Measurements of an ordinary individual.—Length of body mm.; width of body mm.; thickness of body, anterior mm., middle mm., posterior mm.; diameter of nucleus Fig. 179.—Opalina tbrbak-mariae, X 117 diameters. mm. to mm.; cilia line interval, anterior mm., middle mm., posterior mm. In spite of the short, broad form of most individuals of this spe- cies, it still seems to be related to the general ohtrigona group, for some individuals show an obtrigona-like posterior end. It seems a distinct species. OPALINA COPEI, new species. Type.—United States National Museum No. 16586. Host.—Rana copei Boulenger, two infections from Pico Blanco, Costa Eica, W. M. Gabb, collector; of these the type infection is from United States National Museum specimen No. 30654, 42 mm.
