proper. Anterior suchcrs of moderate size, nearly circular. Posterior 

 sucker .slightly elliptical, with its major axis coinciding' with the 

 median line of the body j witli a diameter equal to the breadth of the 

 body at the plane of the mouth ; with its internal surf:ice divided into 

 areas like those of T. orale and T. foliaceum. Hooks in one pair, in a 

 position similar to that in the two species just mentioned, long, 

 slender, slightly curved, witli a narrow cavity in the interi(^r, 0.18 mm. 

 long. ]\[outli small, a little in front of the plane of the hinder end of 

 the anterior sucker, riianjux elongated, with a constriction at the 

 middle of its length as in T. orale and T. folicaceiuu. Oesopluajus 

 very short. Intestinal tnntks C(mtinuous behind just in front of the 

 posterior sucker, enclosing an area of a similar form to that of the 

 body, but with the posterior commissural limb straight ; with nume- 

 rous, dendritic branches on the outer side and with a few short, 

 simple branches on the iinier. Conuncju (jenital opening a little behind 

 the anterior sucker of the left side. I'enis short and small, club- 

 shaped. Orarij in the hinder part of the anterior half of tlie b(jdy 

 proper, irregularly globular, not loljed. (Jriditct arising from the front 

 end of the ovary, thence proceeding forwards witli a slight winding or 

 tw(^, and soon continued into the ootyp. Uterus of moderate length, 

 opening into the genital atrium at a short distance from its external 

 pore. Vitellarium ])resent not only in the lateral regions and the anterior 

 lobe of the body but also on the whole dorsal side of the posterior two- 

 thirds of the median region enclosed l)y the intestinal trunks; but in the 

 latter region the lobes are more sp'arsely distriljuted than in the 

 former. Paired yolk-ducts formed as usual by the union of large ducts 

 coming fn^m the anter i(3r and the posteri(3r part. Yolk-reservoir and 

 impaired yolk-duct as usual. Vagincd opening a little behind the common 

 genital opening but nearer the median line ; ragimd caned proceeding, 

 as usual, ])ackwards and inwards with numerous convolutions, forming
