NUDIBEANCHS FEOM THE COAST OF NATAL. 225 



visible in the mantle margin, but they are situated inside the 

 integuments, and project only slightly or not at all. 



The labial armature is large and forms a nearly complete 

 circle. It is composed of large well-made bifid hooks. The 

 radula consists of fifty-five rows containing* forty to forty-five 

 teeth on either side of the rhachis, which bears triangular 

 thickenings. The teeth are tall and erect and bear six to eight 

 strong denticles. The innermost teeth have also at least three 

 denticles on the inner side. 



This appears to be Bergh's Chr. porcata from Mauri- 

 tius. The coloration is the same in essentials and the 

 buccal parts and mantle margin agree with his description. 



Chromodoris carnt^t Bergh. 



Chr. came a Bergh, " Mai. Unters." in ' Semper's Eeisen/ 

 Heft xvi, 2, pp. 836-7, Pi. LXXXIII, figs. 20-29. 



The notes on the living animal are as follows : '^ 14 x 2i 

 mm. Dorsal surface whitish with a few interrupted pure 

 white longitudinal lines; tentacles (i.e. rhinophores) whitish 

 with orange thread-like revolving line ; head, point of tail, 

 and branchias whitish, ornamented Avith branched orange 

 lines : mantle bordered with an occasionally interrupted band 

 of plum colour, turning white at extreme edges ; dorsal 

 surface sparsely and irregularly spotted with crimson and 

 orange ; under surface white." 



In the preserved specimen the mantle is narrow at the sides 

 but expanded over the head. The foot is expanded in front. 

 The labial armature is greyish -yellow and much as described 

 by Bergh. The elements are mace-like in shape. The radula 

 is also as described by Bergh. The formula is about 

 50 X 30 . . 30. The majority of the teeth are bifid with 

 four to five small denticles under the bifurcation. 



This appears to be a pale variety of Bergh's Chr. carnea 

 recorded from Mauritius.
