In this specimen the 20 arms are 115 mm. long; the llat dorsal pole of the centrodorsal 
is 2 mm. in diameter; the cirri are XXXIII, 20 — 21, 20 mm. long; P, is 15 mm. long with 
15 — 16 segments of which the fourth and fifth are the longest; on the inner arms P., is 12 mm. 
long, though composed of the same number of segments. P„ is relatively slender, much less 
spine-like than usual, more fle.xible basally, becoming very slender distally; the three basal 
segments are about as long as broad, the fourth about one third again as long as broad; the 
remaining segments are elongated. 
This specimen appears to be identical with Hartlaub's specimen of iiioiiacantha from 
Torres Strait. It also agrees with specimens of indica at hand from Ceylon, and with others 
from Madagascar which I have examined, though the size is somewhat greater. 
There can be little doubt that the specimen taken by Dr. H. L. Cl.vrk at Maer Island, 
Torres Strait, and recorded by him as 5. mojtacantha, belongs to this species.
