trawl from a depth of 30 fms. and from sandy bottom with stony 

 Polyzoa," it was very hardened; two others were taken in False 

 Bay from rocky bottom with many sponges. 



The length of the two largest was 3-35 cm. by a height of 0"8 ; 

 the height of the rhinophores 5 mm,, of the tentacles 2, of the 

 epinotidia 0*5-3; the back 1 cm. broad, the foot 1"2, the marginal 

 furrow continued along the side of the foot for 8-9 mm., the 

 length of the tail 4. 



The epinotidia in 2-4 series ; the inter-rhinophorial crest very 

 small ; the anus submedian, 2 mm. high. 



The bulhus pharyngeus 14-16 mm. long by a breadth of 9-9"5, and 

 a height of 1-1'b, the furrows of the posterior part of the mandibles 

 replaced by a thick edge (fig. 13) ; in general the forms of these 

 organs is rather variable in different specimens, the thickness of the 

 mandibles in front and in the middle of their length 3-5 and 4 mm. 

 The tongue 3 mm. high and long, the length of the rasp-sheath 

 4-5 mm. (its long nearly horizontal pulpy end 2 mm. long). In the 

 rasp about 18-20 rows of plates, and in the sheath 22-24 ; the 

 number of plates in the series could not be determined. The 

 plates as above.
