SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 621 
opening or genital pore is situated very nearly in the 
middle of the margin of the proglottis. The penis is almost 
always protruded, and is of moderate length. The vas 
deferens sometimes passes under the ovary, traverses the 
whole width of the proglottis, and communicates with the 
canals which come from the testicle of the opposite side. 
The testicles are formed of spherical cellules, and are situated 
at the lateral margins of the proglottis. On the margin 
which bears the penis there are about thirty-five, on the other 
side, they occupy the whole space externally to the longi¬ 
tudinal canal, and number from forty-five to fifty. The con¬ 
duits from these testicles combine together to form the 
deferent canals which passes to the penis. The female 
organs comprise an ovary and a uterus. Each segment has 
one ovary situated beside the penis at a short distance from 
the longitudinal canal. It is formed by three small cellular 
lobules. The two small external masses, placed close toge¬ 
ther, are formed of small spherical cellules with an egg 
passage at one extremity, which communicates with the se¬ 
minal reservoir. A little behind these two ovarian masses, 
but in contact with them, is another more marked group of 
cellules, which form the albuminous gland. The vaginal 
conduit commences at the swollen extremity of the penis or 
the praeputial swelling, and takes its course to the ovary by 
passing underneath the longitudinal canal. It divides the 
margin of the segment into two very nearly equal parts, 
and separates the testicle from the folds of the deferent canals. 
In the neighbourhood of the ovary it presents an expansion, 
the seminal pouch, which is not always present. The uterus 
commences as a canal, at first straight, afterwards flexuous, 
which passes across the width of the parenchymatous struc¬ 
ture of the proglottis, nearly from one longitudinal canal to 
the other. When it is filled with eggs it stretches as far 
as the borders of the segment, and the testicles seem to 
become atrophied. Thus, says M. Rivolta, to sum up our 
information, the species which has just been described ought 
not to be confounded with the two mentioned at the com¬ 
mencement of this note, and especially with Texpansa of 
the sheep. This last form is distinguished from it inde¬ 
pendently of the length and size of its proglottis, and of the 
greater shortness of its neck, by these rounded spots situated 
at the lateral margins of the segments visible to the naked 
eye (sometimes so even in specimens preserved in alcohol), 
and formed by the ovaries. Its component cellules are more 
developed than in the species which has just been described, 
and the seminal pouch is more voluminous. Finally, the
