 Snout short, with the cleft of the mouth oblique. Small teeth in the 

 jaws and on the vomer. Dorsal fin long, formed by spines only, and, 

 like the anal, continuous with the caudal ; a very large, excavated, 

 pen-Hke spine in front of the anal fin, hidden in a pouch ; ventrals 

 none. Gill-membranes united under the throat; pseudobranchisEi 

 small ; air-bladder none ; branchiostegals four ; pyloric appendages 

 absent.

The intestinal tract is wide and spiral ; there are no pyloric ap- 

 pendages ; liver and spleen large. The ovarium is situated on the 

 left side, simple, and, in the present state of development, is a large 

 sac with a glandular internal surface ; its external opening is situated 

 at the base of a small papilla, immediately behind the vent ; a furrow 

 leads from the opening to the groove of the spine before the anal fin, 

 which is evidently connected in some way with the generative 

 organs. The urinary bladder is situated on the right side, and has 

 externally the appearance of a coccum ; its aperture is at the tip of 

 the papilla.
