Stat. 273. Anchorage off Pulu Jedan, eastern coast of the Aru Islands (Pearl Banks). 13

The specimens from Stat. 273 exactly resemble others from northwestern Australia; the 
arms are stout, basally strongly flattened laterally, and very rugose; the development of the 
lateral processes on the pinnule segments is very strong. One very fine typical e.xample has 
22 arms 120 mm. long; all the IIBr series are 4 (3 + 4); both the IIlBr series are 2, internal; 
the colour is white, the outer part of the pinnules and cirri violet. Another has 20 arms iiomm. 
long; two of the IIBr series are absent; all the IIBr series are 4 (3 + 4); the two IIIBr series, 
both internally developed, are 2 ; the colour is similar to that of the preceding, with in addition 
a few narrow purple bands and blotches on the outer part of the arms. A third has 16 arms 
120 mm. long; there are five IIBr 4 (3 + 4) series, and one IIIBr series of 2, internally developed. 
A fourth has 16 arms 115 mm. long; there are six IIBr 4 (3 + 4) series. The three remaining 
examples are similar. 
The two from Stat. 274 are small; the larger has 13 arms 75 mm. long; there are 
three IIBr 4 (3 -1- 4) series on three separate rays; the colour is flesh-coloured, with regular 
narrow purple bands on the arms.

The cirri are VIII — XIII, 24 — 36 (usually 30 — 33), 26 mm. to 32 mm. (usually about 
30 mm.) long; they are very slender, and taper gradually in the proximal third, being especially 
slender from that point onward. In general they recall the cirri of Leptometra celtica. All the 
cirrus segments are approximately subequal in length, about twice as long as broad at the ends, 
though those in the distal third of the cirrus are slightly carinate, which makes them appear 
slightly shorter, and those in the pro.ximal half are slightly longer, with slightly expanded ends ; 
on the outermost segments there is a slight indication of dorsal tubercles.
