was caught on the north coast of Britain, and was commu- 

 nicated to him by Mr. Stuchbury. 



Dr. Fleming, in his History of British Animals, quotes 

 as a synonyme to radiata the R. Fullonica of the Fauna of 

 Greenland, by Fabricius ; and it is probably a Northern 

 species, the only three examples of it I have seen having 

 been received, one from Berwick Bay, and two from the 

 Frith of Forth. The first was a female, for which I am 

 indebted to the kindness of Dr, George Johnston, and from 

 this example the figure here given was derived. In 1835, 

 Dr. Parnell sent me from Edinburgh two examples, a male 

 and a female, which had been obtained in the Forth, and 

 obligingly permitted me to retain the male for my own col- 

 lection, which came marked accordingly. On comparing 

 these three examples with Mr. Donovan's figure, no doubt 

 remained that they were of the same species. 



The habits of this fish are but little known, and the figure 

 here given being that of a female, I shall closely describe 

 the male, which was nineteen inches long from the point of 

 the nose to the end of the tail, and fourteen inches in 

 breadth ; the snout but little produced, almost falling in 

 with the line of the anterior margin ; the lateral expansion 

 of the pectorals and their posterior margins rounded ; the 

 pelvic fins rather large : the central ridge of the nose, and a 

 great portion of the pectoral fins or wings, are covered with 

 asperities of different sizes, but the form of which are all 

 alike, being a single spine bent backwards, arising from a 

 stellated base of many radii ; these appear to be nearly sym- 

 metrical, and about equal in number on the two sides : the 

 eyes are blue and rather large, placed about half-way be- 

 tween the central transverse cartilaginous arch of the body 

 and the end of the snout ; before each eye one large spine, 

 and two large spines behind, with several smaller ones along
