This genus differs from C&ulolatilus and agrees with Latilus in the 

 small number of dorsal and anal rays, and is distinguished from both 

 by the presence of a large adipose appendage on the nape and by a 

 fleshy prolongation upon each side of the labial fold, extending back- 

 ward beyond the angle of the mouth. One species known. (A^<j,
