Boone, Mollusca, Cruises of "Ara" and "Alva" 343 



buccal membrance bears a continuous series in approximately six 

 rows of numerous closely-set, fleshy, soft-bodies, denticle-like, dis- 

 tally blunted papillae. The lower mandible is strong, sharp, closely 

 coordinated with the upper mandible. 



The sessile anus are short, in the sequence 4, 3, 2, 1, the in- 

 crease in length of the successive pairs being but very little ; like- 

 wise the depth of the umbrella or web is about the same between 

 pairs 1, 2 and 3. The pairs 3 and 4 are each longitudinally ribbed, 

 or carina-like on their respective upper second and lower third 

 lateral margins. The suckers are set obliquely, in four approxi- 

 mate longitudinal series and each furnished with a chitinous ring 

 which is devoid of teeth. 



The tentacular arms are withdrawn in the present specimen, 

 except for the distal portion of the left one, which bears numer- 

 ous small suckers, in six or seven series set across the somewhat 

 triangulate form of tentacle.
