If. MATSUMOTO : A NEW STALKED CRINOID. 



ther. The circlet of first radiais is 6. mm. in diameter at the upper 

 border. The second radiais have strongly convex external surfaces, 

 and present nearly semicircular articular surfaces both above and 

 below ; each second radial is 1.7 mm. high, 3 mm. wide, and 1.7 thick. 

 They articulate with the first radiais, but do not stand in contact 

 with one another. The remaining parts of the animal are wanting in 

 the unique specimen before me. 



The colour of the dry specimen is a dull yellowish brown. 



Locality : Okinosé, off Misaki in the Sagami Sea ; depth about 

 330 fathoms. 



The present species differs from the genotype, Ph. nudus CLARK, 

 chiefly in the more convex external surface of the columnals, in the 

 long axes of the upper and lower articular surfaces being disposed not 

 always at right angles as the result of the twisting of the stem, and 

 in the basais being pentagonal, instead of triangular, in shape.
