IV. There Are Wishes which Have Subcutaneous Vessels 

 Among the Teleosts Also. 



Kishinouye stated repeatedly that the subcutaneous vessels are found 

 only in the Plecostei and that they are lacking in the Teleostei, however, 

 according to the results of my studies there are many teleostean fishes 

 which have subcutaneous vessels almost identical with those of the Plecostei 

 in the degree of their development and on other points. In what follows I 

 will cite several examples. 



a. Swordfish ( Xjphias gladius L.) (Figure 3) (Xiphiidae) 



In this species, as in the Plecostei, the dark red lateral tissue is 

 close to the spinal column. On the sides of the body near the lateral 

 line there are subcutaneous vessels consisting of one artery and one vein. 

 These vessels appear in the subcutaneous tissues directly posterior to_the 

 pectoral girdle and run longitudinally as far as the tip of the tail £?_/• 

 In an individual 150 cm long the artery and vein are respectively approxi- 

 mately 1 mm and 1.5 mm in diameter. The artery lies along the dorsal 

 external side of the vein. Both vessels send out small branches into the 

 dark red lateral tissue forming vascular plexuses like those of the 

 Plecostei. 



Unfortunately I cannot make any statement at the moment about the 

 relationship between the subcutaneous vessels in this species and the main 

 vascular system, chat is the dorsal aorta and the great vein, because when 

 these great fish are taken, the gills and other internal organs are .imme- 

 diately removed so that the carcass can be packed with ice and the fish are 

 brought to market with the main blood vessels already removed. 



b. Dolphin ( Cpryphaena hippurus L.) (Figure 7) (Coryphaenidae) 



This species possesses only the subcutaneous veins. These vessels 

 appear in the subcutaneous tissues immediately posterior to the pectoral 

 girdle and run along the lateral line as far as the tip of the tail 

 /'? caudal peduncle?/. These vessels appear to branch off from the 

 "Cuvierian ducts. 



c. Aomishimaokoze ( Gnathagnus elongatus (T. et S„)) (Figure 6) 



(UranoscopidaeJ 



This species has both subcutaneous arteries and veins. The arteries 

 branch off near the base of the subclavicular artery, pass beneath the 

 pectoral girdle, issue immediately to the subcutaneous tissues, and 

 parallel the lateral line as far as the tail. The veins come out of the 

 kidneys, pass beneath the pectoral girdle, issue thence directly to the 

 subcutaneous tissues, and proceed posterioventrally to a point between 

 the ventral fin and the anus. 



d. iiutsugoro ( Apocryptes chinensis Osbeck) (Gobiidae) 



This species has only the subcutaneous veins. The vessels branch 

 off from the sinus venosus and proceed go the vicinity of the dorsal fin»
