A very pretty little shell, coloured with two clearly defined 
linear bands on each whorl. The whorls, particularly the 
upper ones, are very obliquely coiled; with the exception 
of the apical ones they are finely, spirally grooved. The 
nucleus is small, pellucid, and, as in the genus Turbonilla, 
sinistral. 
Triforts abnormalis, sp. n. 
Testa dextrorsa, elongato-pyramidata, fusca; spira vix conyexa, 
apice obtuso ; anfractus 12, primi 2 obtuse rotundati, corrugati, 
ceeteri supra planati, vix concavi, infra biangulati, undique 
longitudinaliter irregulariter rugose plicati, liris numerosis 
ineequalibus dense granosis spiraliter cingulati; anfractus ulti- 
mus 4 longitudinis teste paulo superans, infra medium valde 
concavo-contractus ; rostrum breve, tubiforme, leviter recurvum ; 
apertura patula, intus fusca, margine columellari tenuiter elevato, 
leviter reflexo, dextro crenulato, ad canalem transcolumellam 
incurvo. 
Long. 14, maj. diam. 5 millim.

There can be little doubt that this is really a dextral 
species of Triforts. It is not very far removed from 7. per- 
versus, Linn., excepting in the inequality of the nodules and 
the prominence of the ridges below the middle of the whorls. 
The canal, as in most of the Trifort when adult, is separated 
by the outer lip passing over and almost uniting with the 
columellar margin. 
Nerita proxima, sp. n. 
Testa oblique ovata, fulva, nigro-fusco variegata, spira parva, 
abbreviato conica, conyexa; anfractus 4 conyexi, oblique sub-
