whole structure is as a whole en- 

 tirely like that of Archaster or Astro- 

 peden, as one can see from the 

 following characterisation. 



The arms are moderately long, 

 rather slender and pointed, arm 

 angles round, the great radius 

 36 mm, the small 11 mm, number of 

 the marginal plates 24-25. In the 

 middle of the arms the breadth of 

 the paxillar area is ecjual to that of 

 the marginal plates ; the area con- 

 sists there of many small paxillœ, 

 on the disk these become larger, 

 even moderately large, but again 

 small towards the centre of the disk. 

 The larger they are, the more dis- 

 tinctly one sees, that there are two 

 kinds of papilla?, those which are 

 shoi"t, closely packed, squarely trun- 

 cated, which clothe the top face of 

 the x^axilla, and those that are longer, 

 slenderer, horizontal and more cyhnd- 

 rical, which border its margin in the 

 form of a crown. The madreporic 

 plate I suppose to lie hidden by a 

 paxilla distinguished by its large size, 

 and situated about midway between 

 the centre of the disk and the 

 marginal platijs. These are tliickly 

 covered with flat granules perfectly 

 similar to those which clothe the top 

 smiace of the x^^^i^l^ l along the 

 grooves that separate the plates they 

 are replaced by longer, finer, hori- 

 zontal, bristle-like papill^e.^^ The

 plates and the imxilla; is thus so e\'ident in
