Distribution and habitat. Collections at UF enable us to limit Pfeiffer’s imprecise “ In insulae Haiti .” The species is known only from Loma Catalina, an outcrop of the Cordillera Septentrional southeast of Sosuá. Much of this area is contained in the Parque Nacional El Choco. The type locality is herein restricted to the Dominican Republic, Puerto Plata Province, Loma Catalina. Comparison with other species. This species is similar to A. abbotti ( Figure 3 A–E ) but differs in having finer, less serrate sculpture, less developed keels, and a less fluted outer lip. Remarks. This species is perhaps unique among Abbottella in possessing a periostracum although it is lost in most specimens. On fresh examples this periostracum forms short bristles at the junctures of the axial and spiral sculpture. The degree of fluting and serration of the outer lip varies greatly—some specimens show virtually no fluting.
