TELEOSTEI 



possessing compound vertebrae, abbreviate heterocercal tail, ganoid 

 scales with peg and socket articulation, fulcra, and possibly a 

 splenial and supra -angular, it becomes obvious that the group 

 ([sospondyli) can no longer be fitted into any phylogenetic scheme. 

 The Leptolepidae, however, may be classed as primitive Teleosts, 

 and the remaining families can be grouped together into various 

 sub-orders with considerable confidence, but of the relationship 

 between these sub-orders, of their exact position on the phylogenetic 

 tree, we know as yet comparatively little.
