Figure*. 



Achatina regina. PI. H. Fig. 3. Showing the resemblance of its ani- 

 mal to that of Bulimus oblongus figured above, notwithstanding the 

 generic difference in the shells. 



Achatina zebra. PI. 20. Pig. 110. A small example of the West 

 African type of the genus, showing the truncated columella of the 

 shell, and thin, unreflected lip. 



Achatina (Spiraxis) nigricans. PL 20. Fig. 111. Shell illustrative 

 of the section of polished horny texture, chiefly inhabiting Central 

 America. 



Genus 5. ACHATINELLA, Swainson. 



Animal ; with four tentacles, the upper ones clubbed at the end, 

 elongated and eyed, the lower ones short and slightly clavate ; 

 surface of the body covered with numerous granulations ; foot 

 long, narrow, tapering behind. (Newcomb.) 



Shell ; rather small, conical, sometimes turreted, dextral or sinis- 

 tral, imperforate, or only very slightly umbilicated ; whorls six 

 to seven in number, very rarely sculptured ; columella short, 

 mostly callously twisted ; lip rather thickened, rarely refected. 



The numerous series of gaily painted shells, which constitute this genus, 

 are rather similar in character, and they are mostly of an uniform small 

 size. The most striking feature of the group is their very restricted range 

 of habitation. The whole are natives of one isolated locality, the Sandwich 

 Islands, where they take the place of the Bidimi and Achatina of the 

 Continent. None of the Achatinellce appear in the ' Systema Naturse/ The 

 same year in which Capt. Cook discovered the Sandwich Islands, Linnaeus 

 died. Twenty years afterwards, a straggler found its way into the last 

 plate of Chemnitz's ' Conchylien Cabinet/ but where it came from, nobody 

 knew, and it was described as a sea shell, — Turbo lugnbris sinistrorsus.
