20 ART. 8. 1. IKEDA : THREE NEW AND 



The species is a remarkably large form. In PL I., fig. 3 

 is shown in natural size the smallest specimen I have obtained. 

 The body proper may measure 40 cm. in length and 2-3 cm. in 

 greatest width. The proboscis in the fully extended state may 

 be 150 cm. long and 1-11 cm. broad. So that, a large individual 

 w4ien fully extended may reach 190 cm. in total length. 



The general appearance of the proboscis has already been 

 described. Here it remains to be mentioned that the basal portion 

 of that organ, for a length of 5-8 cm. in front of the mouth, is 

 quite free of the transverse stripes on both surfaces and presents 

 a grayish to light-brownish yellow color, which deepens in tone 

 towards the position of mouth. At the transition of the proboscis 

 into the body proper, the former forms an incomplete funnel 

 around the mouth. The free distal end of the flat proboscis is 

 simply rounded. 



While in life, the worm incessantly changes shape and 

 dimensions by alternately contracting and stretching out, but the 

 shape given in fig. 3 may be considered to represent its normal 

 state of rest. In that condition the body is cylindrical and 

 broadest near the hind end, which is itself conically pointed. 

 Anteriorly it very gradually narrows towards the oral end. 



The skin presents a brownish red tint over a pale yellow 

 ground. It is thickly beset with small papillœ of a light 

 ochraceous color and of various shape and size. They are- largest 

 and most crowded near both ends of the body, where most of them 

 present a star-like and not a round outline. Except near the 

 body ends, there are seen on the surface narrow longitudinal lines, 

 in all five in number, running equidistant from one another. . The 

 lines are of a light yellowish color and are somewhat translucent ; 

 they can be best seen when the body is in a contracted state.
