cles in each transverse row, on the lower half of one of the early volu- 

 tions, and apparently below the siphuncle. In the large specimen 

 figured, which was recently collected by Dr. Newcombe, and is believed 

 to be referable to this species, the ribs are small, rounded and closely dis- 

 posed. The tubercles are badly preserved and obscurely indicated, but 

 they appear to have been both large and distant. In each transverse 

 row thei'e are indications of four tubercles, three below the siphuncle and 

 one above. 



Skidegate Inlet, at Bearskin Bay, (the fine specimen figured, which is 

 upwards of eight inches in length, and more than four inches in its maxi- 

 mum breadth,^— and two fragments) ; and at Maple Island, a specimen 

 consisting of one nearly complete volution. North side of Cumshewa 

 Inlet, two fragments. All of these specimens were collected in Septem- 

 ber, 1895, by Dr. Newcombe, who has kindly presented the one figured 

 to the Museum of the Survey. 



As now understood, this species would seem to be a true Turrilites, 

 rather than a Spiroceras or Helicoceras, although its volutions are far 

 from being closely contiguous. 



Turrilites. (Species uncertain.) 



A worn specimen, consisting of rather more than two volutions, col- 

 lected at Skidegate Inlet, by Dr. Newcombe, in 1897, though too badly 

 preserved to admit of accurate identification or description, is yet clearly 

 distinct from T. Carlottenss. It differs therefrom very obviously in its 

 closely and compactly coiled volutions, imperforate axis, and very coarse 

 transverse ribs. The specimen is now in the Museum of the Survey. 



DiPTYCHOCERAS. 



A specimen of nearly the whole of the outer limb of a species of 

 Diptychoceras, that seems to differ from the D. kpvis of Gabb in being 

 marked by low, rounded, transverse and straight annulations, was col- 

 lected at Cumshewa Inlet by Dr. Newcombe in 1895. The specimen is 

 a little more than two inches and a half in length, nearly circular in sec- 

 tion and about twelve millimetres, or not quite half an inch, in its dorso- 

 ventral diameter, at or near the anterior end. Its sutural line is very 

 similar to that of D. Icevis.
