transverse diameter of 0°46-0°55 mm. Two of the suckers 
are situated on the dorsal and two on the ventral surface. 
They are of an oval shape, having a diameter of about 
0°3 mm. antero-posteriorly and ot 0-2 mm. transversely. 
The apertures of the suckers are in the form of longitudinal 
slits. The scolex is followed by a narrower unsegmented 
“neck,” which may attain a length of 6 or 7mm. ‘There 
may or may not be a constriction immediately behind the 
scolex. In acomplete strobila some 490 segments can be 
counted. All the segments are broader than long. The

genital organs appear early, and the number of sexually 
mature segments is relatively large. The uterus does not 
become a conspicuous organ until about the 850th segment 
is reached. The disappearance of the male and female 
glands, after the appearance of the uterus, is very gradual, 
and some traces of them remain even in the oldest gravid 
segments observed. 
The subcuticular layer of the body-wall contains large 
numbers of elongated gland-cells, staining deeply with 
hematoxylin. The cortical parenchyme is thick, measuring
