limestone. Its agreement with both Schellwien's figures and Tscherny- 

 scHEw's, which latter, it is true, is classified under the title Sp. cfr. 

 Fritschi ScHELLW. (1902, PI. 13, Fig. 1), and also with specimens 

 from Spitzbergen, make me quite certain as to the determination. 



The relation borne by the species to related forms, especially 

 to Sp. supramosqiiensis Nik. has been dealt with in some detail under 

 that species, but it will probably be found suitable if we pay some 

 further attention to its occurrence in Arctic regions, and to the inter- 

 pretation given by earlier writers to its presence there. Wiman 

 mentions the species both from King's Bay, from which locality he 

 has had 3 specimens for examination, and also from Cape Fanshave 

 (Hinlopen Strait), from which he has seen one specimen, which, 

 however, he considers cannot be specifically determined. 



On inspecting the Spitzbergen collections of the SAvedish Riks- 

 Museum, I found, however, two additional specimens of Sp. Fritschi, 

 having on their label : ^'Spirifer mosquensis" (in the handwriting of 

 the late Professor Lindström), "Cape Fanshave" (in the handwriting 

 of Professor JoH. Gunnar Andeussonj. These specimens from Cape 

 Fanshave have formed the basis of the presumption of the occur- 

 rence of the mosquensis horizon in Spitzbergen of authors previous 

 to HoLTEDAHL. WiMAN mentions something of the historical deve- 

 lopment and assumes a contradiction in the mention made by 

 TscHERNYSCHEW (1902, p. 688) of the specimens determined by Lind- 

 ström and JoH. Gunnar Andersson as Sp. mosquensis, as Tscher- 

 NYSCHEW, when mentioning Sp. Fritschi, says "Exemplare", and 

 only one then was at Wiman's hands. Wiman has not had 

 these specimens for examination, but they confirm in a very high 

 degree, the determination of Sp. Fritschi Schellwien from Spitz- 

 bergen. 



N:o 9. Spirifer fulmari d. sp. 



PI. XXVII, Figs. 17-19. 

 I consider that I ought to classify as a new species a specimen 

 of a Spirifer belonging to the mosquensis group, and obtained from 

 the solid rock, 275 metres above sea-level in the Mallemuktjæld 

 {N:o 166). I do so in consequence of the great difference it shows 

 from the other species belonging to the above-mentioned group, in 

 spite of the material being restricted to an isolated ventral valve 

 which in addition, sufferred some damage during the life of the 

 animal, which healed later on. The name of the new species has 

 been given after the bird — Fulmarus glacialis — from which the 

 Mallemukfjæld has obtained its name.
