Benham. — Tico New Species of Leech in N.Z. 191 



Tandon ; who, however, according to Blanchard, has confused 

 Limnatis nilotica with Hcetnopis sanguisuga, and describes it 

 under the latter name {loc. cit., pi. vi). 



In this leech the vas deferens is described as of large size and 

 sinuous ; the testes are also relatively large ; the prostate + 

 penis-sac is pyriform, as the penis-sac is very short and straight. 

 In all these respects H. antipodum agrees with Limnatis nilotica, 

 which has a very wide distribution over Asia, south Europe, 

 and north Africa. But Blanchard (1894), in defining Limnatis, 

 says, " Jaws with more than a hundred very acute denticles, 

 and ornamented with papillae ; anterior lip with a ventral 

 groove." In each of these points my species disagrees.
