136 THE NAUTILUS. 



ies with equally interesting ones from, as it would seem, his 

 very back yard. 



The reason for all this is obvious. Havana province is all 

 limestone and the mountain system that once occupied it and 

 developed its rich fauna is now reduced to a number of isolated 

 lulls, — large, small and tiny, each standing alone and harboring 

 a little faunula of its own of more or less modified species. One 

 of the larger of these hills is in the northwest corner of the 

 province (near Guanajay) and hardly an hour's ride by trolley 

 from the city of Havana. It is about five hundred feet high, 

 about a mile long, of limestone and well wooded. Its name is 

 " Loma de Anafe," — the word "loma" meaning hill. Barring 

 a few dead shells gathered there recently and sent to Dr. Torre 

 by a friend, I know of no mollusk records from it. Out of 

 curiosity, and in a holiday spirit, I visited it last fall. The 

 morning was given to the south side and the base; the afternoon 

 to the top and to a deep gorge that fairly splits the hill on the 

 north side, — called La Barranca. Within the deep gorge, with 

 its precipitous walls and lush tropic vegetation and its generally 

 wild aspect, it is hard to realize that the smoke of Havana is in 

 sight above the eastern horizon. 



The following list of land-shells from Anafe show a very 

 typical Havana province assembage of names with just a sug- 

 gestion of Pinar del Rio in the Chondropoma ottonis. Those 

 with a " B" indicate the Barranca, or gorge, of the north side, 

 while "S " indicates the south front :

Thysanophora selenina Gld. (S). 



Thysanophora saxicola Pfr. (S). 



Thysanophora stigmatica Pfr. (B).
