3*5, the height of the gill 2-5 mm., the breadth of the foot 4, 

 the length of the tail 2 mm. The animal was of a uniform 

 whitish colour, the tubercles of the back white, the gill grayish. 



The form was longish oval ; the back covered all over with small 

 rounded tubercles of a diameter of about 0'25 mm. These were also 

 very distinct on the margin of the gill and of the rhinophore 

 cavities ; the gill seemed formed of about 12 simply pinnate leaves. 

 The tentacles appeared merely as small tubercles. 



The central nervous system, eyes and otocysts as usual. In 

 the skin of the back calcined cells and spicules were in abundance. 



The mouth tube 2-5 mm. long. The whitish bulbus pharyngeus 

 3 - 5 mm. long by a breadth and a height of 3, with rather prominent 

 rasp -sheath : the lip plates large, nearly joining above and below, 

 about 2 mm. high, 1 mm. broad, yellow ; their elements (fig. 25) 

 somewhat bent, 0*08 mm. high. The rasp yellow, with many series 

 of plates. The number of plates in the series could not be deter- 

 mined. The plates (fig. 26) nearly colourless, of a height up i>o 

 0-08 mm., the hooks finely denticulated. 



The salivary glands long, white, flattened. 



The stomach large, 3 mm. broad, covering the anterior half of the 

 liver. The posterior visceral mass (liver) yellowish white, short, 

 conical, 7 mm. long by a breadth of 3*5. 



This form is very likely identical with one of the many hitherto 

 described species of Chromodoris.

One specimen was sent for examination. It had been captured at 

 low tide on rocks at Kalk Bay. 



The length of the animal was 4*7 cm. by a breadth of 1*5 and a 

 height of 09 cm. ; the diameter of the gill aperture was 3 mm., the 

 height of the retracted gill 3 mm. ; the breadth of the brim of the 

 back 2*5 mm. ; the foot 8 mm. broad, its brim measured 2. — The back 

 was of a brown colour, the whole of the under side whitish, and on 

 the sides of the body were some scattered grayish brown spots (the 

 colour rubbed off?); the club of the rhinophores brownish, so, too, 

 the rhachides of the gill-leaves.
