chips of wood cemented together.”—‘ Observations in Natural 
History,’ p. 321. 
Achatina acicula.—One or two specimens in a limestone bank 
at Went Hill, June, 1886. 
Since the foregoing notes were written a few other observations 
have been made, as under :— 
Bythinia tentaculata.—In addition to the type and the variety 
ventricosa, an elongate form of this species occurs near Fairburn, 
about five miles from Pontefract. The longest specimen taken 
there measures 14} mill. The length of the short ventricose 
form is 11 mill. 
B. Leachti. — Collected in company with the elongate variety 
of tentaculata, September, 1886. 
Limnea peregra. — One of the specimens mentioned as from 
Methley is scantily hispid. Very few water shells are hispid. 
Planorbis albus is described as being hispid; in fact it was 
formerly called P. hispida, and the young of Paludina vivipara 
are downy. 
Limaa agrestis var. nigra. — One specimen at Newton, near 
Castleford, September, 1886. 
Helix rufescens var. minor.—Featherstone, near Pontefract. 
H. hispida var. depilata ?—Featherstone and Newton.

very few of our readers who have not perused his volumes and 
liked them. The agreeable style in which they are written, 
combined with the variety of information about shooting, fishing, 
and Natural History, which the author had a happy knack of

Mr. Knox was one of those fortunate individuals who had no
