arm, to which adheres posteriorly a group of two or 

 three others, occupying the place of the fore-arm, 

 and bearing the pectoral fin, which may be considered 

 as the hand; lastly, there is almost always sus- 

 pended a style, composed of one or two bones, 49, 

 50, which Baron Cuvier regards as the analogue of 

 the coracoid bone. The uppermost of these first 

 three bones, 46, is usually forked, and attached by 

 its two crests to the lateral crests of the cranium. It 

 shews itself externally at the top of the branchial 

 opening, resembling a scale, larger than the others, 

 and sometimes toothed along its edges . The second, 

 47, continues along the margin of the branchial 

 opening. The third, 48, always the largest, com- 

 pletes the cincture by uniting with its counterpart 

 beneath the throat. To the inner surface of the 

 last mentioned bone adheres a fourth, 51, and a 

 fifth, 52, placed one above the other. The free 

 side of these bones bears the pectoral fin, but by 

 means of an intermediate range of four or five small 

 bones, 53. These little osseous pieces may be 

 supposed to represent the carpal series ; and if so, 

 then the two others, 51 & 52, will be the cubitus 

 and radius. The third bone of the cincture, 48, 

 which supports the two last named, will then neces- 

 sarily represent the humerus, and the first and 

 second, 46, 47, the shoulder blade. The style 

 above alluded to, is shewn at 49 & 50. 



To the outer edge of the so called radial and 

 cubital bones adhere the small flat bones supposed 

 to represent the carpus, 53 (see cut of Vertebrae). 

 Their function is to support the rays of the pectoral
