 - Pterodrilus n.g. (Discodrilidae s. Brancbiobdellidae). „ . . cfiaracterized by the 

 presence on certain of the post-cephalic somites of paired dorsal appendages, 

 chiefly developed from the muscular layers of the body walls. The genus 

 resembles American Discodiilids hitherto described in the presence of a 

 second pair of vasa(e) deferentia(e) in the VI** 1 pcst cephalic somite, in 

 addition to the pair in the V tl1 somite, which alore is present in the 

 European Branchiobdella. Both pairs open to the exterior in the VI th 

 somite by the usual form of efferent apparatus. The dorsal and ventral 

 cuticular javvs are similar to one another, and each is normally bi-!aterally 

 symmetrical, though not infrequent variations affecting this symmetry are 

 notable. The external openings of the anterior pair of nephiidia are united 

 in a common muscular vesicle having au outlet on the dorsum of somite
