A lateral extrascapular is present on the posterior portion of the pterotic in P. brachyurus 

 (TS 77[ 1 ] ). The lateral extrascapular is a small bar-shaped bone bearing a part of the su- 

 pratemporal canal of the cephalic lateral line canal. No lateral extrascapular is present in 

 other species of Phoxinus and in the outgroups (TS 77 [0]). 



Occipital Region 



The occipital region is the most posterior region of the skull. It forms the posterodorsal 

 cover and the posterior wall of the braincase. Bones in the region include exoccipital and 

 supraoccipital. The former is paired, and the latter is single. The basioccipital will be de- 

 scribed in the basicranial region.
