SOME NEW SCYPHOMEDUSJE OF JAPAN. 



in a single row. New genital sacs are added at the distal end 

 of the genital gland. 



The color is generally dark brown necked with white. The 

 adhesive anchors and the base of the peduncle are light red. 

 The genital glands and the tip of the secondary tentacles present 

 a dark brown color. The manubrium is yellowish, while the 

 snbnmbrella is pale green. 



The size of a fall-grown animal measures 25 mm. in length, 

 excluding the peduncle. 



A specimen of this interesting medusa was first discovered 

 by Mr. Masamabu Inaba in 1893 at Kata-ura in the Province 

 of Kii. It was kindly given me for examination, together with 

 the sketches and notes made by the discoverer. On account of 

 the peculiar shape and movements of the animal Mr. Inaba at 

 first took it for a worm. Some years since the same medusa was 

 found near the Marine Station at Misaki during winter months. 



The animal hangs down from the frond of Sargassum on 

 which it is attached. It can detach itself of its own accord, but 

 is devoid of swimming power. Being remarkably contractile in 

 both umbrella and peduncle, the body-length is reduced by 

 almost one half when contracted. As the body has adhesive 

 apparatus at both its extremities, it can effect a locomotion very 

 much like that of a leech.
