markably, by the fact of its having been " dredged alive in 

 water from one hundred and ten to one hundred and 

 forty fathoms in depth, off" the Mull of Galloway." These

 inhabitant of deeper water than any other of the family, 

 not excluding Galaihea nexa. 



I have taken upon me, in restoring the genus to which 

 this species belongs, to change the specific name. The dis- 

 covery of a second species, as before mentioned, has ren- 

 dered this necessary, as the latter is far more rugous in 

 every part than the present species ; and I have ventured 

 to name it in honour of its first describer.
