NERBUDDA DISTRICT. 213 



So far, therefore, as Dr. Spry's observations go, they are clearly in 

 favor of the view that these trees grew on the spot where the remains of 

 them are now found ; that the bed in which they occur is only a conti- 

 nuation of the same limestone or calcareous band, the out-crop of which 

 may be traced along the base of the trap hills in the neighbourhood. 

 Capt. Nicolls, in a subsequent paperfaj takes exception to Dr. Spry's 

 statement that these vegetable remains rest on limestone; but, from the 

 general tenor of Dr. Spry's remarks, and from his description of the bed 

 as soft, and made up of trap debris, it is highly probable that the word 

 on was a mis-print for in. The bed, probably does not, at the spot where 



abundant and widely distributed species, which occurs in these beds. A fine spe- 

 cimen with the shell intact, from Ellichpur, of five whorls, measures 2.55 — 1.65. 



2. Physa Prinsepii, var. (elongata). At Gujri a very marked variety occurs, with an 



elevated and elongated spire, and seven whorls. Making a trifling allowance for 

 broken top, it measures 2.88 — 1.50. 



3. Physa Hislopiana (n. s.) A small species very numerous at Goraha. A speci- 



men in black chert, of 4£ whorls, measures 0.40—0.23. 



4. Physa tumida (n. s.) A more rounded species than the last, and also a little 



larger. It is very common at Pulsagur ; one specimen measures 0.45 — 0.30, but 

 some occur one-third larger. 



ACHATINA. 



1. Achatina Medlicottiana (n. s.) Shell elongate, spire blunt. A single specimen 



sent from Butara, whorls 5, — 0.36 — 0.15. 



2. Achatina Hislopiana (n. s.) An elegant elongate shell from Goraha; slender, 



whorls 7. 0.35—0.08. This perhaps belongs to the Spiraxis group of the Bulimi. 



3. Achatina conica (n. s.) An elongate species common about Nagpur, whorls 6. 



0.60—0.15. 



4. Achatina tumida (n. s.) A pretty little species common at Telankheri; inter- 



mediate in form between Lymnsea Hislopiana and L. elegans. The separation 

 of this from the genus Lymnsea is rather doubtful. A large specimen of 6 whorls, 

 measures 0. 50 — 0. 1 5. 



5. Achatina pusilla (n. s.) A minute species of 4 or 5 whorls, of which but a single 



specimen was found near Goraha — 0.20—0.06.
