Near Table Bay (Lion's Head bearing N. 63 E., 34 miles) four 

 individuals were taken by shrimp-trawl from a depth of 154 fms. 

 on a bottom with black specks. The three individuals sent were 

 very hardened. 



Two were 15 and 23 mm. long. The third, which was dissected, 

 had a length of 33 by a breadth of 20 and a height of 14 mm., the 

 rhinophores 1 mm. high ; the brim of the back 5 mm. broad ; the 

 i-ound gill-hole of a diameter of 3 mm., the height of the retracted 

 gill-leaves 3 mm. ; the tentacles 1 mm. long, the breadth of the foot 

 6, the length of the tail 2 mm. The animal was uniformly coloured 

 whitish ; a fine white line along the margin of the back. 



The form longish-oval, the brim of the quite smooth back not 

 narrow, overlapping the head and the tail, the rhinophores per- 

 foliate ; the gill formed of 6 tripinnate leaves, the subcentral anal 

 papilla 3 mm. high. The tentacles short, finger-shaped ; the brim 

 of the foot rather narrow. 



Calcified groups of cells and spicules seldom occurred in the skin. 

 The bulbus pharyngeus 7 mm. long by a height and a breadth of 5, 

 the rasp-sheath not prominent, the lip disc clothed with a thick 

 white cuticle. The rasp of the tomjue yellowish, containing 9 series 

 of plates, in the rasp -sheath about 15, the total number of rows thus 

 being 24 ; the rows seemed to have about 25 plates on each side of 

 the very narrow rhachis. The plates nearly colourless, the height 

 of the 4 outermost was 006-012-0-14-0-16, rising to 037 mm. 

 The plates of the usual hook form (fig. 7), with hook quite even, the 

 outermost small (fig. 8). 



The white salivary glands long, their last two-thirds flattened, 

 1 mm. broad, the remaining hinder part very thin, the efferent 

 duct not short. 



The large stomach very prominent, 8 mm. long by a breadth of 

 G ; its contents were animal matter with quantities of pointed hard 

 spicules. The intestine 2-8 cm. long by a diameter of 0-5-1 mm. 

 The yellowish white liver short, conical, 14 mm. long with a hollow 

 base (for the stomach), of 11 mm. diameter. The gall-bladder 

 4-5 mm. higli by a diameter at its summit of 3-5.
