* Naturalized Species. 
1. B. Goodallii. — A subperforated, turrited, pellucid, pale, 
corneous or almost white shell, having from six to seven volu- 
tions, and an ovate aperture.” 
“ Helix Goodalli,” Miller., Ann. Phil. xix. 381. — Pine-beds, Bristol. 
Length upwards of ,%ths of an inch ; the whorls rather flat, sometimes 
eight in number ; separating line distinct ; finely striated across by waved 
lines of growth. This is the CocMicella clavulus of Ferrussac. We are in- 
debted to Mr Miller for publishing a notice of this curious species. Mr 
Thomas Drummond, in a letter now before me, says, “ The Helix Goodallii 
was first pointed out by me in 1816, when I was in the habit of feeding 
them, and when I wanted a supply, I merely placed a flat board upon the 
surface of the tan, and left two or three small worms beneath it (dead ones 
of course), and 1 never saw it fail of being covered with them in a few days.” 
2. B. decollatus. — Shell subcylindrical, truncated at the apex. 
Buccinum album clavicula productiore fere abrupta. List. Conch, t. xvii. 
f. 12. — Bui. decoU. Drap. Moll. 76. 
Dr Turton gives the following notice respecting this species : Bulimus 
decollatus was observed to breed in great abundance, for many successive 
years, in the green -house at Watton, in the south of Devon, the seat of H. 
Studdy, Esq., lodged in the earth, under the wood-work, whence they wan- 
dered abroad in the summer. This wood-work and the earth were removed, 
and replaced with stone, by which the colony was lost ; and all that were 
preserved we owe to the care of Mrs Grifiiths and Miss Hill.” — Zool. Journ. 
No. viii. 565.
