Plate XYIII. 
Species 89. (Mus. Cuming.) 
Achatina subulata. Achat testa cylindraceo-oblonga, 
spird subexsertd, anfractibus sex ad septem, Icevibus, 
nitidis, supremis convexiusculis, reliquis sub-planulatis, 
columella angrnte truncatd, aperturd parviusculd, 
oblong a ; pellucido-corned , lined spirali opacd sub- 
obscura infra suturas. 
The subulate Achatina. Shell cylindrically oblong, 
spire rather exserted, whorls six to seven in number, 
smooth, shining, the uppermost whorls rather convex, 
the lower a little flattened, columella narrowly trun- 
cated, aperture rather small, oblong; transparent 
homy, with a somewhat obscure spiral opake line 
beneath the sutures.

p. 352. 
Glandina subulata, Philippi. 
Helix orysaca, Hang. 
Achatina orysacea, D’Orbigny. 
Hab. Cuba. 
Distinguished from its allied species by a more oblong- 
cylindrical growth. 
Species 90. (Mus. Cuming.) 
Achatina incehta. Achat, testa oblongd, spird oblusius- 
culd, anfractibus quiuque ad sex, subplanulatis, Icevibus, 
nitidis, superne exiliter marginatis, columella con- 
spicue truncatd, aperturd oblongd, superne angustata ; 
pellucido-corned. 
The doubtful Achatina. Shell oblong, spire some- 
what obtuse, whorls six in number, rather flattened, 
smooth, shining, faintly margined round the upper 
part, columella conspicuously truncated, aperture 
oblong, narrowed at the upper part; transparent 
horny. 
Hab. ? 
Of a transparent homy substance, very like A. solidula, 
from which it differs in being more ventricose towards 
the base. 
Species 91. (Mus. Cuming.) 
achatina cylindracea. Achat, testa cylindraceo-ovatd, 
tenuicula, spird brevissimd, conoidea, anfractibus quin- 
que, convexo-planis, Icevibus, politis, columella excavatd, 
lira callosa angustd basi conspicue marginata, aperturd 
superne elongata et angustata, pellucido-corned. 
The cylindrical Achatina. Shell cylindrically ovate, 
rather thin, spire very short, conoid, whorls five in 
number, convexly flattened, smooth, polished, colu- 
mella excavated, conspicuously edged at the base 
with a narrow callous ridge, aperture elongate and 
narrowed at the upper part ; transparent horny. 
Pfeiffer, Pro. Zool. Soc. 1846. p. 31. 
Hab. Tortilla, Central America. 
The structure of this species is similar to that of the 
A. Lattrei, in which the columella instead of being trun- 
cated turns up at the edge, as in the present species, into 
a callous ridge. 
Species 92. (Mus. Cuming.) 
Achatina solidula. Achat, testa cylindraceo-oblongd, 
spird brevi, anfractibus quinque ad sex, subplanulatis, 
Icevibus, politis, superne exiliter marginatis, columella 
brcevi, arcuata, abrupte truncatd, aperturd oblongd, 
superne angustata ; pellucido-corned. 
The rather-solid Achatina. Shell cylindrically 
oblong, spire short, whorls five to six in number, 
rather flattened, smooth, polished, faintly margined 
at the upper part, columella short, arched, abruptly 
truncated, aperture oblong, narrowed at the upper 
part ; transparent homy. 
Pfeiffer, Wiegman’s Archiv. 1840, vol. i. p. 252. 
Glandina solidula, Philippi. 
Hab. Cuba. 
A bright transparent shell of rather stouter growth 
than most of this group. 
Species 93. (Mus. Cuming.) 
Achatina Porto-Hicensis. Achat, testa oblongo-tur- 
rita, anfractibus octo, convexis, Icevibus, politis, lineis 
impressis longitudinalibus subobscure exsculptis, colu- 
mella arcuatd, abrupte truncatd, aperturd parviusculd ; 
cinerascente-cornea, strigis saturatioribus ornata. 
The Porto-Rico Achatina. Shell oblong-turreted, 
whorls eight in number, convex, smooth, polished, 
rather obscurely sculptured with impressed longitu- 
dinal lines, columella arched, abruptly truncated,
