sandstones and quartzites of the Infra-Trias, probably also include 

 with them other and older rock material along their northern edge. 



Leaving the further discussion of the Tanols for the present, we 

 will now take for consideration the band of Infra-Trias rocks which 

 follows the line of the ridge north of Teer, — that is to say, the next 

 band of these rocks which appears if we cross the strike at right 

 angles in a north-westerly direction. 



If the map be consulted it will be seen that the band extends

Sections in the band J 



of Infra-Trias, north of in a long narrow outcrop trending S.W. by S. 



and expanding somewhat in its middle part 

 south-east of the word Kootnalee. It then becomes accompanied by 

 another parallel band of the same rocks which afterwards joins up 

 with it north of Neelour. The joint band then, after continuing a short 

 way, comes to an end a little west of Ulolee. To the north-weft 

 again there is another completely isolated patch of the same rocks 

 running from the " B " cf Bandah Loharah, spreading out near Durri, 

 3,567 feet, and thence continuing as a narrow ridge to the 2,943 feet 

 hill, where it finally ends. 



There are some considerable difficulties of interpretation apper- 

 taining to this outcrop area of the Infra-Trias rocks and the associated 

 Tanols. On the north side of the great ridge of limestone in the 

 low country between it and the Jurl N., the Tanols dip away towards 

 the N.N.W. at 40 , lowering somewhat as the river is approached. 

 These rocks consist here of a great series of coarse-grained schistose 

 quartzites of white or faintly purplish colour, — rocks in fact agreeing 

 lithologically in every way with the Tanols as defined in this 

 memoir. At one or two places east of Kukotree there appears 

 between them and the Infra-Trias limestone a thin bed of faintly 

 metamorphosed conglomerate, which in many ways resembles the 

 conglomerate at the base of the Infra-Trias, but which might also 

 pass for one of the conglomerates, or more coarsely clastic beds 

 which occur higher among the Tanols, Wynne in one of his sections 1 

 includes the conglomerate with the latter and divides it and them
