7. The fore edge of the head straight, transverse. The cranial- 

 fins spring from the under edge of the root of the breast-fins, and 

 stand like ears on the sides of the head. The outer edge of the 

 head-fin is curled upwards and inwards. The mouth before or 

 beneath, very broad, reaches nearly to the ears. The under edge of 

 the conjoined nasal-flaps straight. The nostrils wide, outwards, 

 near the head-fins. Teeth very small. The eyes lie on the side of 

 the skull, and the fore edge of the breast-fins begins behind them. 

 The spout-holes, situated on the dorsal surface of the body, are 

 separated from the eyes by a wide interspace. The tail is as long 

 or longer than the body, and bears a back-fin behind which there is 

 a spine. — Cephaloptera.
