162 ARAEOSTERNUS. 



called Palinurellus loienecki, is uudoubtetüy a distinct spe- 

 cies different from the American Palinurellus Gundlachi, 

 described by von Martens and afterwards by Pfeflfer, and 

 may , I believe , be distinguished from it by its larger size 

 and by the fifth pair of the ambulatory legs not being 

 provided with a rudimentary hand. 



I may finally be allowed to remark that the description 

 of P. Gundlachi^ given by Prof, von Martens, is rather 

 short and incomplete and that the learned Professor did 

 not publish a figure of that animal , and so I trust the 

 descriptions and figures given by myself, to which I have 

 above referred , may not be altogether superfluous.

P. S. After this note had been sent to the press, I 

 received the » Zoologischer Anzeiger" of March 6, 1882. 

 In this number Dr. J. E. V. Boas of Copenhagen shows 

 that Palinurellus has last year also been described by Spence 

 Bate under the new name of Sijnaxes in the » Annals and 

 Magazine of Natural History. 5th ser. , vol. VII (1881) 

 p. 220". In this paper Dr. Boas further adds some re- 

 marks concerning the affinities and the phylogeny of this 

 interesting genus of Crustaceans.
