gibbons: on w. Indian pulmonifera. 131 



S. Dunkeri, Pfr. Puerto Plata. Ovovivi]"arcus. T tried in vain 

 to tempt this animal with pieces of meat ; a Glandina 

 solidula placed in the same tumbler greedily ate up the 

 meat. 



Stenogyra micra, D'Orb. Puerto Plata, Barbadoes and smaller 

 Islands to Trinidad, Spanish Main. Animal carries the shell 

 semi-erect, instead of dragging it along as do other species 

 of Stenogyra ; the eggs, too, are different in shape, are pro- 

 portionately smaller and nearly transparent. Puerto Cabello 

 specimens are very strongly lamellate. 



S. octona, Ch. Habana to St. Thomas, thence down Lesser 

 Antilles and all along the Spanish Main. Another species, 

 S. octonoides^ D'Orb, has a similar distribution. I did not 

 find either at Vera Cruz. 6". octona is by far the most 

 common West Indian land shell, it varies considerably ac- 

 cording to locality. The animal contains eggs all the year 

 round, in fact it seems never without them; in some instances, 

 if not always, the young are hatched in the animal. 



Cylindrella Trinitaria, Pfr. Trinidad and Sabanilla (New 

 Grenada). Common in several places about Port-au-Spain; it 

 is rarely decollated. I found specimens of awell marked variety 

 much more solid than the type, nearly twice the breadth, 

 and more spindle-shaped. At Sabanilla a slight variety is 

 abundant, intermediate between the last and typical shells, the 

 ribs, moreover, are lighter in color, making the shell unusually 

 handsome. 



Pupa fallax, Say {= F. Farraiana, D'Orb.) Habana, Puerto 

 Plata, Spanish Main. Cuban specimens differ more from 

 Cartagena shells than frc.m the North American type. 

 Examples found at Curasao and Cartagena are broader, 

 thicker, and darker in color than those from Puerto Cabello 

 ' and the islands.
