M'Clintock' on his travels in search of Sir John Franklin. At 76° 

 and 77° N. Lat. he found on Grinnell Island, Bathurst Island, and 

 Prince Patrick Island fossiliferous limestones belonging to the marine 

 Carboniferous. As localities for fossils may specially be named 

 Hillock Point, Melville Island (76° N. Lat. and 111°45' W. Long.) 

 and Cape Lady Franklin, Bathurst Island (76°40' N. Lat. and 99° 

 W. Long.), 



The location of these islands as well as of the main localities 

 for marine Carboniferous in the arctic regions, mentioned in this 

 paper, is shown in the map p. 598. 



Haughton \ in his investigation of the fossils collected by 

 M'Clintock, has described and figured two species of Carboniferous 

 Brachiopoda; Productus sulcatus Sow., var. borealis Haughton, a form 

 that partly may be identified with Prod, timanicus Stuck., as we 

 shall endeavour to prove below, and Spirifer arcticus Haughton. 



Respecting these fossils and the figures of Haughton's, Tscherny- 

 SCHEW (1902, p. 692) has expressed the opinion that he considers the 

 Spirifer arcticus Haughton to belong to the subgenus Spiriferella and 

 probably to be identical wnth Sp. saranœ Vern.; on the figurings of 

 Prod, sulcatus Sow., var. borealis Haughton he makes the following 

 remark: "— — —, so scheinen sie mir nicht weniger als zwei 

 verschiedenen Species zu entsprechen: Fig. 1 giebt offenbar eine 

 unserem uralischen Pr. uralicus nahe stehenden F'orm wieder, wäh- 

 rend Fig. 7 recht lebhaft an die grossen Representanten von Pr. 

 timanicus Stuck, erinnert". 



Another locality of marine Carboniferous in the archipelago of 

 Arctic North America is represented by Exmouth Island, N. of Grin- 

 nell Island (77°15' N. Lat. and 95°30' W. Long.) where Sir Edward 

 Belcher found marine fossils that were investigated and figured by 

 Salter. The fauna contained 3 species of Brachiopoda, that were 

 determined as: Spirifer Keilhavii v. Buch, Productus Cora d'ORR. and 

 Prod, semireticulatus Mart., var. frigidus Salt. Respecting this fossil 

 fauna and its stratigraphical importance the reader is referred to 

 Tschernyschew (1902, p. 690—692), where, too, a closer interpretation 

 of the fossils is presented. 



The marine Carboniferous of the Arctic North America Tscher- 

 nyschew (1902, p. 695) generally ascribes to the Upper Carboniferous; 

 after having emphasized the palæontologicai correspondence between 

 the Arctic North American deposits with those of the Urals and the
