continues for some time, the articulation becom- 

 ing 10, 14, 15, 17 mil. broad, by from 9 to 14 mil. 

 long. This proportion does not remain constant, 

 and then segments are seen from 3 to 4 lines broad 

 by 1 to 1 J inches long. This change of form Kiich- 

 enmeister explains by the fact, that only the longi- 

 tudinal muscles reach from the upper to the lower 

 margin of the segments, while the transverse mus- 

 cles cease at a greater or less distance from the mar- 

 gins. 



The genital openings, unilaterally placed, are large 

 and swollen. The penis is thicker and shorter than 

 is that of the Taenia solium; is 0-316 mil. long, 

 0*031 mil. broad at its apex, and 0-063 mil. at its 

 base, and leads posteriorly into a convoluted seminal 

 cord, from 0-023 to 0-039 mil thick. 



Beneath this is the female genital orifice, strongly 

 marked with pigment, 0*071 mil. at its external 

 orifice, then diminishing to 0*039 mil. in its course; 

 and opens, in the lower third of the segment, into the 

 uterus with a dilatation of 0.079 mil., running first 

 along the lower side and parallel to the seminal cord, 

 until it suddenly bends downwards. 



The uterus is a thick-walled, straight, median 

 canal, with numerous lateral branches, which spring 

 opposite to one another, and run parallel, and per- 

 fectly undivided, into the margins of the segments, 

 when they either terminate in a caecum, or, at the 

 utmost, become furcated ; but do not, as in the 

 Tsenise, divide dendritically.
