 margin of the pronotum.

IX. ECHINODERMATA. 



By F. Jeffrey Bell.. 



(Plates VIII. & IX.) 



The collection of Echinodermata which Dr. Coppinger has for- 

 warded presents some points of considerable interest. Of the Echi- 

 noidea there is one species which is apparently new to science ; 

 the species Echimis mag ell amicus was found on the eastern side of 

 the coast of South America ; the Ophiurida are represented by four 

 species, of which two, one of them an Astrophytid, appear to be 

 new to science ; while the new species of Asterida seem to make it 

 necessary to direct attention to the fact that, if the number of new 

 species of Echinodermata appears to be disproportionately large as 

 compared with the MoUusca or Crustacea, it n)ust be borne in mind 

 that Dr. Cunningham's account of his collection, made in 18G9, ter- 

 minates with the latter of these groups, and that therefore our 

 knowledge of the Eehinoderm fauna of this region is in a less 

 advanced condition. The Holothuroida are feebly represented in 

 the present collection ; and no specimen of the Criuoida has been 

 as yet forwarded to the Museum.

A number of these interesting forms were forwarded by Dr. Cop- 

 pinger. As was natural, I examined them with eagerness in order
