Distribution. North-East Greenland: in the loose-lying, 

 hrownish sandstone, occurring 50 m above the sea, down from 

 "Traekpasset" on Store Koldewey Island (1 — 2 spec).

PI. XXXVII, fig. 3. 



About one-quarter of a whorl of an Ammonite may perhaps, as 

 new species, be referred to the genus Aulacostephanus. 



The whorl is somewhat deformed by pressure; its sides seem 

 to have been somewhat flattened and its height is a little greater 

 than its breadth. The external side is also somewhat flattened. The 

 whorl thus assumes an oval, slightly square-shaped section. The 

 slope towards the umbilicus is even. The ribs disappear before they 

 reach quite down to the umbilicus; on the edge of the umbilicus 

 and somewhat above this they are very prominent with an indica- 

 tion of a sharp spine or node; at the same time they now bend 

 somewhat forwards, decrease suddenly in size a little below the 

 middle of the flank and course almost in a straight line over the 

 external side. Most of these ribs dichotomize immediately above 

 their strongest part and further, a new rib is inserted almost at the 

 same place, so that for each rib on the umbilical edge there are 

 about 3 ribs on the external side. In the middle of this the ribs 

 become weaker somewhat, and an indication of a furrow is thus 

 formed. Constrictions present. — The suture-line is not quite distinct; 

 it seems to be somewhat strongly dentated and there is a well-marked 

 "Suspensivlobus". 



Height of the whorl 20 mm, its breadth 18 mm. 



Distribution. North-East Greenland: in free-lying sandstone 

 at the bottom of "Kloft II" on Store Koldewey Island (1 spec). 



72. Garnieria pusilla n. sp. 

 PI. XXXVI, figs. 7, 8 and I). 



The shell compressed with slightly arched sides and a fairly 

 narrow umbilicus. The slope towards the umbilicus short and steep. 

 The inner whorls low and smooth with rounded external side. When 

 the shell has reached a diameter of ca. 2*5 mm, a keel begins to 

 appear on the external side, and at the same time the whorl be- 

 comes more and more compressed and increases greatly in height. 

 The keel, which is finely dentated, is bounded later by a distinct 

 spiral depression on each side. A number of fairly weak, falciform 

 ribs now appear also, but no nodes. Further, the shell is here 

 covered with numerous, very fine radial striae, inclined forwards 

 very strongly on the outside; these striae reach right up to the keel. —
