GIBBONS: ON W. INDIAN PULMONIFERA. 129 



NOTES ON THE HABITS AND DISTRIBUTION, &c., 

 OF CERTAIN W. INDIAN PULMONIFERA. 



By J. S. GIBBONS, M.B. 



Having lately visited most of the principal ports of the West 

 Indies, I have put together the following notes on the more 

 remarkable species collected, in the hope that, although containing 

 no new facts of scientific value, they may prove of interest as the 

 results of personal observation in the native haunts of the molluscs. 



Giandina solidula, Pfr. Habana and Puerto Plata (San 



Domingo). 

 Hyalina decolorata, Driiet. Georgetown (Demerara). Animal 



a beautiful clear lemon-color ; eggs large, oval, much more 



compressed than those of Stenogyra, with a hard, greenish, 



and almost transparent shell. 



Guppya vacans, Guppy. Trinidad and Georgetown. Although 

 young are not rare, I never succeeded in finding the shell 

 considered by Mr. Guppy to be the adult form. A nearly 

 allied species occurs at Puerto Cabello and Tobago. 



Helix subaquila, Sh. Puerto Plata and St. Thomas. 



H. vortex, Pfr. Habana and St. Thomas. The Cuban molluscs 

 have the tentacles dark neutral or black ; those collected at 

 St. Thomas have the same organs reddish. I am, how- 

 ever, unable to detect any difference in the shells. Animal 

 ovovivi parous. The shell is usually incrusted with dirt, as in 

 some other species of Microphysa. 



H. paludosa, Pfr. Habana. One specimen is an albino variety. 



H. Cubensis, Pfr. Habana. On acacias. The banded variety is 

 of less frequent occurrence than the pure white. 



Bulimus distortus, Brug. Puerto Cabello (Venezuela). Eggs 

 oval, white, calcareous j 5 lines in length.
