On Mollusca from the Island of Dominica. 419 



LVI. — On the Mollusca collected hy Mr. G. A. Ramage at the 

 Island of Dominica.— Ueiwxt II.* By Edgar A. "Smith. 



A SECOND consignment of specimens collected at Dominica by 

 Mr. Ramage comprises eight species which were not contained 

 in his first collection. They are as follows : — 



1. Hyalinia arhorea, Say, var. ? 



Helix arhorea, Say, Reeve, Conch. Icon. fig. 733. [For further refer- 

 ences see Gouli, Invert. Mass. 1870, p. 396.] 



Hah. North America, Cuba, Guadeloupe. 



The single specimen from Dominica appears to be rather 

 flatter than North-American examples with which I have 

 compared it ; the lines of growth seem to be slightly coarser 

 and the colour darker. These differences, if constant in a 

 series of specimens, would be sufficient to base a new species 

 upon ; but as only a single example is at hand, I consider it 

 advisable to await more material before attempting a decision. 



t2. Helix [Dentellaria) denticus, F^russac. 



3. Bulimus [Leiostracus] liliaceus^ F^russac. 



4. Bulimus [Leiostracus) multijlisciatus, var. 



Three specimens from Dominica are very different in co- 

 louring from the type as figured by Delessert (Recueil. pl.xxvii. 

 fig. 3). They are of a warm reddish-pink colour banded with 

 purple-black. The upper whorls exhibit two bands, one just 

 beneath the suture and the other, a trifle broader, rather 

 below the middle. The body-whorl has a third zone beneath 

 the centre somewhat narrower than the one above it. The 

 fine spiral strise correspond with those of the typical form 

 and the minute pitting of the dark apical whorls is the same. 



5. Bulimus [Thaumastus) exilis, Graelin. 



Three or four varieties in colour occur in the few shells sent 

 by Mr. Ramage. The form also is equally variable.
