64 ART. 4. T. IKEDA : 



the proboscis, when fully extended, is as long as 100-150 cm. 

 The body proper is of a deep reddish brown color ; the proboscis 

 bears narrow transverse stripes of brown. The papillae are ir- 

 regular in shape, and are largest and most closely crowded together 

 at both ends of the body proper. The ventral hooks are relatively 

 small and brownish yellow in color. In the fresh state, there 

 are seen on the body proper five narrow longitudinal stripes of 

 a pale yellow color, corresponding to special thickenings of the 

 longitudinal muscle. The bulbous bases of the paired hooks are 

 joined by a slender interbasal muscle. The alimentary canal 

 pursues a course which is peculiar to this species. The pharynx is 

 accompanied by two large wing-like muscles. The anal glands are 

 6-7 cm. long, fixed at the apex by a long muscle ; they appear 

 to be hairy on account of the presence of very long funnels. 

 No rectal gland is present. As the heart lies in a very posterior 

 situation, the dorsal vessel is remarkably long. The segmental 

 organs are extremely abundant ; in the larger specimens, they may 

 number not less than 200 on one side of the ventral nerve-cord, 

 arranged not in pairs but apparently without order. They are 

 small, measuring 10-12 mm. in length ; the internal opening 

 si terminal in position. 



Habitat : The species inhabits shallow muddy bottoms in 

 deep vertical holes, from the opening of which the long worm- 

 like proboscis is extruded. It has hitherto been obtained at 

 Tsushima ; Bay of Amakusa (Kiushifl) ; Tomo and many other 

 localities in the Inland Sea ; Tateyama (Bôshiù) ; Haneda (Tokyo 

 Bay) ; and Misaki. In the last locality the species is common.
