88 Marine Investigations in South Africa. Vol. V. 



narrow and the hinder end more pointed (fig. 9) ; the masticatory 

 edge about 0-14 mm. high, showing about 5-6 series of cones, whose 

 point projected about 0-025 mm. (fig. 10). The tongue as usual, 

 strong, the rasp nearly colourless, tapering anteriorly, containing 

 31 series of plates, in the sheath moreover 34, of which the three 

 hindermost were not quite developed, the total number of series 

 being thus 65. The number of lateral plates on each side of the 

 median seemed to rise to 75. The median plates bright yellow, the 

 lateral colourless ; the breadth of the median 0-16 mm., the height of 

 the lateral up to 0-16, that of the outermost 0*12. The median 

 plates of the form common in the Tritoniidae, but rather broad, with 

 a clumsy short median hook and two similar a little smaller (fig. 11). 

 The first lateral plate also typical, different from the rest (fig. 11) ; 

 these were of the common hook form, but slender (fig. 12), the 

 innermost more clumsy (fig. 11). 



The whitish salivary glands as usual. 



The oesophagus short, about 3 mm. long. The stomach partly 

 lying on the left side of the liver, somewhat constricted in the 

 middle, 9 mm. long by a breadth up to 4"5, empty ; the longitudinal 

 folds of the anterior part much stronger than those of the posterior. 

 The intestine issuing from the stomach near its end, ending near the 

 end of the liver. 



The liver brownish yellow, conical, 11 mm. long by a breadth in 

 front of 5 ; the anterior part was partly isolated from the rest by a 

 deep cleft entering from the right side and a smaller one interpolated 

 between the pylorus and the intestine. 



The large lobes of the yellowish white hermaphrodite gland were 

 spread over the upper side of the liver, and contained ripe genital 

 elements. The rather thick yellowish coils of the hermaphrodite 

 duct lay on the inside of the anterior genital mass. This last some- 

 what pear-shaped, 7 mm. long, white. The seminal vesicle globular, 

 of a diameter of 2 mm. ; the vaginal duct 2 cm. long. The prceputium 

 penis thin, reverted; the glans very long (3 cm.), its greater part 

 (2-5 cm.) freely projecting, cylindrical, with pointed end (fig. 13) ; 

 the seminal duct opened at its end.
