Description. — Rays 5, R^50 mm., r==10 mm., R=5 r. Rays short, 

 heavy, and bluntly pointed, more or less cylindrical and tapering slightly 

 toward the tips. Height of ray at base 9.5 mm., at ray tip 6 mm. Width 

 of ray at base 11 mm., midray 10 mm., ray tip 8 mm. Skeleton composed 

 of numerous, irregular, swollen, compacted, granulated plates. The disk 

 is covered with large and small, irregular plates; the larger plates are ar- 

 ranged in an irregular circle within the .ray bases. Within the circle and 

 surrounding the anal opening are about 27 irregularly shaped plates of 

 various sizes. The plates are compactly covered with coarse, mosaiclike 

 granulations, which are round or rectangular. The granules surrounding 

 the anal aperture are heavier and longer. 



The broad abactinal surface of the ray is covered with large and com- 

 pact plates of irregular shapes and sizes, between which are often wedged 

 smaller, irregular plates. Transversely there are about 5 plates across the 

 arm, irregularly placed and overlapping without a definite serial arrange- 

 ment. On the sides of the rays are 2 regular series of papular areas of 

 about 20 pores each. The upper series, immediately above the supero- 

 marginal plates, averages 17 areas and extends to within 8 mm. of the 

 ray tip. The lower or intermarginal series averages 22 areas and extends 

 to the tip of the ray. The papular areas, which are separated one from 

 another by a single transversely oriented plate, are reinforced by a reticu- 

 lation of tiny ossicles which serves to separate the papulae and support 

 the granules.
