ELIOT : NUDIBEANCHIATA FEOM CAPE VEED ISLANDS. 



157 



The jaws bear a single row of large distinct denticles. The radula 

 is uniseriate, and consists of 22 teeth, which have a strong central 

 cusp and 4-5 long, distinct, clear-cut lateral denticles. The denticles 

 do not extend up the sides of the cusp. 



No spine or hook was found on the verge. 



This animal does not seem referable to any described species of 

 -Solid, and the long annulated cerata form a remarkable character 

 which will probably render its recognition easy. I refer it somewhat 

 doubtfully to Phidiana, though it does not seem to possess the 

 armature on the male genitalia which Bergh considers characteristic of 

 the genus.

Four specimens. Mr. Crossland's notes on the first two are as 

 follows : — 



" Solids, from the bottom of a big rowing boat. 



" The larger specimen rather less than 1 inch long ; proportionately 

 broad, but tapering posteriorly. Body translucent, cream colour, with 

 a few whitish opaque markings. Cerata rather small, of uniform 

 thickness, coloured drab brown by liver, but end sac is transparent and 

 colourless. The parts around the mouth, the penis (protruded in 

 several), and the anterior groove of the foot, are pink. At the neck 

 a crimson organ shows through. Two small black eyes. Rhinophores 

 bright orange at base, dying out to light yellow in the deeply 

 perfoliated part. Anterior tentacles long and mobile. The shorter 

 rhinophores stand stiff and upright some little distance behind. Foot 

 has a groove and notch, angles drawn out, but hardly tentacle-like. 

 Sides of foot form delicate membranes, tail long and slender. This 

 appears to be damaged more or less, or broken off in all but one 

 specimen. 



"Cerata arranged in groups on laterally placed swellings of 

 body- wall. 



" One specimen had five groups containing 11.9.8.6.6 cerata 

 respectively, but some were lost posteriorly, and in any case were 

 very small." 



Of the other two specimens he writes : — 



" Porto Praya. Under a stone with Polyzoa. Cerata very dark 

 drab brown, then dark red just below the whitish end sac. In one 

 specimen the liver is much redder than in the other." 



The preserved specimens correspond with these descriptions as far 

 as the characters are still recognizable, but are somewhat thicker and 

 stouter, doubtless owing to contraction, the largest being 8 mm. long 

 and 3-5 wide. The cerata are small and bent, the largest 2 mm. 

 long, the smaller minute. They are very caducous, and appear to be 

 set in curved lines on slight prominences. The rhinophores are thick, 

 with deep perfoliations ; the tentacles also thick and of moderate
