center of disk are they as numerous as in granulosus, and as just 

 indicated they are not larger in the center of the plate (which is a 

 characteristic of granulosus.) Superomarginals 18. The first 7 plates 

 have a central group of coarse, hemispherical granules, which in a 

 dried specimen remind one of little heaps of stones. The first plate 

 has 24 granules and the seventh, 5 or 6. The first inferomarginals 

 are covered with coarse granules which decrease in size from the 

 edge of ray toward the inner margin of plate. 



ANTHENOIDES RUGULOSUS, new species. 



Differing from ^1. granulosus in having longer, slenderer rays, 

 narrower marginal plates, rather more numerous and smaller uniform 

 abactinal granules, a fine superomarginal granulation (except for a 

 few central coarse hemispherical granules on the proximal plates) 

 and more elevated, pincer-shaped abactinal pedicellarise. R=-124 

 mm., r = 47 mm., R = 2.6 + r; breadth of ray at first superomarginal, 

 52 mm. Disk large, rays distally narrow, tapering arcuately from 

 wide interbrachia; disk more or less inflated; whole body overlaid 

 by smooth, rather thick, soft skin, minutely wrinkled on the abactinal 

 area and covering a fine, close, uniform granulation; small forceps- 

 shaped, abactinal pedicellarise ; superomarginal plates smooth, the 

 membrane covering fine, spaced granules, and on the proximal plates 

 a few scattered coarse central granules; superomarginals of middle 

 region of ray in large specimens longer than wide; actinal inter- 

 radial areas variable, usually fairly smooth, the plates with central, 

 enlarged, hemispherical granules, as in granulosus; the plates adja- 

 cent to adambulacrals with a variable number of forcipiform or 

 spatulate, lower, pedicellarise; furrow spines compressed, usually 7 or 

 8 proximally, varying to 6 to 9, the armature in general similar to 

 that of A. granulosus; oral spines, 14 or 15.
