anus. — Of the male he does not mention the enormous 

 transparent margins of the genital suckers. Of the middle dorsal 

 shield he says : „retrecie en arriere oü eile n'atteint pas le bout 

 de Tabdomen", but he does not mention that behind this „plaque 

 thoraco-abdominale" there is a third (posterior) dorsal shield. — 



Of the female he 

 says that the epimeral 

 form a V , which is 

 not quite true , for 

 the epimera I in real- 

 ity are free ; between 

 their proximal ends 

 we observe, however, 

 a point-shaped ster- 

 num. Of the legs IV 

 he teils US that they 

 extend beyond the 

 abdomen „de la moitie 

 environ de la longueur 

 du tarse " . Apparently 

 he has meant o f t h e 

 legs themselves 

 (see our fig. 3). The 

 anterior dorsal shield 

 is described by him 

 „comme sur le male" ; 

 the anterior dorsal 

 shield of the male 

 (flg. 8) is less wide 

 than the distance 

 between the legs of 

 the second pair , so 

 that it is flanked by 

 a band of unprotected 

 skin , whereas that 

 of the female oc- 

 cupies the whole 

 Space between legs II; again, posteriorly the shield of the male 

 is deeper excavate than in the female. The posterior dorsal 

 shield of the female is called again „comme sur le male", which 

 is inexact too , for it is not divided in two shields , but covers 

 the whole abdomen ; moreover , quite posteriorly it is provided 

 with a few longitudinal ridges, which in all the females examined 

 by me have the same configuration (see my figure 3). — Of the
