116 Dr. J. E. Gray on Echinoderms collected by 



par Miiller on leur trouve plusieurs fois des ressemblances 

 avec 1' OpMura fragilis et 1' Ophiura tricolor de M. de Lamarck, 

 mais il seroit difficile de donner une determination positive " 

 (p. 206). 



Now that specimens have been obtained from the Red Sea 

 and the coast of Syria, it is found that many of the species 

 represented by Savigny are different from those to which Au- 

 douin referred them ; but as yet I have nut been able to com- 

 pare the species of that family with the published work on 

 them as carefully as I could have wished; and it is better 

 they should remain until Dr. Perceval Wright, who has 

 undertaken to make an examination of the Echinoderms in 

 the Museum, with some other naturalists who have paid special 

 attention to this group of animals, have examined and com- 

 pared them. 



I here give a list of the plates and the explanations as far 

 as they are referred to: —

I have made a list of all the species which I liave found 

 recorded as inhabiting the Red Sea, and marked those that 

 have been collected by Mr. M'Andrew, and those that are in 

 the British Museum from other sources. 



I have added a few notes formed on the examination of 

 Mr. M' Andrew's specimens.
