terminating edges of the trap flows. The latter are of the usual dark, 

 basaltic, and softer amygdaloidal kinds. Their dip undulates at low angles, 

 being generally to the south and south-west, and. their connexion with 

 the remainder of the trap area is interrupted to the south near Naithra, 

 and again in the immediate neighbourhood of Mhurr, by the interven- 

 tion for short distances of other rocks. 



At the southern side of this isolated portion of the trap area is a 

 Intertrappean near narrow recess from which they have been denuded, 

 Lukmeepur. exposing the Jurassic sandstones as highly sili- 



cious craggy hills, projecting above the surrounding trap flows. Near 

 the western edge of this, not far from the village of Lukmeepur, some 

 cherty blocks and shaly fragments of intertrappean beds, containing 

 Tliysa Frinsepii, were found scattered over the surface of a small ploughed 

 field, the soil of which also contained many of these fossils. The band 

 could not be found in situ, but there was no doubt of its occurrence near 

 the spot. These fossils afford an additional proof of the identity 

 between these traps and the accumulations of the Deccan. A little 

 Biilimus or Lymnea and two or three pear-shaped fruit-like bodies, ribbed 

 outside, but without internal structure, were found at the same place, 

 as well as a few woody plant-fragments. A peculiar crystalline trap, 

 with separate felspar and augite crystals, which may be a dyke in the 

 other traps, occurs in a stream close by the locality. 



The northern extension of this portion of the traps in the neigh- 

 Sandstone bed in trap3 hourhood of Malka presents a strong scarp to-

Jurassic rocks. Among the lowest trap flows here a 30-foot bed of 

 soft red and mottled red and white sandstone, with distinct quartz 

 grains, is clearly interstratified and may be traced for a considerable 

 distance.* It is well seen in the left bank of a stream about a mile 



* This sandstone, clearly interstratified wit^ the traps, is an unusual feature in Kutch, 

 hut may find a parallel in those north of the Nerbudda, described in Mr. Blanford's 

 Eeport, Vol. VI, part 3, page 165.
