12*. Ortlialicus zebra (Miiller). 

 Bulimus zebra, Reeve, Conch. Icon. pi. xv. fig. 90, pi. xxvii. fig. 90 b. 



This species has received several names, and ranges from 

 Mazatlan 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 prickly-pear plants bordering the 

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

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

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

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

 Subsequently I found them in limited numbers already intro- 

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



13*. Pineria viequensis (Pfeiffcr). 



Pineria viequensis, Pfeiflfer, Novitat. Concb, vol. iii. p. 408, pi. xciii. 

 figs. 39-41 (as Macroceramus). 



This species, originally described by Pfeiffer as a Bulimus^ 

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

 that it has not been found between Vi^que and Barbados. 



" It is not generally spread 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 northei-n parts of 

 South America, at Costa iiica, 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 subula (Pfeiffer).
