ACTINOPODOUS HOLOTHUEIOIDEA. 227 



description given of P. squamatus, is so close that I liave con- 

 sidered it safest to refer them to tlie present species. 



All the specimens are from 

 the Sagami Sea, and all from a 

 depth of 400 hlro ( = 333 fathoms, 

 a depth greater than that hitherto 

 reported). They possess ten ten- 

 tacles. The odd ambulacrnm of the 

 sole possesses some pedicels in the

anterior and posterior portions, but p , , ^ . 



^ -£ solus squamatus : Perforated plates 



is devoid of pedicels in the middle, "^ ^°^'^- ^ 200. 

 which is by far the largest part. Pedicels around the margin of 

 the sole are in 3 — 4 rows. Dorsal scales are beset with fine 

 grains. I can not find that they have any special arrangement 

 around the mouth or anus. The sizes of the specimens are : 

 7 X 2.5 cm.; 7x2 cm. ; 6.5 x 4 cm.; ßx4.5cm. ; 5.5 x 2 cm. ; 

 4x1.5 cm. The comparatively small widths are apparently due to 

 the lateral compression to v/hich the specimens had been subjected.
