tion of the remaining rays. On the left ceratohyal 

 of the 61 mm cleared and stained specimen of T. 

 ocellatum (Figure 10), the fifth branchiostegal ray 

 is bifurcated at midlength, giving the impression 

 of having seven total rays. 



A small, triangular basihyal is present (Figure 

 10). The urohyal is absent in all lophiiforms. 



Opercular apparatus (Figure 9). — The opercle is 

 triangular in shape with a slightly concave poste- 

 rior margin. An elongate, crescent-shaped sub- 



opercle lies medial to the ventral tip of the opercle. 

 A subopercular spine is absent. The interopercle is 

 large, flat, and broad. The crescent-shaped pre- 

 opercle is also large, strengthening the entire 

 length of the suspensorium. 



Branchial arches (Figure 11). — There are three 

 pharyngobranchials. That of the first arch is a 

 small, toothless, suspensory pharyngobranchial; 

 those of the second and third arches are consider-
