EOniXODERMATA. L23 



Strangely enough, De Blainville himself is not free from error in 

 the matter, for after Lesson's name he places the words " Voyage 

 de rUranie," a voyage with which Lesson had not the close relation 

 that he had with "that of the ' Coquille,' and in the account of which 

 no Echinoderms are described or figured.

Port Jackson. The two specimens are veiy different in appear- 

 ance : one has eleven arms, of which none are remarkably smaller 

 than the rest ; the other, which has five arms left, and appears to 

 have had six, has one arm much longer than the others, and has 

 three small subequal arms. 



* For the majority of the Asteroiclea I shall give only one reference, and 

 that to Perrier's 'Kevision des Stellerides' (Paris, 1875), following its pagination 

 as a separate work.
