Fishes taken at Madeira. 283 



S. Crocodilus, Val., may be the same species, but the fin-formula 

 assigned to the latter (1st D. 20. A. 18) hardly admits of this 

 supposition. It is not impossible, however, that the fish shortly 

 described by Mr. Lowe, under the name of Scopelus maderensis 

 (Trans. Zool. Soc. iii. p. 14) may have been an example of S. 

 Bonapartii. The fin-rays were thus counted by him : 1st D. 13. 

 A. 14. C. 15. P. 13. V. 8; but he is silent as to the spines 

 on the tail, and the spine above the eye. ,

Elongate, compressed, of a brown cdh#P ; the scales minute, 

 cycloid. The height of the body compared with the total length 

 is as 1 to 10^. The head is large, being nearly one-fourth of 

 the total length. The large oval eye is distant two diameters 

 from the tip of the snout, and is contained about four times in 

 the head, which is channeled between the eyes, and has two ridges 

 converging forwards. It is unarmed, and the opercular pieces 

 are toothless. The opercle and the scapulary bones are concen- 

 trically striate. The lower jaw is rather longer than the upper, 

 and the mouth is slightly oblique. All the teeth are uniserial 

 and minute; those at the sides of the premaxillary, which 

 forms the upper border of the mouth, are alternately acute and 

 rounded, with a cutting edge. In the lower jaw there is a single 

 series of sharp, conical, curved teeth, larger at the sides than 

 those of the upper jaw ; and the palatines are armed with similar 

 teeth. The tongue is spoon-shaped, and its margin carries a few 

 small acute teeth. 



The short and moderately high first dorsal fin is placed behind
