The Opisthobranchiata of South Africa. 55 



series, and often several times in the same series (fig. 13) ; the 

 point of the plates sometimes bifid. 



The white salivary glands were long and thin. 



The oesophagus 1*2 cm. long. The (liver-) stomachal cavity 

 rather small ; the intestine appearing at about the middle of the 

 length of the liver, turning on the anterior genital mass and 

 going backwards to the anal papilla. The length of the intestine 

 2*5 cm. by a diameter generally of 3 mm. The liver clear yellowish 

 gray, rather short and thick, 12 mm. long by a diameter of 9, with a 

 depression for the anterior genital mass. 



The reno-pericardial organ rather roundish, of a diameter of 

 1*5 mm. 



The anterior genital mass seemed of a rather complicated nature, 

 but it could not be made out in the hardened specimen ; it was 

 about 15 mm. long by a diameter of 7-8. Its hinder part was 

 formed by a sort of short pyramid, yellowish gray, of a height 

 of 6 mm., by a base of 8, very likely opening in the vestibulum ; the 

 rest of the mass whitish and yellowish ; the sperm atotheca globular, 

 of a diameter of 3 '5; the coil of the windings of the vas deferens 

 very large, consisting of a longer prostatic and a shorter muscular 

 part ; the penis 6 mm. long, without armature. 



This form cannot apparently be placed in any of the hitherto 

 known genera of Dorididae ; it agrees with the Chromodoris and the 

 Halla in the simply pinnate nature of the gill-leaves.

Off Sebastian Bluff (W. by N., f N., 7 miles) one individual was 

 taken by large dredge from a depth of 20 fms. ; the bottom was coral 

 and stones. 



The animal was 15 mm. long by a breadth of 6 and a height
