Localities. — Zanzibar, 1901, shallow water, low tide; five

The Body is long, subconical, bluntly pointed behind ; the fin 

 extends the full length of the body ; it is suboval, broadest just 

 behind the middle. 



The Head is short and nearly equal in breadth to the body ; the 

 eyes are large, with a minute pore like a pin-prick just in front 

 of each ; the auditory crest has a sigmoid curve and a similar pore 

 in the concavity of the lower half. The buccal membrane is 

 attached by seven ligaments (the dorsal one bifurcating) to the 

 eight arms ; each point of the membrane bears near its tip five or 

 six suclcers, of which the horny ring bears in its two distal thirds 

 twelve stout blunt teeth, whilst the proximal third has nine much 

 smaller rounded denticles (text-fig. 132).

 with a well-developed protective membrane on either side of the

 extends from the membrane connectine' it with the third arm
