JiVTANESE ASTEROIDEA.

My specimen No. 5 is so notably different from all the others 

 and like C. schmideliana in some points that it will be described 

 in detail. Its dimensions are driven below : 



As may be seen from the table, this specimen is very ir- 

 regular in shape, evidently owing to distortion (PI. XVII, fig. 201, 

 262). The flatness of the body is also characteristic, the height 

 being only 25-30 mm. for the greater part of the body. The 

 actinal side is very nearly plane, and the dorsal is slightly convex. 

 The apex of one of the ambulacral farrows has evidently been 

 injured and is regenerating in an abnormal way (left side of fig. 

 261). The outUne of the body is pentangular, the side being 

 almost straight except where they have evidently undergone dis- 

 tortion. The poriferous areas are generally rounded in outline 

 and of various sizes ; they appear to have a rather strong ten- 

 dency to coalesce with the neighbouring ones, and in many 

 places their arrangement in rosette-like groups is very distinct. 

 The poriferous areas extend to the outer borders of the actinal 

 side, and they mostly bear each a few (I— 3) coarse mammiform 

 granules Avhicli are smaller than those of the non-poriferous areas.
