Material examined : 2 ovig. females, MNRJ 17890, Brazil , Atol das Rocas , northeast part of atoll, between Barretão and Barretinha, Pedra de Tartaruga, in calcareous algae, depth 10 m , coll. F.B. Pitombo and R. Barroso, 24 Dec 2000 [ 1 specimen dissected]; 1 ovig. female, MNHN-Na 13626, Brazil , Fernando do Noronha, coll. Rallier du Baly, 1913. Description : See Manning & Chace (1990) . Colour : Unknown. Size : The larger of the two AR specimens has CL 3.1 mm , TL 8.7 mm ; the specimen from Fernando do Noronha has CL 3.7 mm , TL 10.2 mm . CL of the Ascension specimens ranged from 1.2 to 2.0 mm ( Manning & Chace, 1990 ). Ecology : The specimens from Atol das Rocas were extracted from crevices in calcareous algae that were collected at a depth of 10 m . The type series from Ascension Island was collected in tide pools (probably under rocks or among calcareous algae). FIGURE 5.
