Cestodes, Brimley, 1938

ethanol. Cestodes were stained with Semichon’s carmine or Delafield’s hematoxilin and mounted in Canada balsam. Histological sections ( 15 mm) were stained with hematoxylin and eosin. Terminology for hooks and armature types is that proposed by Dollfus (1942), Campbell & Beveridge (1994), and Beveridge & Campbell (1989), respectively. The classification used herein is that of Campbell & Beveridge (1994), and of Palm (1999) for Tentaculariidae . Paratypes of P. dollfusi Carvajal & Rego, 1983 , deposited in the Helminthological Collection of the Instituto Oswaldo Cruz, Rio de Janeiro, Brazil (CHIOC 32018 b-d), were examined for comparison. Drawings were made with the aid of a drawing tube. Descriptions, measurements, and drawings are presented for those species for which systematic and/or morphological knowledge are/is incomplete. Measurements were made either with an ocular micrometer or a digital image system using the program Sigma Scan Pro (Jandel Scientific Software) and are presented in mm, unless otherwise indicated in the respective descriptions; the mean and standard deviation (±) is presented followed by the range in parentheses when more than two specimens are available.
