The height of the body is less than one-fourth of the total 

 length. A black spot on the back of the tail, at the base of the 

 caudal fin. 



Coast of Cornwall. 



Only one specimen, from which Mr. Couch has given his descrip- 

 tion, has occurred, and it was not preserved. All the other accounts 

 of the fish are reproductions of Mr. Couch's original description. Con- 

 sidering the frequent cases of variation in the number of the spines 

 of the genera Labrus and Acantholabrus, we cannot help thinking 

 that the specimen observed was an individual variety.
