In a fine-grained, brown sandstone from Mount Nathorst, 

 seventeen shells and casts are found belonging to a species 

 of Ästarte closely allied to Astarte elegans. The shells are 

 broad (the best preserved specimen has a breadth of ЗО'"'^ 

 and a length of 29'°'^), they are also thick and are covered 

 by rather coarse, close lines of growth. The Greenland speci- 

 mens do not agree particularly well with the above-quoted 

 figures of this very variable species , seeing that they are 

 both broader and more convex. The specimens resemble much 

 more closely two in the Munich Collection from the Bajocian 

 or Inferior Oolite of the Cotswold Hills, Gloucestershire, but 

 the latter are more drawn out posteriorly and have a narrower 

 lunule. 



Astarte elegans., Sow. is quoted by Fox-Strangways ^) and 

 Woodward^) from the Dogger, Millepore Bed, Grey Limestone 

 and Cornbrash of Yorkshire; also from the Inferior Oolite, 

 Murchisonae-, Humphriesianum- and Parkinsoni-zones, and from 

 the Cornbrash (Macrocephalus-zone) from Dorsetshire to York- 

 shire. 



Schlossere) quotes Astarte elegans as occurring in the 

 «brown Jura Y» or Sowerbyi-zone of Franconia.
