the back on each side serrated ; a large black spot on the 

 first dorsal fin at the margin, extending between the third 

 and fifth rays. The whole body is rough : the spine on the 

 gill-covers extends nearly as far as the spine behind it ; the 

 lateral line and ridges on the back more strongly serrated 

 than on the Grey Gurnard." " Many of these," according to 

 Colonel Montagu, " are taken in the summer months on the 

 coast of Devon by the shore-nets ; their size inferior to the 

 other Gurnards, rarely exceeding a foot in length, and seldom 

 above nine or ten inches. 



The fin-ray formula, as given by Cuvier, is as follows : 



D. 8 19 : P. 11 3 : V. 1 + 5 : A. 17 : C. 11. 



This species occurs also in the Channel, at Boulogne, and, 

 as before mentioned, in the Mediterranean. Cuvier, and M. 

 Valenciennes, in their voluminous work now in progress, have 

 described the internal anatomical distinctions. 



Since the publication of the first edition of the British 

 Fishes, Dr. Parnell, in his published prize essay on the 

 Fishes of the Forth, and Mr. William Thompson, in his 

 notices of the Fishes of Ireland, published in the Annals of 

 Zoology and Botany, have considered this Gurnard as the 

 young only of the Grey Gurnard, and not therefore entitled 

 to specific distinction. Their reasons for coming to this 

 conclusion are also fully stated. It will be remembered that 

 this Gurnard has been figured as distinct by Klein, Bloch, 

 and Pennant ; and has been described as distinct by Risso, 

 and several others. In the first part of a very recent pub- 

 lication on the Fishes of Denmark, by M. Henry Kroyer, 

 a distinguished Danish naturalist lately returned from Spits- 

 bergen, and now travelling in Lapland, our Trigla Blochii 

 is included as distinct from T. gurnardus. Baron Cuvier 

 was perfectly aware of the changes which occur in the Grey 

 Gurnard. T. gurnardus, from youth to age, and the follow-
