Straits of Formosa; 35 fathoms. . The type. … This 
specimen has eleven arms 70 mm. long; first brachial wedge-shaped, 
rather longer outwardly than inwardly, united inwardly for the entire 
length; second brachial similar in shape and size, but not united 
inwardly with its fellow; third and fourth brachials. (syzygial. pair) 
oblong, about twice as broad as long; next two brachials oblong, 
about three times as broad as long, then becoming wedge-shaped, 
and triangular, about half again as broad as long, after the tenth; 
terminal four to six brachials very short, abruptly incurved,… the 
terminal. pinnules reaching about 4 mm. beyond them as in. the 
other species of the genus. IBr and first nine or ten brachials 
in close apposition laterally, sharply ,,wall-sided"; arms in the 
proximal half rounded dorsally, but after the middle gradually 
becoming compressed and strongly carinate, the brachials developing 
strong overlapping spines. Syzygies occur between the third and 
fourth brachials, again between the fifth and sixth to thirteenth 
and fourteenth (usually between the twelfth and thirteenth or 
thirteenth and fourteenth, with sometimes an extra one between 
the seventh and eighth) and distally at intervals of four to seven 
(usually five or six) oblique muscular articulations. 
The most obvious distinguishing characters of this species are 
the small rounded-conical centro-dorsal,. bearing comparatively small 
Cirrus sockets, and the smoothness and slenderness of the lower 
part of the animal. From the base of the centro-dorsal the increase 
in width is gradual and regular, reaching a maximum at about 
the level of the first syzygy. In A. macropoda and AÅ. anthus 
the cirrus sockets are much larger, the centro-dorsal is columnar
