136 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA. [noew. pol. exp. 



With regard in the first place to the Bajocian, we cannot of course 

 think of any comparison with the geographically adjacent Jura districts of 

 Russia; for in the whole of east and north central Russia the series of marine 

 Jura deposits only begins with the Callovian. 



It is uncertain whether deposits of the age of the Bajocian occur only at 

 Cape Flora, or also in other arctic regions. Toula^ describes from Kuhn 

 Island in East Greenland a Jurassic fauna, rich in Lamellibranchs, which he 

 designated "Middle Dogger". The occurrence in this Dogger fauna of a Be- 

 lemnite resembling Belemnites fusiformis Quenst., is interesting; and we 

 have already seen that our Belemnites sp. (cf. Beyrichi 0pp.) from the Bajo- 

 cian of Cape Flora was allied to Bel. fusiformis Quenst. = Wurttembergicus 

 0pp. It is extremely doubtful whether we ought to conclude from the occur- 

 rence of such a Belemnite, that a close affinity exists between the fauna of 

 the Bajocian at Gape Flora, and the Dogger of Kuhn Island, from whence 

 Toula, moreover, mentions Goniomya Vscripta Sow. i. e. a species already 

 occurring in the Lower Bajocian. The circumstance worthy of notice is that 

 both in the Dogger of Kuhn Island, and in the Bajocian of Cape Flora — 

 that is in high arctic regions — the group of hastate Belemnites occurs, which, 

 according to Neumayr, is wanting in the boreal and Russian Jura^. 



There is only one more region within the polar circle, where Jura depos- 

 its older than the Callovian, certainly occur, Wilkie Point, Prince Patrick's 

 Island, from which Haughton^ described a few fossils as Lias. Neumayr^ 

 declared them to "belong probably to the middle region of the Lower Oolite." 

 In this faunula, an Aviculid form, "Monotis" septentrionalis Haught. occurs, 

 which however shows no similarity to our Pseudomonotis Jacksoni n. sp. 

 from the Bajocian of Cape Flora.
