12*. Orthalicus zebra (Miiller). 

 lyidhmis zchrii, Reeve, Conch. Icon. pi. xv. fig. 90, pi. xxvii. fig. 90 h. 



This s})ecics lias received several names, and ranges from 

 ]\In/atlan to Mexico, and Florida, through several of the 

 West-Indian Islands, along the north part of South America 

 into Brazil. 



" It is very common in the neighbourhood of Kingstown, 

 Jamaica, but seems confined to that area, and may be seen 

 clinging in hundreds to the ])riekly-pear plants bordering the 

 roads. I have not met with it in any other part of that 

 island. In 1889 1 brought a small basket full of them from 

 Jamaica to Barbados ; but being on arrival placed in quaran- 

 tine, on Pelican Island, 1 turned them out there on the bushes. 

 Subsequently I found them in limited numbers already intro- 

 duced to gardens in the suburbs of Bridgetown." {Feildeti.) 



13*. Finer ia viequensis (Pfeiffcr). 



Fineria viequensis, Pfeiffer, Novitat. Conch, vol. iii. p. 408, pi. xciii. 

 figs. 39-41 (as Macroceramiis). 



This species, originally described by Pfeiffer as a BultmuSj 

 has only been observed in one other island. It is curious 

 that it lias not been found between Vieque and Barbados. 



" It is not generally sjjread over the island, but appears 

 to be confined to the coral rocks bordering the sea, on the east 

 side in Christchurch and St. Philip parishes." (^Feilden.) 



14*. Stenogyra octona (Chemnitz). 

 Achatina octona, Reeve, Conch. Icon. fig. 84. 



The distribution of this species, like that of Helix similaris, 

 is truly remarkable. It has been found in most of the West- 

 Indian Islands, in several places along the northern parts of 

 South America, at Costa Rica, and in the British Museum 

 there are specimens from Central Africa, near Lake Tangan- 

 yika, and Madagascar, which appear to be inseparable. 



"In Barbados it is very abundant throughout the island, and 

 is met with in colonies under stones and rocks." {Feilden.) 



15*. Stenogyra suhula (Pfeiffer).
