been unable to find the exact point of union, but am inclined to 

 believe that the thyroid vessel is the one that communicates 

 with the venous system. For a short distance each pharynx 

 lymphatic vessel runs along the ventral surface of the combined 

 trunk of the third and fourth nutrient branchial veins, and at 

 this point several dorsal branches are given off, but they ap- 

 parently go to the posterior end of the thyroid. The largest of 

 them, however, leads into the sinus situated at the base of the 

 second branchial arch.

Fig. 9. Ventral view of the large pericardial lymphatic sinuses surrounding 

 the heart. Only a portion of the ventral pericardial sinus is figured. In this 

 specimen the two interlinking arms between the ventral pericardial and the peri- 

 cardial sinuses had no additional connection with the posterior portion of the 

 pericardial sinus as it has in some specimens, shown in Fig. 10. Medium large 

 Scorpcenichthys. Natural size. 



It is of interest in this connection to again note that Vogt (i, 

 p. 138) in the salmon describes one of the 2 dorsal lymphatic 

 trunks of each branchial arch*, which terminates in the cephalic 

 sinus, as being prolonged ventrad and anastomosing with the 

 veine de Duvernoy (inferior jugular), and from Vogt's descrip- 

 tion it is perfectly clear that he has not confused the nutrient
