Eeinhardt determined the toothed whales in which Andrea found the worm as belonging to the genus Clymenia {== ProdelpMnus); biit regarding the other hosts he was unable to state anything definite. In one lot of 370 specimens the proportion of males to females was 1:1. The males attained 70""'" in length, the females 90â¢"'. The worms are somewhat similar to "J., simplex," but differ in essential details of the lips and caudal papillae. The lobes of the lips are provided with a dentigerous ridge, are narrower, and more distinctly separated from the rest of the lip (see fig. 31) than is the case in A, simplex. Nine or ten pairs of postanal papillae are found on the tail of the male (fig. 32). Of these. Fig. 38 Kg. 38. Kg. 40. generally three pairs, occasionally two pairs, are conical and near the tip. The other seven pairs are shorter and situated near the cloaca. The numerous praeaual papillae are conical and arranged on each side in three rows, well separated from one another, those situated nearer the cloaca being shorter and more irregularly arranged. Drasche (1883, pp. 109-111), evidently overlooking Krabbe's paper, reexamined Diesing's original specimens. He found one male with the umbrella-like structure on the head, as described and figured by Diesing, one worm without the head, and two which plainly showed three lips. Upon closer examination he found that the umbrella-like structure on the head was simply a portion of the mucosa of the host. Upon the removal of this
