round the mantle. The foot is of a hght violet-bkie ; the brancliiie 

 ofange with deep violet tips ; the rhinophores uniform deep violet. 

 The animals are sluggish and not very sensitive to touch. 



The buccal parts and other characters are as described by Bergh. 

 One specimen has six branchiae, the other eight, of which one was 

 posterior to the others and very small.

 [S. R. xvii. pp. 935-937.] 



Nine specimens fi"om Tundaua, Pemba, found on a sandy shore. 



The description of the living animals is as follows : — " Creamy 

 white. Foot and mantle edged with violet. On the back foiu' 

 undefined bi-own lines with three violet lines between. Foot 

 pi'ojects behind mantle. Gills and rhinophores vermilion. About 

 Ig inches long." 



The preserved specimens are longish and not very stovitly built. 

 The measurements of the largest are : length 25 mm., breadth 

 10 mm., and height 9 mm. The colour is the ordinary alcoholic 

 yellow ; on the back are ti-aces of foui- brownish and three white 

 lines, the latter representing the violet of the living animal. Some, 

 but not all, of the specimens appear to have a similar white line 

 on the sides of the body between the mantle and the foot. The 

 branchial aperture is very small ; the branchi?e themselves not 

 very small and 10-12 in number. The foot is i-ounded in front 

 and slightly grooved. The tentacles are distinct. The mantle- 

 edge is of ver}^ varying shape, sometimes fairly wide and thin, 

 sometimes merely a thick ridge. 



The labial armature and radula are much as represented in 

 Bergh's plates. The former is a grey ring composed of mace-like 

 elements. The latter is small and transparent. Most of the 

 teeth are bifid, with four oi- five accessory denticles below the two 

 jn-ongs. The innermost have one or two denticles on the inner 

 side. The rhachidian thickenings are small and not very 

 distinct. 



Bergh's specimen was in life " hell ocker-gelb " Avithfour bluish- 

 black lines on the back, but on the whole the colour and markings 

 are sufiiciently similar to justify us in regarding the present 

 specimens as merely varieties. 



13. Chromodoris lixeata Soul. (^ = Chr. hilaris B.) (Plate 



:s.x:iY. fig. 7.) 



One specimen from the East Coast of Zanziluir. 



The notes on the living animal are as follows : — " Cream- 

 coloured. Gills and i-hinophores vermilion. Thei-e were bright 

 violet lines on the cream-yellow ground, bordering the foot and 

 mantle : two along the sides of the body and five along the back. 

 The two outside ones encircled the rhinophore-pits and joined in 

 front ; the median encircled the gill-pocket." 



The alcoholic specimen is yellow and the violet lines have 

 become white. It is high and stout, the dimensions being — length
