12th.—­Marched on eight miles, after five of which we turned to the right, and the pass became and continued narrow, until we reached our halting place, which is something like what we may suppose to be the remains of a mountain, still a good deal elevated above the bed of river.  The mountains continued the same in the gorge, until we came to limestone cliffs, which afforded a peculiar vegetation, Linaria retephioides, Linaria alia pusilla foliis 5-gonis cordatis, floribus luteis minutis pubescens, specimen lost, one or two Rubiaceae, a Salvia, several very interesting grasses, among which is a Stipa, a Composita, Santanoides, a curious Capparidea, Cassia, etc. etc.

The hills have increased in height, in many places they were extremely picturesque, split and divided in every direction.  The valley running off to south on our entrance into the gorge:  river diminished somewhat in size.  Jheely spots, with very deep water common, surrounded with thick Andropogon, Typha and Scirpus jungle.  Few fish were seen and none taken.  Can the Mahaseer not reach this?  Gonorhynchus continue, but they never take a fly; Ophiocephalus, Sowlee; turtle caught by bearers, Silurus.  No less than twenty-three plants novel to me were gathered on the limestone, which looks as bare as the breccia; all its plants grew in small tufts or singly, and all adhered firmly to the rock.  The only tree which continues is Phulahi or Rairoo; Convolvulus spinosus very common, a very curious Chenopodioid, Reseda with Cruciferous qualities.

13th.—­Proceeded to Gurmab, eight and a half miles.  Country continues the same.  The defile after crossing some rather broad water three feet deep, opened out into a rather large valley, near the south end of which Gurmab is situated, and it is ornamented with a good many Rairoo trees, of indifferent size and appearance.  No change whatever in the vegetation; Salsola prima occurs sparingly.

14th.—­Halted at Gurmab.  The hills close to our encampment are of limestone, which is in many places very angular.  Oolite found by Durand in a low range, standing by itself in the valley, it generally bears a vast quantity of nummulites and madrepores.  A flat discoid organized remain occurs in abundance, and probably belongs to the same group. Ukko, Rairoo, Kureel rare, Convolvulus spinosus, Frankenioides, Stipaceum gramen, Euphorbia, Polygonum rheoides, Salvadora, may be found.  Along the water Andropogonoides 2, Typha, Arundo, Juncus, Scirpus juncinus in abundance.  In the water, a new Naias, and Conferveae.  In a ravine near our camp, I found a Cynoglossum and a curious Periploceous plant, in habit approaching to certain Aphyllous, true Asclepiads.
