lateral than in the median line, almost entirely united laterally; 
I Br axillaries low-triangular, laterally about as long as the IBr,, 
about three times as broad as the median length, well separated 
laterally; six IIBr series developed, all 4 (3+-4); each II Br 
series bears two IIIBr series (twelve in all) of 2; one IIIBr 
series bears a IV Br series, 2, on the inner side of the II Br ax- 
illary (and outer side of the following III Br axillary); division 
series well separated, rounded dorsally, the sides smooth without 
lateral projections or carination; the first joints of the two divisions 
following each axillary are united interiorly. 
Twenty-nine arms 130 mm. long; first eight brachials ap- 
proximately oblong, about three times as broad as long, then be- 
coming obliquely wedge-shaped, almost triangular, about three times 
as broad as long, then becoming less obliquely wedge-shaped and 
almost short oblong or discoidal in the outer half of the arm, 
though never regularly short-discoidal as in Himerometra; brachials 
slightly overlapping. 
On an arm arising from a IBr axillary P, is 9 mm. long, 
moderately stout basally, but tapering rapidly, becoming slender 
and almost flagellate in its distal half, with twenty-eight joints, 
the first broad and large, about twice as broad as long, the second 
smaller but similarly proportioned, the third slightly longer, the 
following similar to the third, but becoming short in the distal ten 
or twelve; the larger proximal joints are moderately carinate, the 
carination being somewhat roughened and finely tubercular; P, is 
13 mm. long, stout basally, tapering to a slender tip, with thirty- 
one joints, those in the proximal half rather strongly carinate, not 
so long as broad, then becoming squarish, the carination diminishing, 
and short in the terminal portion; P, 21 mm. long, stouter than 
P,, tapering evenly to a slender tip, with thirty-eight joints, the 
majority of which are squarish, rather shorter basally, rather longer 
distally; the joints in the proximal half have somewhat tubercular 
carinate processes, which, bowever, are: never very large, and there 
is a prominent ridge running along the entire pinnule distal to the
