4. ACANTHORHINUS. 



Head flat. Nostrils near the fore end of the snout. Corner folds 

 of the mouth naked, very large and deep. A slit of the skin pro- 

 ceeds backwards from the same. Spout-holes behind and above the 

 eyes, with a flap. The fourth and fifth gill-holes are approximated 

 to each other. Teeth in the under-jaw as in Acanthias, but with 

 the edge less lying; this is either indistinctly toothed or entire. 

 The root has a middle upright keel with a cross lobe on the outer 

 side standing forwards. The upper teeth straight, equilateral, 

 three-cornered on a four-sided base, with a longitudinal keel and a 

 cross one ; no denticulations and no supplementary prongs. The 

 longitudinal keel is continued over the fore surface of the tooth, 

 whereby it becomes thicker in the middle. No middle-tooth. No 

 tail-pit. The males have a prickle in their appendages, which is 

 placed on their outer side before their ends.
