however, two little liine nodules bedded in the skin of that region, over each 

 joint. Disk large and flat, covered by a thick, somewhat wrinkled akin, 

 densely beset above and below by short spines, whose bases are enclosed in a 

 sheath of skin, beyond which projects a sharp, translucent point, or a fork. 

 The arm-spines are represented by a row of seven or eight minute compound 

 booklets, about 1 mm. long. They are translucent and end in a sharp hook, 

 and have two or three curved spurs on the same side. At the very tip of the 

 arm the structure does not vary, except that the booklets with their knob-like 

 bases are reduced to two. The large smooth tentacles have no special scales. 

 Color in alcohol, disk light yellowish brown; arms paler.
