78 Marine Investigations in South Africa. Vol. V. 



left through the transverse and Hnk furrow of the hver, then for- 

 wards, forming a bend on the upper side of the anterior genital 

 mass, then runs backwards to the anal papilla ; the length of the 

 intestine 6 and 10 cm. by diameter of 7 and (3-) 5 mm. ; the 

 yellowish gray and blackish contents of the intestine were more or 

 less crumbled animal substances filled with spicules, perhaps of 

 Holothuriae. The posterior visceral mass (liver) on the surface 

 yellowish white, 3 and 3*5 cm. long by a breadth of 1-7 and 2-3 

 and a height of 1-3 and 2 cm. ; the mass was rounded behind and 

 before, the anterior half a little lower ; a transverse furrow divides 

 the mass on its upper side into two parts of nearly equal size ; it is 

 continued along the left side to the anterior end ; the substance of 

 the liver dirty yellow ; the cavity rather small. 



The pericardium large, 28 mm. broad by a length of 22 ; the 

 ventricle of the heart 11 mm. long by a breadth of 9. The blood 

 gland whitish, thin, of oval form, 17 mm. long by a breadth of 9, 

 lying to the right within the genuflection of the intestine. The 

 reno-2oericardial organ whitish, flattened, 4 mm. broad ; its duct 

 20 mm. long. 



The hermaphrodite gland nearly clothing the whole liver with a 

 whitish layer 2.-4 mm. thick ; in its lobules ripe sexual elements. 

 The anterior genital mass (in the larger individual) 2*8 cm. long by 

 a height of 2-2 and a breadth of 1-5 ; the efi^erent ducts moreover 

 projecting 1 cm. The hermaphroditic duct forming a longish bunch 

 of coils on the left side of the hindermost part of the genital mass. 

 The spermatotheca is a long grayish pyriform bag of the length of 

 2 cm. by a diameter of 1 ; the vaginal duct about 4 cm. long, the 

 vagina somewhat wider; the uterine duct 16 mm. long; somewhat 

 about its middle hangs the small pyriform spermatocyst of a length 

 of 4 mm., its duct about twice as long as the organ itself. The 

 muscular first part of the seminal duct short, passing into the white, 

 compressed prostatic part, that projects in a stronger, short con- 

 tinuation, ending in a strong, nearly globular ampulla of a length of 

 10 mm. by a diameter of 8 ; the continuation forwards nearly 2 cm. 

 long. In the last lies the glans penis ; its anterior end is somewhat 

 leaf-like, it is entirely covered with yellow pointed thorns (fig. 5) of a 

 length up to 012 mm. ; irregular forms are rather often seen. The 

 muco-albuminous gland very large, yellowish white and white. In 

 the vestibulum opens a brownish, rounded gland 7 mm. in diameter.* 



* The state of conservation of the anterior genital mass was not good. 



The condition of the vas deferens was as formerly represented by me (Cf. I.e., 

 taf. Ixxxiv. , figs. 46-47). 



The smaller individual showed the whole genital apparatus less developed ; on 

 the glans penis no armature could be detected.
