1. Represents a general superticial lateral view of the tail of a median sized 

 Scorpffinichthys as viewed from the left side when the skin only is removed. The 

 origin of the lateral lymphatic trunk from the surface of the myotomes and the 

 posterior portion of the lateral lymphatic trunk from the fascia and the intrinsic 

 muscles of the caudal fin is clearl}' shown. XI. Reduced 1 



2. Is a somewhat similar dissection of a median sized Ophiodon elongatus tail 

 as seen from the right side. Introduced mainly to illustrate the peculiar fan- 

 shaped network of the posterior portion of the lateral lymphatic trunk on the 

 fascia. X 2. Reduced ^ 



3. Dorsal view of a diagrammatic reconstruction of the longitudinal neural, 

 lateral, and cau<lal lymphatic trunks taken from a transverse series of sections 

 through the tail of a 28 mm. adult Clinocottus analis. This species differs from 

 Scorpainichthys in having the posterior portions of the lateral lymphatic trunks 

 in direct communication with the posterior caudal sinus. X 50. Reduced i
