Described in Zool. Jahrb. Bd. 13. 1900. p. 407. The position of 

 the testes, ovary, uterus and vitellaria certainly entitle it to be con- 

 sidered with the Telorchis group. The long distance between ventral 

 sucker and genital pore, but especially the position of the latter, are 

 important differences. Upon renewed examination I am convinced 

 that the penis-sac and vagina cross under the left coecum and open 

 on the dorsal surface, and that the exserted penis lies above the body. 

 There is a j)repharynx. The vitellaria do not extend so far in front as I 

 indicated in the drawing. The largest eggs measure 0,042 X 0,021 mm.

New genus: aw'is^ ear. Described in Zool. Jahrb. 13. Bd. 1900 

 p. 406. The ear-like, lateral projections of the mouth-sucker suggest 

 Ehytidodes and Calycodes of Loo s s and Cotylotretus of dim er, 

 which the animal also resembles in its lengthened form, the testes being 

 near the middle of the body, the long coeca, the uterus confined to a 

 short region behind the sucker. Sections of the worm that was figured 

 in my earlier paper show that the vitelline glands are not confined 

 outside the coeca but continue from one side to the other, both above 

 and below the coeca and excretory duct, and that they extend as far 

 forward as to the posterior edge of the ventral sucker. The anterior 

 follicles are not so numerous and are more difficult to distinguish 

 from groups of sub-cuticular and gland cells. The position of the 

 ovary, close behind and to the right from the ventral sucker, is an 

 important distinction. Another is in the large median trunk of the 

 excretory system, lying above the testes and dividing at the posterior 

 boundry of the ovary, its lateral divisions rapidly narrowing. The 

 Laurer's canal extends up in the crotch of the excretory duct and 

 opens in the mid-dorsal line by a conspicuous thick-walled opening. 

 There is a large penis-sac' The egg is elliptical and measures 0,031 

 X 0,017 mm. There is no apparent pre-pharynx or oesophagus. The 

 oral and ventral suckers measure 0,307 X 0,276 and 0,230 X 0,199 

 in breadth and depth. The cuticle contains numerous fine scales.
