 The other hyoid elements are normal. Six branchiostegal rays 

 are present ; two are attached to the outer surface of the epihyal, 

 two to the outer surface of the ceratohyal, and two to the inner 

 surface of the ceratohyal. In Gobiesox the urohyal and glosso- 

 hyal are better developed, the former being scarcely reduced.

 the cranium. A short epiotic process projects over its head, and
