Figs. 20, 21. 



Diameter of disc 7% mm. Length of arm about 7 times 

 diameter of disc. Disc covered above by large imbricated scales 

 and naked radial shields that meet along outer third. Inter- 

 brachial space granulated. Three pairs of mouth papillae, outer 

 one very broad, next narrower and inner one small and partly 

 mfradental. Mouth shield quadrangular, corners rounded, inner 

 angle most acute. Side mouth shields, broad, meeting within, 

 sub-triangular, corners rounded. Genital openings beginning at 

 mouth shield. Two flat tentacle scales, the distal one larger. 

 Ventral arm plates quadrangular, distal corners rounded, broader 

 than long. There is a minute plate separating the outer ends of 

 the side mouth shields that may be a vestige of the first ventral 

 arm plate. Dorsal arm plates ellipsoidal, about twice as broad 

 as long. Three stout sub-equal arm spines about the length of 

 an arm joint. Color of preserved specimen grey.
