SMITH : NON-MAEINE MOLLTTSCA OF ST. VINCENT. 307 



already been described as distinct species : OHhalicus oMuctus, 

 Shuttleworth ; Bulimus melanochilus, Valenciennes ; Achatina pulchella, 

 Spix ; £ul. princeps, Broderip ; B. undatus, Bruguiere ; Zehra Mulleri, 

 Chemn., etc. It ranges from Mazatlan to Mexico, Panama, and 

 Florida, along the northern parts of South America, and through 

 several of the West Indian Islands, namely, Cuba, Jamaica, Cariacou, 

 Grenadines (Rawson), Barbados, and Trinidad. How far its occurrence 

 in some of these localities may be due to human agency, it is impossible 

 to show. In speaking of this species in his paper on the fauna of 

 Trinidad, Mr. Guppy^ refers to a form of it "described by Guilding 

 as B. tindulatus.''^ I have not succeeded yet in finding a description 

 by Guilding of any species bearing that name, except the preceding, 

 which has no relationship with Orthalicus zehra. It seems to me, 

 therefore, nearly certain that some mistake has crept in here.

Hal. — "In umbrosis Sti. Yincentii sub lapidibus " (Guilding). 

 " Open or shady places, under rubbish ; sometimes in the forest, below 

 1,000 feet, but generally near the sea. Common principally about the 

 southern end of the island, and on the windward side." (H. H. Smith.) 



This species was also collected by Mr. H. H. Smith at Grenada. 

 According to Guppy (Proc. Scient. Assoc. Trinidad, vol. ii, p. 166), 

 it also occurs in St. Lucia and Martinique.

Hah. — St. Vincent (Perussac). 



This species is well known to inhabit Dominica, but its presence in 

 St. Vincent requires confirmation.

Sah. — St. Vincent (Guilding). 



This species has also been quoted from Guadeloupe, Dominica, 

 Trinidad, etc.; "these records, however, are mostly worthless, 

 being based on a supposition that almost any Veronicella found in the 

 "West Indies might safely be dubbed occidentalis " (Cockerell, 

 Conchologist, vol. ii, pp. 219, 220).
