BLOCK'S GURNARD. 51 



Bloch also, plate 59, considered this fish as the T. cuculus 

 of Linnaeus : Klein, however, appears to have been of a 

 different opinion ; and Cuvier and M. Valenciennes have 

 given it as a distinct species. Risso has also described it 

 as a distinct species, among his Fishes of the Mediterranean, 

 under the name of granaou, T. cuculus^ and says the first 

 spinous ray of the first dorsal fin is the longest ; which is 

 not the case in the common T. cuculus. Compared with 

 the common cuculus, (the true T. cuculus of Linnaeus, 

 the first of the Gurnards described and figured in the pre- 

 sent work,) Bloch's Gurnard will be found to have the 

 body longer and narrower, the head smaller but more pow- 

 erfully armed, the pectoral fins short, not reaching to the 

 anal fin, and the first dorsal fin having a conspicuous black 

 spot on the margin of the membrane connecting the fourth, 

 fifth, and sixth rays. The spot on the first dorsal fin, 

 however, must not be considered as sufficient alone to 

 identify this species ; as two specimens under comparison, 

 both having this black spot, are in reality only varieties 

 of the Grey Gurnard. 



Montagu considered the Red Gurnard, described in the 

 Memoirs of the Weraerian Society already quoted, as dis- 

 tinct from the Grey Gurnard ; but has certainly described 

 the common Red Gurnard under the term lineata, consi- 

 dering this word as applicable to the linear elevations along 

 the side which cross the lateral line, and which induced Bloch 

 to call the species T. pint. This character is shown in 

 the woodcut of the Red Gurnard, but is scarcely perceptible, 

 from its diminished size, without the assistance of a lens. 



Not possessing a specimen, the description of Colonel 

 Montagu is adopted. " The forehead is more sloping than 

 that of the Grey Gurnard ; the nose armed with three spines 

 on each side ; the spine on the operculum of the gills, and
