The Opisthobranchiata of South Africa. 27 



2. Philine capensis, Bgh. n. sp. 

 PI. V., figs. 11-15. 



Off Cape Point Lighthouse, SW. by W. 4 \ miles, one specimen 

 was taken by shrimp-trawl from a depth of 29 fms. on bottom of 

 fine sand. 



It was of whitish-yellow colour. Its length was 11 by a breadth 

 of 7 and a height of 6 mm. ; the frontal shield very inclined 

 forwards, 6 mm. long ; the mantle shield 9 mm. long by a breadth 

 of 5 ; the wings of the foot 2-5 high. 



The thin mantle quite enveloping the shell except (by muti- 

 lation of?) the middle. The shell as long and large as the 

 mantle, chalk-white, not thin, but rather fragile, of usual (fig. 11) 

 form. 



The bulbus pharyngeus 1 mm. long, with prominent rasp-sheath, 

 the lip disk with strong cuticula. In the yellow rasp of the tongue 

 8 series of rows, in the sheath 14, the total number of rows being 

 therefore 22 ; the radula formula was 2-1-0-1-2. The nearly 

 colourless lateral plates (fig. 12) of about the usual form, (in direct 

 line) measuring in length 0*30 ; the first external plate rather thin, 

 about O20 mm. long (fig. 13) ; the other, the outermost, shorter and 

 a little thicker, 014 mm. high (fig. 14). 



The whitish salivary glands long, strong, very nodular. 



The masticatory stomach 3*5 mm. long by a diameter of 3 ; of its 

 plates, the median a little smaller than the others, which measured 

 25 mm. in length by a breadth of 1 (fig. 15) ; they were greenish 

 yellow, rather thin and flexible ; no holes could be detected either on 

 the outer or on the inner side. 



The large liver, sausage-formed, 7 mm. long, 4 broad, gray on the 

 outside, its substance brown-gray. 



The penis and the very large bundle of coils of the prostata 

 seemed to agree with the arrangement in the typical species. 



This form belongs to the group of Philine, which has outer as 

 well as lateral plates— one {Ph. scabra, M. ; Ph. catena, Mtg. ; 

 Ph. Loveni, Malm ; Ph. sinuata, Stimps), or two (Ph. quadrata, 

 Wood; Ph. lima, Brown; Ph. velutinoides, Sars), or several (6} 

 (Ph. pruinosa, Clark)."
