3Q2 APPENDIX* 



Having already ^iven a correct outline of this species, Vol. I. p. 

 Jig. 75., it will be unnecessary to describe its form. The lower jaw is 

 shortest, having ten or eleven punctures on the under part, and six 

 others on the upper jaw : gill-membrane 5-rayed. Body above fulvous 

 brown, the sides and belly silvery white ; the second dorsals and hind 

 part of the anal edged with a line of black ; caudal fin blackish ; a black 

 spot in the middle of the second dorsal; the upper half of the first dorsal 

 is also black. 



PHYSIS Siculus. (Vol. II. p. 301.^^. 95.) 



Cirrus on the nostrils^ small on the lower jaw^ con- 

 spicuous ; ventral fin only reaching as far the vent. 



Dorsal 8, 60 ; pectoral 15 ; ventral 2 ; anal 56 ; caudal 25- 



Inhabits Sicily. 



A correct outline of this second Sicilian species is given at page 306., 

 which will at once show how much it differs from the last. The longest di- 

 vision of the ventrals only reaches as far as the vent, and there is no black 

 upon the fins. The colour is a very dark and rich chocolate or rufous 

 brown ; the fins being nearly black, and the sides of the head and the dorsal 

 and anal tipt with white, and body having a yellow gloss. After the fish has 

 been dead some time, the colours fade, and the fins then appear edged with 

 black ; the anterior nostril has behind it a very short skin resembling a 

 cirrus. Total length generally about three-quarters of a foot. 



FEhlCUTRY ^ filamentosus. Sickle-finned Silui-e. 



Cirri four ; dorsal and pectoral fins with the spines 

 serrated, and surmounted by cartilaginous and articu- 

 lated filaments ; pectoral much larger than the ventral 

 fin, which has only six rays ; lower fins white. 



Dorsal 1-8 ; pectoral 1-14 ; ventral 6 ; anal 20 ; caudal about 20. 



Estuaries of rivers near Pernambuco, Brazil. 



Average length about two feet ; body thick, sub-cylindrical ; head sud- 

 denly descending, and flattened, bony, but covered with the common skin ; 

 muzzle broad and rounded ; mouth large, opening horizontally, and rather 

 beneath the upper jaw, which has, at each angle of the gape, a long com- 

 pressed sinewy cirrus, which extends as far as the termination of the first 

 dorsal fin ; lower jaw with another pair of cirri, not one-fourth the length 

 of the upper, round, fleshy, and placed beneath the tip of the jaw ; teeih 

 numerous, sharp, and very small, placed in two broad rows on the upper 

 jaw, and in one on the under ; tongue very large, thick, cartilaginous, and 

 rounded ; branchial membrane 5-rayed, the aperture small ; eyes small, 

 apparently covered with a skin ; pectoral fin close to the branchial opening 

 and to the belly ; the first ray composed of a strong compressed spine, 

 with barbed serratures on each side : to this is united, near the end, and on 

 the inner side, a compressed, hard, but pliable and articulated filament, 

 which is as long as the spine itself, and extends to beyond the vent ; the 

 other rays are not lengthened, but rapidly diminish. The first dorsal is
