 S. a)i(/uk((a of Loven is a large form of this species. The 

 animal not having been suliicicntly described, I subjoin an 

 extract from my notes : — 



Body milk-white, with a tinge of yellowish brown in 

 front : Iiead thick, snout-shaped : tentacles conical, ciliated : 

 eijes small, one at the outer base of each tentacle : foot 

 tlouble-edged and bilobate in front, abruptly pointed behind; 

 its tail or extremity is pinched up and gro<Jved underneath : 

 opjjendages or pedal iilaments as in TrocJitts^ but more nu- 

 merous (eight on each side) ; these are angulated and finely 

 ciliated ; a white eye-spot is at the base of each filament. 

 The slit in the shell serves for excretal puqioses ; the fajces 

 are worm-shaped, long, and are visible through the shell. 

 The animal is shy and delicate, dying soon after being put 

 in a phial of sea-water.
