150 PISCES. 



LiCHIA, Cuv. 



The free spines on the back, and two others, also free, before the 

 anal; body compressed, and the tail without the lateral carinse. In 

 front of the dorsal spines is a single one, laid flat, and pointing for- 

 wards- 

 Three species inhabit the Mediterranean, all of which are 

 eatable, and already well characterized by Rondelet. 



L. amia; Scomber amia,L,.; the Vadigo, Rondelet, 254; Amia, 

 Salv. 121. The lateral line strongly covered or forming an S; 

 a large species more than four feet in length, and weighing a 

 hundred pounds. 



L. glauca; Sc. glaums, L. ; the Derbio, Rondel. 252. The 

 lateral line nearly straight; the anal and second dorsal marked 

 with a black spot in front; teeth small and crowded. 



L. sinuosa, Cuv.; Rond. 255. The blue on the back separated 



from the silvery hue on the belly by a zigzag line; the hooked 



teeth in a single range.(l) 



Lacepede separates from the Lichiae, by the name of ScoMpE- 



RoiDEs, which is not very appropriate, those species where the last 



rays of the second dorsal, and of the anal are divided into spurious 



fins, as in Scomber, properly so called. (2) The 



Trachinotus, Lacep. 



From which his Acanthrinions and Ccesiomores do not generi- 

 cally differ, are Lichiae with an elevated body, a more vertical pro- 

 file, and the dorsal and anal tapered into longer points. (3) 



Rhynchobdella, B1. Schn. 



Free spines ou the back as in Centronotus, and two free spines be- 

 fore the anal, but, as in a true Xiphias, the ventrals are wanting; the 

 body is elongated. They are divided into two subgenera. In 



notus sphwsus, Mitch., Ann. cit. Nov., I, iii, 9, which is probably the Gasteros- 

 teus canadensis, L. ; and some new species.
