88 SUB-HIMALAYAN ROCKS OF N. W. INDIA. [CHAP. III. 



Salt-range far to the north-west. Yet we will see that the peculiar 

 deposits of Subathu once ranged far beyond the comparatively small area 

 with which we have been engaged. This area terminates abruptly some 

 miles to the west of the Jumna, but about sixty miles off just east of the 

 Ganges a remnant again appears. It differs in no respect from what we 

 have seen at Subathu, — pale, greenish brown, and red clays, with concre- 

 tionary layers of earthy fossiliferous limestone. The locality is just 

 opposite Biki-Kase, in a depression a short way to the south of Merhal 

 summit, on the ridge which runs nearly parallel to the Ganges for 

 about half the width of the dun. The depression is caused by the more 

 easy denudation of the nummulitic band, which is about half a mile wide. 

 I have already noticed the position of this outlier as being approxi- 

 mately in the continuation of the east end of the main area west of the 

 Jumna, and irrespective of the deep re-entering boundary of the newer 

 deposits in the valley of Dehra. The nummulitic beds here, as elsewhere, 

 exhibit the same features of disturbance as the underlying strata, all being 

 greatly contorted. The Blini group occurs about the base of Merhal, and 

 the other rocks of the ridge show affinities to the Krol and Infra-Krol 

 groups. I cannot say how far this band may continue to the east : this 

 is the only locality in which rocks of this age have been observed by me 

 within the districts of Kumaon and Ghurwal. I have heard of but one 

 other case of their occurrence, and this perhaps requires confirmation. 

 In one of their progress reports to the Government of India (Jour. 

 As. Soc, Ben., Vol. XXV., p. 118), the M.M. Schlagintweit announce the 

 discovery " in the clay-slates in the neighbourhood of Naini Tal, of 

 numerous foraminifera evidently identical with those which accompany 

 the Eocene nummulitic formation." Accepting the statement, it has 

 occurred to me that they may have hit upon some small outlying band 

 of the Subathu beds ; it is sometimes very difficult indeed to distinguish 

 these small bands from the rocks in which they are folded (see, for 

 instance, the road section from Bil to the top of the Sairi hills). That
