Very abundant in 50-70 fathoms oflF coast between the Lazaretto and Cabo 

 do Garajao on shells, Ditrupse, and coral {A. M. N.)\ Porto Santo, 60 fathoms 

 [De Noronha) . Jullien, Waters, and Hincks have figured the remarkable 

 large avicularia of this genus. 



Setosella vulnerata (Busk). B. 



In 70 fathoms, the same ground as the last, chiefly on Ditrupse and shell ; 

 whereas in the Shetland Sea I invariably found it on very small pebbles. 



Calpensia impressa (Moll).

I have not seen this species, but Dr. Levinsen informs me that he would 

 place it in the genus Onchoporella, Busk (' Challenger '). 



The Genera Catenicella, Catenaria, and Alysidium. 



1. Savigny never used the generic name Catenaria. Under Savigny's 



plate (Savigny's Egypte, pi. 13) we find the French word " Catenaires," 

 but in the description of the plate by Audouin the two species are 

 assigned to the genus Eucratea. 



2. Blainville, Man. d'Actinologie, 1834, p. 462, establishes the genus 



Catenicella in this curious fashion : " Nous avons trouve ce eenre, 

 indique par Savigny dans les planches du grande ouvrage sur 

 I'Egypte sous le nom de Catenaria, que nous avons modifie en celui 

 de Catenicella."" Here is given a name Catenaria which does not 

 really exist. There is a reference to Savigny's figures, parts of which 

 are reproduced, but he is unacquaioted with the description of the
