which Dr. Stoliczka has ascertained to be of Middle Cretaceous age*. 

 But they do not belong to the Cretaceous series, being overlapped 

 by the Ootatoor group, so that they peep out only at one or two 

 places at its base. Near Madras they are more widely deve- 

 loped, and Messrs. King and Eoote have found beds with marine 

 fossils intercalated with them, of which they give the following 

 generic listf : — 



Fish-scales (unclet.). 



Ammonites, two or three species. 



Belemnites ? 



PateUa? 



Phynchonella? 



Cy therea ? 



Cypricardia ? 



Tellina? 



Anatina (Thracia?). 



Leda, two or three species. 



Lucina ? 



Cultellus? 



Ostrea. 



Inoceramus. 



Lima. 



Pecteu. 



Unfortunately these are ill preserved, and as yet no conclusion as 

 to their age has been deduced from them. 



YI. In Cutch, however, a region long since brought to notice in 

 the ' Transactions ' of the Society $ by Captain Grant, the evidence 

 of the age of the plant-beds containing Palceozamice &c. is much 

 more clear. This interesting country has lately been surveyed and 

 described in an elaborate report by Mr. Wynne § ; and a very large 

 collection of fossils has been brought together, on the description of 

 which Dr. Waagen is engaged. Mr. Wynne divides the Jurassic 

 series of Cutch into two groups, upper and loiver (using these terms 

 with a local signification only, and without reference to the Upper 

 and Lower Jurassic divisions of European geology). The lower 

 group is richj in marine fossils ; and plant-remains are rare or 

 absent. In an abstract account of the results of his examination 

 of the Ammonites of this fauna ||, Dr. Waagen states that he distin- 

 guishes eighty species ; and on the evidence afforded by them he 

 provisionally correlates the several beds of Mr. Wynne's lower, 

 group % with European formations ranging from the Bath Oolite to 

 the Etage Tithonien and Upper Kimmeridgian. It is the upper 

 group of Mr. Wynne's division that contains the greater part of the 

 plant-beds. The demarcation of the two groups is not very definite. 

 Mr. Wynne states** that between the beds which contain distinct 

 and well-preserved plants, and the highest marine fossiliferous beds 

 of the lower group, intervenes a considerable thickness of beds with 

 ill-preserved plants, and "the indefinite boundary between the 

 lower and upper groups may be drawn anywhere through them." 

 There is, however, "a broadly marked difference between the 

 general character of the lower and upper groups of the forma- 

 tion." The latter is probably freshwater or estuarine. Only in 

 the western part of Cutch are marine fossils found in the upper 

 group, "some of which, according to Dr. Stoliczka, possess peculiar 

 interest from their relations to South-African forms "ff. The whole
