Their premaxillae are not fused to the surrounding bones, but they form a complete ring around the narial opening. |
|
The tapering anterior end of the vomer enters between the premaxillae, forming a loose contact that results in slit-like fontanelles on either side. |
|
The dorsal processes of the premaxillae are apomorphic, being longer and more vertical than those of any extant or fossil salmonine. |
|
Maxillae and premaxillae brown with little cream spots, and with two irregular cream lines that are between the anterior border of eye and tip of the snout. |
