vonian and Carboniferous) ; Liassic and Jurassic rocks, chiefly the 

 plant^bearing beds of the Elburz mountains ; Cretaceous rocks, oc- 

 cupying a great area in S.W. Persia — a pale massive limestone, often 

 abounding in Hippurit'S, being the most conspicuous rock ; of Cre- 

 taceous age also are volcanic rocks, chiefly dolerites and ash beds, which 

 occur in several parts. The Tertiary rocks are divided into the Num- 

 mulitic series, gypsiferous series, and Makran group. Under the head of 

 Quaternary or llecent are included all the surface-accumulations in the 

 plains and valleys and on the hill-slopes, as well as the raised beaches. 

 Lastly, there are volcanic rocks which have been produced in recent 

 geological times. Part II. consists of a detailed account of the rocks 

 seen by the author in his journey, which extended from Gwadar, on 

 the Arabian Sea, to Bam, Karraan, Shiraz, Isfahan, Tehran, and llesht, 

 and included a visit to the Elburz mountains. F. D.

 The rocks hitherto spoken of as the " plant-bearing series " of India 

 are here definitely named the Gondwtina series or system. An exami- 

 nation of the plants in it indicates the following horizons : — 1 . Kach ; 

 2. Kajmahal; 3. Panchet; 4. Damuda ; 5. Talchir. Nos. 1 and 2 are 

 spoken of as Upixsr, and Nos. 3, 4, and 5 as J^ower Gondwana. A com- 

 l)ari8on of the species of Filices, Cycadea), and Coniferaj with those of 

 Europe shows that the Kach rocks are Oolitic, and probably L. Oolitic ;
