Body cylindrical in shape, thickerin the middle, tapering towards 

 each extremity, and finely striated across, though the striae are 

 rather distant from each other. Head rather large, cylindrical, 

 about one line in length, thicker than the neck, and separated from 

 it by a distinct line or groove. MoutJi orbicular, placed in the centre 

 of the truncated part ot the head, and surrounded with two horny 

 capsules or bullae, the limbs or margins of which are each armed 

 with a row of numerons teeth. The limb of the external capsule is 

 the larger of the two, and the teeth, though numerous, are less so 

 than in the internai limb, and are stronger and pointed outwards. 

 The limb of the inner capsule is much smaller, the teeth very 

 minute, and exceedingly numerous. This portion of the body does 

 not difïer in the two sexes. The tail of the maie is in the form of a 

 membranous expansion or pouch surrounding this extremity of 

 the body, and is divided into three lobes. The central lobe is the 

 largest, and is supported by seven ribs or rays, three in the middle 

 end two at each side. The three central ribs are dichotomous, and 

 the middle one of thèse bas its two branches sending olî two oj- 

 three short processes, like buds; the two others are simple, Of the 

 latéral ribs (two on each side) the innermost one is dichotomous, 

 the two branches into which it is divided sending otï short pro- 

 cesses or buds; the outer rib is simple. The two latéral lobes of 

 this caudal expansion are smaller than the central one, and are
