HISPANIOLAN AND BAHAMAN ANNULARHDAE 39 



trance of a cave at Barrera, Dominican Republic. This locality is in the 

 Province of Azua about i6 miles southwest of the town of Azua, 



Articulipoma, new subgenus 



In the southern half of Hispaniola there occurs a group of medium- 

 sized members of the subfamily Chondropominae that vary in shape 

 from elongate-ovate to broadly ovate, with the color scheme usually 

 flesh-colored, variously marked with spots, dots, or fulgurations of 

 brown, whose elements are usually arranged in more or less axial and 

 spiral series. The distinctive features of this group, however, are the 

 sublamellar, closely spaced, axial ribs rendered vertebrated by low, broad, 

 spiral, tumid areas, which one might call half-cords or depressed half- 

 cords, but their breadth contrasted with their elevation does not justify 

 this designation. 



Type species: Chondropoma (Articulipoma) caroli, new species. 



Practically all our material was collected by Charles Russell Orcutt 

 while working for the Smithsonian Institution in that territory. The 

 hardship that he endured during this campaign was almost superhuman, 

 and it is for this reason that I am bestowing his name upon two of the 

 species belonging here. The following is quoted from one of his letters : 



"My first trip covered the trails from Port-au-Prince to Croix des 

 Bouquets, Gautier, Fond Parisien, Fonds Verettes, Bodarie and Saltrou ; 

 returning from Saltrou up the Gimbi River to the settlement and moun- 

 tain of the same name, Bois Contre, and the pine forests of the Trou 

 Coucan (four districts) to Croix des Bouquets and the point of de- 

 parture. So far it still seems that the territory assigned me is a "lemon" 

 of purest water. Fonds Verettes to Bodarie no shells ; spots from Bodarie 

 to Saltrou and up the Gimbi dry river banks a variety of small shells 

 were found (dead only). After crossing the divide more small shells 

 were found, in part alive, all along the route back to the Plaine du Cul- 

 de-Sac. 



"Along the southern Dominican border it is not safe for a lone trav- 

 eler; out of Fonds Verettes I was attacked after dark and wounded in 

 the forehead with a stone. I bled like a stuck pig but did not lose con- 

 sciousness and rendered first aid; the Negroes nearby put a hut at 

 my disposal and kept a fire burning all night and I resumed my tramp 

 alone the next day to Bodarie. I secured a lot of ferns and mosses in 

 the 'rain forest' before reaching Bodarie. . . ."
