and first three brachials have produced, thin, and everted lateral 
edges, those of adjacent joints in close apposition and flattened: 
against each other, very crenulate anterior and posterior edges, often 
dovetailing more or less, and rounded median ridges; the following 
5 or 6 brachials are alternatingly tubercular, this feature being more 
or less pronounced, and sometimes almost obsolete in the smaller 
specimens; the fourth to about the twelfth brachials are wedge-shaped. 
broader than long, then becoming triangular and as long as wide, 
this continuing almost to the tip of the arm; the terminal brachials 
are quadrate, and finally elongate. Syzygia occur between the third 
and fourth brachials, again at about between the fifteenth and six- 
teenth, and distally at intervals of from 5 to 11 (usually 5 to 7) bifas- 
cial articulations. The brachials are, all but those at the base of the 
arms, rather strongly overlapping with finely serrate edges; the costals 
and lower 6 or 7 brachials are very sharply “ wall-sided ” and flattened 
against each other; the lower 10 to 15 brachials have more or less de- 
veloped thin lateral flange-lke processes, most developed in the pos- 
terior part; the lower brachials also have single small rounded tuber- 
cles developed on alternate sides of the median line, which may persist 
almost throughout the length of the arm. 
The first two pinnules are somewhat longer, and more slender than 
their successors, and are composed of a greater number of smaller 
joints; the following pinnules are very stout in the basal half, then 
taper to a slender tip, the expansion of the basal joints gradually be- 
coming less and less marked distally. 
Color (in life)—Arms ochre yellow; cirri clear lemon yellow 
(Fisher). The containing alcohol is stained either a deep orange-red 
or emerald green. ?

Two young specimens, arms 25 mm. and 80 mm. long. 
Remarks.—In the specimen with arms 80 mm. long both costals are 
visible, and the ends of the basal rays are prominent as vertically 
elongate tubercles in the angles of the calyx; the very broad character 
of the costals and lower brachials is very marked, as in the eversion
