122 Dr. J. E. Gray on Echinoderms collected hy 



A. Blainvillei^ but small and pointed, and the corona covered 

 with true spines. 



Agassiz notices a small specimen from the Red Sea in the 

 Paris Museum, which he names A. Blainvillei. 



See Dujardin & Hup^, Ecliin. p. 540. 



I believe, from Mr, M' Andrew's scries, that the A. Blain- 

 villei is only a variety of A. mamillata.
