The Opisthohranchiata of South Africa. 85 



At a later date two specimens were procured off Constable Hill 

 (NNE. 6|- miles) by large trawl from green mud and a depth 

 of 33 fms. The living animal showed the " back of light 

 flesh colour." One specimen was small, only 2-3 cm. long, but 

 otherwise in respect to the frontal veil, the gills and even the everted 

 glans penis entirely agreeing with the larger, which was more 

 closely examined. 



This last was 4-5 cm. long by a breadth of 1-8 and a height, with 

 the gills, of 1-1 ; the breadth of the frontal veil 11 mm., the height 

 of the sheath of the rhinophores 2 and of the club 3 mm., the height 

 of the gills reaching up to 6 mm. ; the breadth of the foot 14 mm. 



The series of gills commenced with a small one, then followed 

 12-13 larger and finally came 5 small. The frontal veil on each 

 side with 4 small fingers. The back quite even. The pointed 

 conical glans penis projected straight out 5 mm. 



The biclbus i:)haryngeus 13 mm. long by a height of 7 and a breadth 

 of 8 ; the mandibles quite as above, the masticatory edge with some 

 few (3-5) smaller and about 5 stronger series of flattened denticles. 

 The cavity of the mouth colourless. The colourless rasp of the 

 tongue seemed to contain 23 series of plates ; the number of the 

 lateral plates could not be determined. The plates as above ; 

 the breadth of the median 0*35 mm. 



2. Teitonia indecora, Bgh. n. sp. 

 PI. XIII., fig. 16 ; PI. XIV., figs. 2-3. 



Two individuals were procured off Cape Point by a shrimp-crawl. 

 They were rather hardened and in a fair state of preservation ; the 

 largest was, as far as possible, examined anatomically. 



The specimens had a length of 30-35 mm. The breadth of the 

 back was in the largest 11 and the height also 11. 



The colour was whitish all over. When alive, they were of a 

 " pinkish colour." 



The form was as usual; the narrow frontal veil with a slight 

 median emargination, each side of which was provided with 11-12 

 pointed finger-like processes, the outermost slightly spoon-shaped. 

 The rhinophores seemed of the usual kind ; their sheath somewhat 

 crenulated with a stronger outer lobe. The back quite even, the 

 margin slightly projecting, rising (in the two individuals) on each 

 side in 5-8 rather low arborescences (of a height up to about 3 mm.) ; 

 between these here and there were some much smaller ones. The 

 foot as above. 



The intestines nowhere shining through.
