THE GEOLOGIST. 
3. " Supplemental Notes on the Plant-beds of Central Asia." By the 
Eer. S. Hislop. In a Letter to the Assistant- Secretary. Mr. Hislop, in 
notieins: the discovery of more remains of plants, insects, and fishes at 
Kota o-ii the Prauhita, stated that he certainly now thought that the ich- 
thyolitic beds of Kota (probably Lower Jurassic in age) are higher in rela- 
tive position than the plant-sandstone of Nag^Dur, which, with the Sironcha 
sandstone underlying the Kota limestone, behmg to the Damuda group. 
He remarked also that, in his opinion, the TcFuiojjteris of Kampti would 
prove that the Damuda and Eajmahal groups cannot be widely separated. 
NOTES AND QUEEIES. 
Mammalian Eemains. — Fractured bones of Bos primigenius have been 
found on the road between Kelvedon and Coggesham, Essex, by TV. H. 
Thelwall, Esq., who has submitted them to me for identification. — Yours 
faithfully, Charles Caetee Blake. 
EossiL Cocoo>'S OF Leeches. — Dr. Gergens, of Mayence, has lately 
suggested that the so-called fossil eggs of snakes, found in some of the 
freshwater deposits of Germany, may be fossil cocoons of leeches (N. Jahrb. 
1861, p. 670). Under these circumstances it maybe worth while for those 
who possess specimens of the egg-like bodies found in the freshwater strata 
of the Isle of Wight (and which have been thought to be either coprolitic 
or the eggs of Bulimus, or of freshwater tortoises), to re-examine them, 
and compare them with the sponge-like oval cocoon of the common leech. 
Mr. F. E. Edwards figures several of these oviform bodies in his Mono- 
graph on the Eocene Gasteropods, published by the Palseontographical 
Society. — Hirudo. 
Hampshire Basix. — Sie, — Would you kindlj'- solve the following ques- 
tions for me, to which I have not been able to find any satisfactory answers 
in the text-books which are commonly available ? 
1 . What was the extent of the Hampshire Basin ; and when did the up- 
heaval of the present range of chalk hills to the north and west take 
place ; and did the sea, which covered the present New Forest district, 
ever wash against these latter ? 
2. When did the severance of the line of chalk between Ballard Head, 
in Dorsetshire, and St. Christopher's Cliff*, in the Isle of Wight, take 
place ? 
3. Could the following animals be said to be coexistent at any period of 
the Middle Eocene formation (and what?), — DicJiodon cuspidatus, Hyceno- 
don, 'Paloplotherium annectens, and Spalacodon ^ 
4. What was the climate of the countiy when the freshwater deposits 
took place at Hordell? — Your constant reader, W. B. H., Lymington. 
1. The Hampshire basin was not an isolated area, but continuous with 
the London basin ; the deposits in the two areas differing according to 
depth of sea, presence of rivers, etc. The uprise of the chalk hills took 
place probably during some portion of the Pliocene period. The New 
Forest district, as now existing, has been covered either by the sea or by 
a lake in the Pleistocene period. 2. In the Pleistocene period. 
3. Yes ; during the Middle Eocene period Paplotherinm, Palceotherium, 
and others, existed with Hycenodon, in the western European area. 
4. Probably much warmer than at present — subtropical.
