Busk in his ' Challenger ' Report corrects his previous statement as regards 

 the shape o£ the oral opening ; and he figures the raised lines which are on 

 each side o£ the zooecium and extend throughout its length. The appearance 

 of the dead zoarium is striking from its almost black colour. 



I dredged this mingled with Crista ehurnea ; and in the Johnsonian 

 Collection it was freely covering a valve of Avicula tarentina.

It is true that Reuss's original figure could not be supposed by itself to 

 represent the species as observed by Busk, yet illustrated subsequently as it 

 has been by the figures of Stoliczka and Manzoni, the former of which have 

 been acknowledged by Reuss to represent his species, I have no hesitation 

 in regarding the species which I have dredged in about 70 fathoms at 

 Madeira, and of winch Senhor De Noronha has sent me a young specimen 

 taken from the telegraphic cable off Funchal, as referable to the fossil form. 

 At the suggestion of Dr. Levinsen I have placed the species in the genus 

 Adeonellopsis of Macgillivray, who has found several allied forms in the 

 Australian seas,
