ACTINOPODOUS HOLOTHÜKIOIDEA.

61. Cticuînaria nozaivai, sp. n. 



(PI. I., fig. 12 ; textfig. 50). 



Specimen examined:— One alcoholic specimen from Isliizaki, Prov. Osliima, 

 Hokkaido. Collected hj Nozawa in July 1890 (Sei. Coll., Spec. No. 1085). 



Description :— The specimen, which shows many wrinkles and 

 is undoubtedly much contracted, is barrel- shaped, i.e., bluntly and 

 broadly truncated at both ends. 



There are no pedicels in any of the interambulacra, either 

 dorsal or ventral. There 

 are two rows of pedicels 

 along each ambulacrum, 

 in which I am able to 

 count about 42 pairs of 

 them. The skin is soft 

 and pliable, although 

 the scissors, in cutting 

 it, make a slight gratinor 

 sound, indicating that 

 calcareous deposits are 

 numerous. Polian vesicle 

 one, vesicular, attached 

 to the ventral median 

 radius. Stone-canal one, 

 attached to the dorsal 

 mesentery. Eespiratory 

 trees present. Tentacles
