Trigla, placed by Cuvier at the head of the family, is, in fact, the genus in 

 which the sub-orbitars most completely cover the cheek, these bones being arti- 

 culated anteriorly to the snout^ projecting more or less beyond it, and united so 

 firmly posteriorly to the preoperculum that it moves along with them. It belongs 

 to the group having a parallelopipedon head and two dorsal fins, being, with its 

 two sub-genera, distinguished from the rest 6f the group by the presence of free 

 rays under the pectorals. The Trigla, as we have noticed in the preceding pages, 

 have a wide range in the Mediterranean, and on the European side of the Atlantic, 

 from the Canaries to Norway. One species, at least, ranges also to the American 

 coast, for a Trigla pini, or one so like it that no distinguishing marks could 

 be perceived in the prepared specimen, was sent to Baron Cuvier from New 

 York ; and as this species ranges on the European side as high as the Dutch coast, 

 it is probable that it extends on the American one to Nova Scotia or Newfound- 

 land ; but until it has been actually detected on the coasts of British America, it 

 would not be proper to enumerate it in our Fauna. The sub-genus Prionotus, 

 distinguished by the presence of palatine teeth, en velours, belongs entirely to 

 America, and though three of the four known species reach New York, yet their
