Hah. Living in the Mediterranean, and fossil, in the Tertiary

The single specimen of Dr. Philippi afforded him material for 

 some anatomical notes upon the animal. Either there is a very 

 great difi'erence between this and the Pacific species, or the 

 paucity of material led him into error. He has apparently taken 

 the renal organ for a gill, and, in this manner, led later authors 

 into tlie error of placing Gadinia among the Cervicobranchiata.

This is not the type of the genus, nor was it described by 

 Gray, as Woodward states. It is the first of three species of 

 Gadinia described under the name of Mouretia by Sowerby, P. 

 Z. S. 1835.
