that of 

 E. plicatus, but both sides of the outer volution of Nauti- 

 lus Hercules are distinctly angular.
