Figure 8. — Pseudoceros habroptilus, entire animal. (Explanation on page 597.) 



General characters: The preserved worm is of oblong shape, 

 20 mm. long by 12 mm. wide. The tentacular foldings are prominent 

 (fig. 9a), but because of the black color the eyes could not be seen 

 in the cleared worm. The color is described by the collector as 

 velvety black with a narrow, brilliant blue border. Some trace of 

 the blue border remains in the preserved worm. The pharynx was 

 not detectable. There is a single male apparatus with the male pore 

 located 5 mm. from the anterior end. The female pore occurs close 

 behind the male pore. The sucker is located at about the body 

 middle, 10 mm. from the anterior margin.
