 epiotics and the supraoccipital. In consequence of this median union the supra- 

 temporal commissure is completely enclosed by bone. The latter canal opens to 

 the surface by a few posterior pores. The main lateral line pierces the ventral surface 

 of the supratemporal. 



The post-temporal is composed of a main body which bears three processes. The 

 body of the bone is a small flat plate on the underside of which there is a small 

 depression which receives the dorsal end of the supracleithrum. The lateral line 

 runs through the lateral margin of the post-temporal. Two of the three processes
