Fig. 82. Albula vulpes (Linnaeus). Pectoral girdle of right side in medial view. 

 Composite of several B.M.N. H. specimens. 



A small gular plate is seen in some specimens (Nybelin 1960), notably the larger 

 individuals. Unlike the gular plate of other albuloids that of A. vulpes is vertical. 



Paired fins. All bones composing the pectoral girdle (Text-fig. 82) are stout. The 

 main body of the post-temporal is longer than wide and is produced into three pro- 

 cesses, an epiotic (dorsal) limb, an intercalar (ventral) limb and a third limb which 

 projects into the lumen of the post-temporal fossa and is embedded within epaxial 

 musculature. The supracleithrum is the usual elongate element. 



Many features of the ventral parts of the pectoral girdle are similar to those of 

 Pterothrissus. The cleithrum is broad above the fin insertion but becomes narrow 

 antero-ventrally ; the coracoid does not extend to the tip of the cleithrum ; an 

 interosseous foramen is absent (in Pterothrissus it is very small) ; the scapula fails
