tapering, with about eight joints; next four pinnules similar, then 
gradually increasing in length, reaching 12 mm. distally; the distal 
pinnules have twenty-five or twenty-six joints, the first two of 
which are short and rather broad, the remainder about half again 
as long as broad, becoming twice as long as broad in the terminal 
portion. The disk is very deeply incised; the anal tube is very 
long and slender. P, on the outer side of each III Br series is 
much larger than the corresponding pinnule on the inner arms, 
or than P, on the same arms, as noticed by Hartlaub. 
Color (in spirits). Deep violet, the rays and division series 
With perceptibly darker lateral lines; the containing alcohol is 
stained light red. 
June 15, 1905. Three specimens; one has sixty arms 
105 mm. long, cirri XXII, 45—60, 50 mm. to 60 mm. long; the 
anal tube is 15 mm. high; the outer branches from the IIBr 
series have, as usual in this species, one more axillary than the 
inner; colour nearly white, the perisome light brownish gray, the 
rays and division series with traces of slightly darker lateral lines. 
Another has sixty-five arms 130 mm. long, cirri XL, ca. 70, 
60 mm, to 70 mm. long, P, 20 mm. to 22 mm. long with thirty 
joints, P, 4 mm. long with eight or nine joints; the anal tube 
reaches to a height of 15 mm. above the disk; the colour is deep 
violet; the third specimen is represented by a calyx, centro-dorsal, 
and arm bases of a medium sized example; the disk has been 
lost and is just beginning to regenerate, having reached approxi- 
mately the stage figured by Bell in the type of Zygometra micro- 
discus, which species was so named through misconception of its 
structure, 
June 6, 1904. One specimen with 70 arms about 120 mm. 
long, and cirri 60—70 mm. long. 
A specimen of this species taken in the Philippine Islands 
by the U. S. Fisheries steamer "Albatross” has about one hundred 
and twenty arms.
