Among the above-mentioned stations, some will be noticed where the depth 

 is fairly great; such is the case with the stations 2.369-2.374 (66 fathoms), 2320 (130 

 fathoms), 2357 (178 fathoms), and 2327 (182 fathoms). But it is already known 

 from elsewhere that 0. angulata may go down fairly deep, and VerrUl has reported 

 it at 200 fathoms off Havana. The specimens coming from deeper waters than 

 100 fathoms are lightly colored, grayish, greenish, or somewhat pink. 



The specimens from stations 2369-2374 are very small, and the diameter of their 

 disks ranges between 2.2 and 2 mm. They are greenish-gray, and then- brachial 

 spines are fairly large; they offer a superficial Ukeness to 0. pallida, of wliich I have 

 recently given a new description from the only example known up to the present 

 day (13, p. 377). But, after having compared them very carefully with the type 

 of that species, I have satisfied myself that they actually are 0. angulata; for the 

 radial sliields are smaller than in 0. pallida.; the upper and under brachial plates, 

 although fairly elongated as they always are in very young 0. angulata, are, 

 however, less so than ui 0. pallida; the first under brachial plates, especially, are 

 first a little wider than long, then they progi-essively grow longer, but they do not 

 become longer than wide until within a certain distance from the disk; lastly, 

 the first ventral spine changes into a hook only at a fairly great distance from the 

 basis of the arms. 



The young 0. angulata always have their under and upper brachial plates 

 longer than those of the adults, and dorsal spines which become very much elongated 

 in the terminal part of the arms.
