intestines of all the soles they caught. It is very seldom that anything is found in the 

 stomach or intestine of a sole which can be satisfactorily identified. The stomach is 

 very slightly differentiated, it is only distinguished by the somewhat greater thickness 

 of its walls from the intestine, and is only marked off from the latter by a slight 

 pyloric constriction situated beneath the middle of the liver. The stomach after death 

 is almost invariably found empty. In the course of the intestine in a small percentage 

 of specimens small masses of the indigestible remnants of food occur. These masses 

 are usually black and enveloped in mucus. Usually they contain fragments of shells 

 with bristles of marine (Clia3topod) worms and other debris, and rarely something is 

 found in them whose specific origin can be recognised. The following is the record of 

 the intestines I have examined : —
