18 Marine Investigations in South Africa. Vol. V. 



Behind these plates 10 somewhat smaller followed, mostly rather 

 compressed, more irregular, yellow, of a height of 4-6 mm. Behind 

 this stomach, in the mouth of the second, more thin-walled gray 

 stomach, were seen about 5 series of rounded small papillae, each 

 with a pointed, straight, yellow prickle of the height of 2-2"5 mm. 

 (fig. 20) ; papillae of the same kind, mostly without horn, were 

 scantily distributed over the stomach. The abundant content of 

 the stomachs was fine paunce mixed up with vegetable substance 

 (different algae), parts of small worms, and some foraminifera and 

 small Rissoa-like shells. The dirty gray intestine makes a large 

 superficial curve in a furrow of the liver and ascends to the anus ; 

 its diameter 7-9 mm., its wall thin, its abundant contents the same 

 as in the stomachs. 



The large liver dirty and dark greenish gray, 5 cm. long by a 

 breadth of 4 and a height of 3*8, superficially 3-lobed by the 

 windings of the intestine ; its mass compact, with a small cavity. 

 In front, immediately behind the second stomach, opens the bent, 

 horn-shaped gall-bladder, contrasting by its milk-white colour with 

 the liver, of a diameter of 4 mm., with about its half freely projecting 

 on the under side of the liver. 



The bright yellowish white kidney 3 '3 cm. long by a breadth 

 of 2-3 cm. and a thickness of 5-6 mm. 



The yellow- white hermaphrodite gland at the hinder end of the 

 liver convex-plain, 4-5 cm. long by a breadth of 2-5, and a thickness 

 of 2 ; in its lobules ripe genital elements. The thick hermaphrodite 

 duct in corkscrew windings running to the anterior genital mass ; its 

 diameter mostly 3'5 mm., anteriorly much thinner. The anterior 

 genital mass large, 3*5 cm. long by a height of 3 and a thickness of 

 1-5 ; chiefly formed by the large muco-albuminous gland. On the 

 right side of this appeared a black central region of oval form, 

 11 mm. long, encircled by alternately more whitish and more 

 yellowish arcuate windings ; the left side more simple with a 

 large winding. The curved sperm-oviduct extended 5 cm. long by 

 diameter of 8-4 mm. ; on the cuts two tubes, separated by an 

 incomplete septum, appear. The spermatotheca, situated immedi- 

 ately before the pericai"dium, globular, of a diameter of 15 mm. The 

 dark grayish 2)Gnis (praeputium) folded up extended 5 cm. long by 

 diameter of 7-4 mm. ; to its posterior end, which is yellowish, the 

 strong retractor is attached, to its anterior end the digitations of 

 the protractor. The inside with fine longitudinal folds and a thicker 

 one, all with a number of black points. From the bottom of 

 the cavity projects the flattened, blackish only at the point, else 

 yellowish, somewhat strained glans, extended 15 mm. long by a
