The suture-line slightly incised. The external lobe broad, not deep. 

 The external saddle low, divided into two, somewhat unequal parts 

 by a small adventitious lobe. The first lateral lobe narrow, but 

 Fairly deep, bifid or trifid. The first lateral saddle more strongly 

 developed than the ex- 



3'.

ternal saddle both in 

 breadth and length, 

 almost symmetrical. 

 The second lateral lobe 

 narrow with three 

 points. The second 

 lateral saddle low, irre- 

 gularly lobed. Further, 

 2 — 3 faintly developed 

 auxiliary lobes. 



One of the most 

 complete specimens 

 has a diameter of 8v> 

 mm ; the width of the 

 umbilicus is 1*2 mm, height of the last whorl above the edge ol the 

 umbilicus 4*5 mm; its height above the preceding whorl 3 - 3 mm. 

 The thickness could only be measured approximately; it is a little 

 over 1*5 mm. Different fragments show, that other specimens have 

 been not a little larger. 



Distribution. North-East Greenland: in 3 black calcareous 

 concretions found as boulders at Danmarks Havn, two from Vester- 

 dalen, the third from a place not given (many specimens).

 of the whorl: in A 17 mm; in B 3mm; in C 8mm. 



Indeterminable fragments or imprints of Ammonites, belonging 

 in part at least to other species than those mentioned, were found 

 at the following localities. 



"Kloft I" on Store Koldewey Island in the calciferous and mica- 

 ceous sandstone. 



"4. Saenkning" on Store Koldewey Island in the loose-lying, blue- 

 gray, calciferous sandstone. 



Down from "Trsekpasset" on Store Koldewey Island in a gray, 

 calciferous and micaceous nodule of sandstone, found at a height 

 of 50 m above the sea. — At the same locality, but above the plateau 

 in gray cone-in-cone marl. 



River-bed just to the north of Cape Oswald Heer on Hochstetter's 

 Foreland in a light-gray, fine-grained, calcareous and very micaceous 

 sandstone.
