of Edinburgh, Session 1883 - 84 . 
Colour, yellowish-grey, with five rather indefinite radial markings 
on the dorsal surface of the disk. 
The typical Amghiura bellis differs from this in having one short 
stout blunt papilla on either side of the base of the mouth angle. 
It has also suhtriangular mouth shields, and the lateral mouth 
shields do not meet each other in the middle line. 
The mouth papillae are of a different shape. A first under arm 
bone is present, and the tentacle scales of the first pair are spini- 
form and rather conspicuous. 
This single specimen is worthy of special notice, because the 
species has been only known hitherto from specimens collected by 
the “Challenger” at Stations 174, near the Fiji Islands, and 232 
and 236, off Japan. It is interesting to notice that Aster onyx 
Loveni is also common to the north European seas and those of 
Japan, and a relation has been traced by Drs Gwyn Jeffreys, 
and Gunther between the mollusca and fishes of Japan and the 
North Atlantic and Mediterranean.*

The mouth shield has the inner angle almost a right angle ; 
the outer edge is not nearly straight, but with a re-entering angle. 
The teeth papillae are usually four. As in Professor VerrilFs 
specimens, the arms have all been broken ; the longest measured 
twice the diameter of the disk. The arm-spines are three ; the 
uppermost is the longest, and is a little longer than the arm-joints, 
and the second is about two-thirds the length of the first; the 
third is still shorter ; the tentacle-scale is close to the arm-spines, 
and appears to form part of the same series with them ; there is 
only one tentacle-scale, except in the proximal portion of the arm, 
where there are two ; where this is the case, the outer is spiniform, 
the inner scale like. The margin of the genital slit is finely 
serrated. The two or three proximal tentacle pores have some- 
times three tentacle scales, close beside which are two small spines, 
about equal to them in size.
