The bulbus pharyngeus, the oesophagus, and the gl. ptyalina 

 as in other Doriopsides. The Hver short-conical, truncate in front, 

 the length 7 mm., the colour yellowish gray ; scarcely any fissure of 

 the hinder end could be seen. 



The everted part of the vas deferens (fig. 5) 0'14 mm. broad, 

 showing 10-12 irregular quincunx series of thorns ; these last a 

 little bent, clear, colourless, mostly 0"02 mm. high (fig. 6).

DORIOPSILLA CAPENSIS, B. n. Sp. 



PI. VIIL, fig. 7. 



Along with Doris perplexa a specimen of this form was procured 

 by large trawl at Cape St. Blaize. 



The rather stiff specimen measured 15 mm. in length by a breadth 

 of 10 and a height of 7 ; the breadth of the nearly straight brim of 

 the back was 2 mm., that of the foot 9. It was uniformly coloured 

 whitish, the nodules of the back white. 



The form as usual ; the back covered all over with small rounded 

 nodules ; the gill situated far behind, formed of six leaves of the 

 height of 2 mm. 



The central nervous system as usual, the buccal ganglia seemed 

 to be situated in its immediate neighbourhood. The eyes were 

 somewhat flattened, of a diameter of about 0-25 mm. The back 

 filled full of calcified cells, groups of cells, and spicules proper (of a 

 diameter up to 0-06 mm.). 



The gl. ptyalina white, flattened, 3 mm. broad. The very thin 

 hulhus pilar ymjeus nearly 4 mm. long, the gl. salivales as usual, 

 the oesophagus very short. 



The large intestinal mass (liver) 10 mm. long by a breadth of 6 ; 

 the length of the cleft in the hinder end 1-75 mm. The dirty-yellow 

 liver on its sides for a breadth of 3 mm. covered by the transverse, 

 yellowish white bands of the hermaphrodite gland, in its lobes ripe 

 genital elements. The anterior genital mass meniscus-shaped, 

 6 mm. long, whitish, and dirty yellowish. The penis as usual, the 

 diameter of the glans (fig. 7) at its point 0-10 mm. ; the hooks small, 

 reaching a height of 0-013 mm. 



At South Head (E. by S. ^ S., 25 miles) nine individuals of 

 probably the same animal were caught by shrimp-trawl from a depth 

 of 190 fms. with a bottom of green sand and black specks.
