Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1908 edition. Excerpt: ... (Geology of North America, Pl. VI, fig. 11), it is distinguished by its less globose shell. A similar remark applies to Retzia compressa, Meek (Palaeontology of California, Vol. I, p. lt, Pl. II, fig. 7), which is, however, very closely allied to my Kashmir specimens and specially agrees with them perfectly well in size and number of ribs.

Family: ATHYRID./E, Phillips. Sub-family: ATHYRTNIE, Waagen, Genus: ATHYRIS, M'Coy. (Srrnrosna, d'Orbigny.) The family Athyridce is represented among the brachiopoda, frgm the anth, -3. colithic rocks of Kashmir and Spiti by the genus Athyris only. The sub-genus Spirigerella, Waagen, which is so largely represented in the Salt Range, is entirely absent from my fossil materials from the North-Western Hima. layas. I must lay aspecial stress on this fact because Waagen himself supposed Davidson's and...show more
