MELOCRINUS. 201 



Interradials, first row, five, lying between the radials and first primibrachs ; 

 second row, ten, lying between the first and second primibrachs ; third row, ten, 

 level with first row of secundibrachs ; fourth row, ten, level with second row of 

 secundibrachs. Plates all approximately hexagonal, regularly decreasing in size 

 upwards, deeply convex or bluntly pyramidal in their centres, which are con- 

 nected by steep prominent radiations. 



Size of imperfect calyx, 22 mm. by 25 mm. 



Locality. — A single specimen was found by Mr. J. G. Grenfell on the shore at 

 Torquay, in red crystalline limestone. 



Remarks. — This interesting specimen belongs to a part of the Devonian series 

 different from the Lummaton beds ; but having, by the kindness of Mr. Grenfell, 

 the opportunity of figuring it, I have introduced it here. Its true shape is lost 

 as it is obliquely crushed, and only part of its surface is seen, so that its descrip- 

 tion is in some degree tentative. After a very careful examination of it, however, 

 I think that the above interpretation is in all probability correct, judging from 

 the two radial and two interradial areas that can be observed. If this be so the 

 resemblance to F. Romer's species, in shape, in the arrangement of plates, and in 

 the style of ornament, is so great that it most probably belongs to that species ; 

 the only perplexirig point being that the upper rows of interradials seem to be two 

 instead of three in each area. The surface is a good deal injured, but the ornamen- 

 tation appears to be of the nature which Schultze describes as characteristic 

 of this species.
