and regarding the columella to be truly plaited, placed 
the species among the Mitres in their genus Voluta. 
Species 53. (Mus. Cuming.) 
Achatina Latteei. Achat, testa cylindraceo-oblonga, 
Volvariceformi, spird brevi, anfractibus septem, convexo- 
planis, l (embus, cuticulam carneam politam indutis, 
columella contorta, lira callosa marginata, aperturd 
elongate, angusta; fulvd, rufo-brunneo longitudim- 
liter subremote strigatd. 
Lattee’s Achatina. Shell cylindrically oblong, Vol- 
varia-shaped, spire short, whorls seven in number, 
convexly flattened, smooth, covered with a polished 
homy cuticle, columella twisted, edged with a callous 
ridge, aperture elongated and narrow ; fulvous, lon- 
gitudinally rather remotely streaked with red-brown.

Hab. Central America ; Lattre. 
The shell of this species approaches the form of Volvaria 
or Tornatella, though totally unconnected with those 
genera ; the columella is not, however, plaited, but elevated 
at the base into a callous ridge, as in the Achatina columna. 
The entire surface of the shell is covered with a perfectly 
transparent polished horny cuticle, through which the dark 
stripes show with additional lustre. 
It is a rare and extremely interesting species, collected 
by M. Lattre in Central America, probably in the province 
of Vera Cruz, and named by Dr. Pfeiffer in honour of that 
eminent traveller. 
Species 54. (Mus. Dennison.) 
Achatina nigeicans. Achat, testa oblongo-ovatd, soli- 
diuscula, anfractibus septem, contexts, superne subtiliter 
concentrice striatis, delude lavibus, cuticulam corneam 
politam indutis, columella brevi, contorta, alternate 
truncatd, aperturd oblongd, labro medio subdilatato ; 
livido-nigrd, suturis basique fulvis, stiigis fulvis per- 
paucis longitudinalibus notaid. 
The blackish Achatina. Shell oblong-ovate, rather 
solid, whorls seven in number, convex, finely concen- 
trically striated round the upper part, then smooth, 
covered with a polished horny cuticle, columella short, 
twisted, attenuately truncated, aperture oblong, lip 
slightly dilated in the middle; livid-black, sutures 
and base fulvous, marked with a very few fulvous 
streaks. 
Pfeiffer, ( Glandim ,) Pro. Zool. Soc., 1845. p. 75. 
Hab. Vera Cruz, Central America; Lattre. 
An interesting species, covered with a transparent 
cuticle of the same highly glazed character as the pre- 
ceding, from the same locality, more swollen in form, and 
of a peculiar dark beetle brown or black. 
Species 55. (Mus. Cuming.) 
Achatina voluta. Achat testa subcylindraceo-oblonga, 
oleaced, solidiusculd, spird brevi, anfractibus septem, 
subplano-convexis, lavibus, cuticulam corneam politam 
indutis, columella brevi, arcuata, abrupte truncatd, 
aperturd elongata, angusta, labro medio subdilatato ; 
olivaceo-brumescente, subindistincte longitudinaliter 
strigatd. 
The volute Achatina. Shell somewhat cylindrically 
oblong, olive-shaped, rather solid, spire short, whorls 
seven in number, somewhat flatly convex, smooth, 
covered with a polished homy cuticle, columella short, 
arched, abruptly truncated, aperture elongated, nar- 
row, lip slightly dilated in the middle ; light olive- 
brown, somewhat indistinctly longitudinally streaked.

The above species may be regarded as the type of this 
shining horn-clad group. Though of rare occurrence, it is 
admirably figured in vol. ix. of the Conchy lien Cabinet, pub- 
lished in 1786.

The St. Domingo Achatina. Shell fusiformly oblong, 
whorls seven in number, convex, somewhat rounded
