1904. J FROM EAST AFRICA AND ZANZIBAR. 397 



15 mm., breadth 7, height 8. The mantle- edge is narrow except 

 over the head, where it is ample. The branchial opening is 

 minute ; the branchiae are small, 10 in number, and apparently set 

 in a perfect circle. The foot is rounded and grooved in fi-ont ; 

 the shape of the head is spatulate. The labial armature is a 

 yeUow ring of mace-like elements. The radula is small and 

 transparent, the formula being about 35.0.35 x 80. The ordinary 

 teeth are bifid, and all appear to have four denticles under the 

 top hook. The innermost have one or two denticles on the inner 

 side. The outermost are iri-egularly serrate {vide PI. XXIV. 

 fig. 7). No rhachidian thickenings are to be seen. 



Although the published plates of C7ir. Imeata and CAr. Mlaris 

 are remarkably different, the scheme of coloration is much the 

 same; and I think it probable that the two forms are really 

 varieties of one species. 



14. Chromodoris ?lixeata, var. nigrolineata. 



One specimen from Ohuaka on the East Coast of Zanzibar. 



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

 spatula-lil^e. Dorsal side whitish at edges, lemon-yellow medianly 

 with longitudinal black lines. Gills and rhinophores short, 

 orange-red. Underside colourless, but edge of foot and mantle 

 bright dark blue (not purple)." Size 18 mm. long, 6 mm. broad. 



The alcoholic specimen is of a waxy white. There are only 

 faint traces of the blue borders, but there are five distinct black 

 lines on the back, two of which are di^dded again so as to form 

 long loops. The mantle-edge is thick and narrow. It measures 

 about 2 mm. over the head and tail, but is hai-dly distinguishable 

 at the sides. The anterior end of the foot is rounded and gixioved. 

 The small branchiae are set in a circle and exposed. The buccal 

 mass is small. The labial armatvire is transparent, and consists 

 of rather irregulor short hooks, some cleft. The small ti-ans- 

 parent radula is as in Chr. Mlaris. 



15, Chromodoris ?magxifica Q. & G., var. 



One specimen from Zanzibar, dredged in 4 fathoms. 



The following are the notes on the living animal : — " 40 mm. 

 by 10 mm. Elongate in form, fore end spatula- shaped. Colour 

 white and rather translucent. Mantle with a thin yellow border, 

 within which was a band of deep but brilliant violet, broadest in 

 front and behind but broken latei-ally. There was also a violet 

 line along the sides of the foot, and six longitudinal lines of deep 

 chocolate- colour and difTerent lengths along the back. They were 

 surrounded by thin clear lines of opaque white. There was also 

 a line of chocolate blotches along the side of the foot just below 

 the shelf-like edges of the mantle. Branchiee 10, simply pinnate, 

 with a band of orange-red along each side of each plume. Rhino- 

 phores a deeper tint of orange. The tail pi'ojected well behind 

 the mantle and bore chocolate blotches." 



The alcoholic specimen is of a pale yellow, with the above-
