This species inhabits the neighbouring islands of St. Vin- 

 cent, Tobago, and Trinidad, and it extends along the northern 

 parts of South America from New (Irauada to J5razil. It is 

 stated by Bland t that it was introduced into Barbados from 

 St. Vincent by the Rev. J. Parkinson.

I have compared the types of JJ. harhadensis with spe- 

 cimens of this species, and they appear to be inseparable. 

 Pfeiffer's term '' solidiuscula " is somewhat misleading, for, 

 although one of the three specimens in Cuming's collection is 

 a little less delicate than usual, the other two arc normally 

 thin.

This species is closely allied to JJ. toiuissiinuSj but is some- 

 what different in the proportional size of the whorls, the last 

 being smaller than that of the species referred to.

This species occurs on several of the adjacent islands and 

 also on the mainland in Guiana. " It is very common 

 throughout the island, under stones, and clinging to the 

 trunks of trees, and the branches of shrubs in gardens."
