240 JOUKNAL OF CONCHOI.OGY, VOL. II, NO. 8, OCTOBER, I905. 



here and there. They are numerous, very thin, rather large and 

 foliaceous. The rhinophores are close together, violet with yellow 

 tips. They bear vertical lamellcC. The mantle edge is continuous 

 behind them and deeply indented. No caruncle is visible. The 

 tentacular shield is pale violet grey with ample auriculate ends. 



The jaws bear at least eight rows of denticles, behind which are 

 smaller projections resembling a tessellated pavement. 



The radula consists of 45 rows with a formula of about 55.1. 1. 1.55. 

 The median tooth has a strong central cusp with one denticle on each 

 side rather high up, and five lower down. The first lateral bears 5-6 

 denticles on the external side, and the next few laterals 4-5, After 

 that the number does not exceed three, and towards the end of the 

 row is two or one only. The last 10-12 teeth are quite smooth. The 

 teeth have slender projections behind the bases, as in Bergh's figure 

 (Joe. cit., plate vi., fig. 5). 



In spite of some slight differences of colour, I think this specimen 

 may be referred to F. taeniolata, recorded hitherto only from Mozam- 

 bique.

One specimen from Charbar captured in ten fathoms. According 

 to the notes, the animal, which varied its shape continually, was drab- 

 grey, turning to slate-grey, with white spots surrounded by a margin 

 of the same colour as the dorsal surface, but darker. The under 

 surface was " pellucid like a jelly fish." The buccal mass was 

 protruded (apparently during life) and pinkish. 



The preserved specimen is nearly circular, being 15 mm. long and 

 14 mm. broad. The mantle margin is unusually broad, measuring 

 8 mm. The back is brownish grey, bearing flat white tubercular spots 

 with dark-grey centres. A few larger ones are set in approximately 

 regular rows and are about i"5 mm. wide. The rest are about half that 

 size. The tentacular shield is covered with small white tubercles and the 

 anterior part of the body is arranged in the manner characteristic of 

 the genus. The foot and tentacular shield are bordered with white. 

 The gills are set on the under side of the broad mantle edge, but no 

 cleft is visible. They are twenty-five to thirty in number, and, as a 

 rule, each large one is followed by two small ones. The side lamellae 

 are not very numerous, being only about twenty. They are set slant- 

 wise and not parallel to the sides of the body. 



The buccal mass is very large and of a bright orange colour. The 

 jaws hear aL least six series of distinct denticles and smaller 

 prominences behind them, resembling a tessellated pa\ement. 'l"he
