Olandina siihulata, Philippi. 

 Helix on/saca, Kang. 

 Achatinn orysacea, D'Orbigny. 



Hab. Cuba. 



Distinguished from its allied species by a more oblong- 

 cvlindrical growth. 



Species 90. (Mus. Cuming.) 



Achatina incerta. Achat, testa oblongd, spird obtmim- 

 culd, anfractibus qiduque ad sex, subplamdatk, Icevibus, 

 nitidis, superne exilUer marginatis, columelld con- 

 spicue truncatd, aperturd oblongd, superne angustatd ;

The doubtful Achatina. Shell oljlong, 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 horny substance, very like A. solidula, 

 from which it differs in being more ventrieose towards 

 the base. 



Species 91. (Mus. Cuming.) 

 achatina cylindracea. Achat, testa cglindraceo-ovatd, 

 tenuiculd, spird brevissimd, conoided, anfractibus quin- 



que, cunwxo-planis, lavibus, politis, columelld e.vcamUu, 

 lira callosd angustd basi conspicue marginatd, aperturd 

 suqiernii elongatd et angustatd, pellucido-corned. 

 The cylindrical Achatina. Shell eylindrieally ovate, 

 rather tliin, spire very short, conoid, whorls five iu 

 number, convesly 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. Soe. 1840. p. 31. 

 Hab. Tortilla, Central America. 



Tlie struetui-e of this species is similar to that of tlie 

 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 93. (Mus. Cuming.)

 spird brevi, anfractibus quinque ad sex, subplanulatii, 

 Icevibus, politis, superne exiliter marginatis, columelld 

 brtsvi, arcuatd, abrupte truncatd, aperturd oblongd, 

 superne angustatd ; pellucido-corned. 



The rather-solid Achatina. Shell cyKndrieally 

 oblong, spire short, whorls five to six iu number, 

 rather flattened, smooth, polished, faintly margined 

 at the upper part, columella short, arched, abruptly 

 truncated, aperture oblong, narrowed at the upjier 

 part ; transparent horny. 



Pfeiffer, Wiegman's Archiv. 184-0, vol. i. \i. 353. 

 Glandiiia solidula, Philippi. 



Hab. Cuba. 



A bright transparent shell of rather stouter growth 

 than most of this group. 



Species 93. (Mus. Cuming.) 



Achatina Porto-Ricensis. Achat, testd oblougo-tur- 

 ritd, anfractibus octo, convexis, Icevibus, politis, lineis 

 impressis longiludinalibus subobscure exsculptis, colu- 

 melld arcuatd, abrupte truncatd, aperturd parviusculd ; 

 cinerascente-corned, strigis saturatioribus ornatd.
