the distal edges of the brachials, and not to the perisomic webbing along the sides of 

 the arms as Carpenter had supposed. He recorded this form, which he gives as a 

 subvariety of Actinometra echinoptera var. pulchella, from a number of different 

 stations. 



In studying the West Indian comatulids collected by the Albatross I found a 

 highly ornate form of Neocomatella pulchella, and, misled by Carpenter's interpreta- 

 tion of the origin of the name alata, I never thought of comparing it with this type, 

 but in 1917 described it as new under the name of Neocomatella ornata. After the 

 return of the Blake material I visited the Museum of Comparative Zoology and 

 examined the specimens, making the discovery that my ornata was identical with 

 Pourtales' alata described almost 40 years previously.

Diagnostic features. The cirri are rather slender, with relatively few segments, 

 of which the proximal are much elongated, the fourth, which is the longest, being 

 four times as long as broad, or even rather longer. The cirri are XXIII-XXVIII, 

 13-15 (usually 14-15); the arms are usually 20, in the material which I have studied 

 up to 50 mm. in length. 



Description. The centrodorsal is broad, flattened, and sometimes even depressed. 

 The cirri are marginal. 



The cirri are X XXVIII, 13-15; the first segment is very short, the second is 

 slightly longer, the third is much longer, and the fourth is longer still, from three 

 to four times as long as broad; the fifth is slightly shorter, of the same length as 

 the third, and the segments following decrease regularly in length, though they
