22 Marhie Investigations in South Africa. Vol. V. 



plate (fig. 21) with bilobate hook and some small denticles on the 

 margin of the outer lobe ; on the following plates (figs. 3, 4) the 

 outer lobe had become a coarse denticle ; on the following one, two, 

 or mostly three, rather blunt denticles on the hook (figs. 5, 6) ; 

 sometimes the denticles failed on some plates, or four were seen 

 (fig. 6) ; on the 3-5 outermost plates denticles were not seen 



(fig. 7)- 



The long white salivary glands, 12-14 mm. in length by a breadth 

 of 0'5 mm., as usual, and reaching backwards to the masticatory 

 stomach. 



The CBsophagus 8-10 mm. long, its hinder part sometimes dilated 

 into a first stomach of a length of 4 by a breadth of 6 mm. The 

 masticatory stomach 5-9 mm. long by a diameter of 9-10 ; it showed, 

 arranged in the usual way, 8-10 larger pyramids, in the cardiac part 

 moreover 6-4 smaller and more irregular, 8-7 more conical ; or 10 

 larger and 8 smaller, in all 22-21-18 stomachal teeth. The larger 

 were up to 4 mm. high and their base also to 4 mm. broad ; they 

 were brownish yellow, cartilaginous, translucent, and showed the 

 common finely iridescent axial or subaxial column. The third 

 stomach 8-12 long. The intestine as usual. — The liver dirty 

 brownish yellow, 2-3-3 cm. long by a breadth of 1 •5-1-6, reaches 

 a height of l-4-l'5 ; it was short-sausage shaped, by the windings 

 of the intestine superficially divided in several longer or shorter 

 lobes united with each other. Anteriorly beside the intestine a 

 little biliary cavity was found, with several openings in the pyloric 

 part of the third stomach ; no proper biliary bladder was seen. 



The pericardium was large. The ventricle of the heart 5 mm. 

 long, the crista of the truncus aortas pellucid, 2 mm. long. 



The whitish small hermaphrodite gland 6-7 mm. broad by a 

 length of 5-3 and a thickness of 2 ; in its lobes ripe genital 

 elements ; its duct in coils wound between the lobes of the liver 

 to the inside of the anterior genital mass (fig. 2a). This latter 

 whitish and yellowish white, in length measuring 10-15 mm. to the 

 vulva by a height of 5-6 and a thickness of 2-3 mm. The proper 

 (fig. 2b) muco-albuminous gland convex-plain, on its upper margin 

 the pellucid pear-formed spermatocysta of a length of 3 mm. (tig. 2c), 

 opening with its duct in the root of the sperm-oviduct. The gland 

 is continued in a nearly cylindric tube, a little longer than the gland 

 itself, the sperm-oviduct (fig. 2d), on sections it is seen divided into 

 two parts of unequal size by a strong fold or partition-wall ; in the 

 lower part the sperniatotheca seems to open. This latter (fig. 2c) 

 lies before the heart, on the hinder end of the stomach ; it was 

 globular, yellowish, of a diameter of 4 mm. ; its duct a little longer
