loured, frequently pale or flesh-coloured, ornamented with fuscous, 

 fulvous, or dark red spots and angular streaks ; spire short, obtuse, 

 with a papillary granose apex, having the appearance of being trun- 

 cated, volutions 6, the 2 or 3 last generally crowned with thick spines 

 or tubercles, sometimes almost miarmed ; aperture oblong, slightly 

 sinuated and acuminated posteriorly, margin of the outer lip pos- 

 teriorly subangular, sharp behind the angle, anteriorly rounded, 

 thick ; columella with 4 distinct folds. 



Referring to Zoological Journal, vol. ii. p. 31, where Broderip 

 says, " After a Careful examination of a connecting series of speci- 

 mens, I am unable to discover any satisfactory specific distinction 

 either in V . pell'is-serpentis, in V. mitis, or in V. serpentina, Lam.; nor 

 do I think that any sufficient cause exists for removing them from 

 the sitimtion they formerly occupied as varieties of V. Vespertilio, 

 Linn.," we think we need merely add that our own opinion coincides 

 entirely with his ■ we have therefore regarded them all as varieties 

 of V. 1 espertiUo, and in order to shew the variations of form to 

 which this species is subject, we have given ten figures representing 

 the principal varieties, thus om' figures 15, 16, 21, 22, represent 

 Lamark's V. Vespertilio; our figures 17, 20, the Y.pellAs-serpentis, 

 Lam.; our figiu'es 19, 23, light and dark coloured specimens of 

 Lamarck's J . serpentina, and our figure 18 shews his V. mitis. 



23. Yoluta angulata (pi. xlvii. f. 13, 14.), Swains. ; Y. Du- 

 fresnii, Donovan, Nat. Hep., vol. ii. pi. lxvii. (1S24.) 



Testa oblonga, fusiformi, epidermide vitrea tecta, pallida, lineis 

 irregidaribus eastaneis longitudinaliter undata; spira breviuscula, 

 acuminata, apice acutiusculo, anfractibus 5 ad 6, duobus ultimis 

 postice angulatis, pone angidmn planis, ultimo maximo ; apertura 

 oblonga, postice angulata, antice, effusa, pallide am'antiaca; colu- 

 mella triplicate, antice acuta, plica postica obsoletiori. 



Shell oblong, fusiform, covered with a shining epidermis, of a 

 pale colour, with irregular midulated longitudinal chesnut lines; 

 sphe rather short, acuminated, with a rather acute apex ; volutions 

 5 to 6, the two last angular posteriorly, and flat behind the angle, 

 the last very large ; aperture oblong, posteriorly angular, anteriorly 

 effuse, pale orange coloured ; columella with three folds, the ante- 

 rior of which is sharp, and the posterior rather obsolete. 



This was published many years since by Swainson under the name 

 of angulata, but it has lately been republished by IS agner under 

 the appellation of V. nasica : of course Swainson's name has the right 

 of priority, though the apex is sometimes extended in a manner so 

 remarkable as fully to justify the latter name.
