11. Portion of the tail of a 30 mm. living embryo Phanerodon atripes (Viviparous 

 perch) as seen in a watch glass of sea water under a microscope . The blood cor- 

 puscles were plainly seen passing out of the caudal.artery into the dorsal and ven- 

 tral caudal fin arteries, thence into the caudal fin ray arteries, Irom which they 

 entered a minute capillary network lying in the membrane connecting two rays. 

 On the opposite side these networks were collected by corresponding caudal fin 

 ray arteries, which emptied into the dorsal and ventral caudal fin veins, the latter 

 uniting to form the main caudal vein. X 33. Reduced | 



12. Transverse section through the caudal peduncle region of a 28 mm. adult 

 Clinocottus analis. All of the main longitudinal trunks are seen in section. The 

 posterior neural and haemal trunks are also seen in section midway between the 

 longitudinal neural and the dorsal trunks, and between the longitudinal hajmal 

 and the ventral trunks. X 25. Reduced |
