found only on a few of the proximal joints; farther out generally 
only one scale remains, sometimes placed on the side plate (as in 
fig. 19), sometimes in the corner between the side plate and the 
ventral plate, as usual in species where only one scale is found. 
The ventral plates gradually change in form, from narrow, elongate, 
about twice as long as wide, in the inner part of the arm, to reet- 
angular, almost twice as wide as long, farther out (Fig. 19). The 
dorsal plates are, generally, more or less fanshaped, but upon the 
whole rather variable in shape; the proximal ones are rudimentary 
or, partly, absent, as pointed out by Fa rq uh ar. (Fig. 1 8 .i_ 2 , 4 _ 5 ). 
Some of the armspines show the characteristic feature of having a 
widened, slightly serrate distal edge in the basal part (fig. I 8 . 4 ); 
this feature is especially distinet on the second spine from below, 
and, apparently, does not oceur on the lowermost or the uppermost 
one. The lowermost spine is slightly curved. 
The figures of Åmph. aster given by Koehler (Op. cit.) offer 
so conspieuous differences from the characters to be observed in 
this species thai they must either be very diagrammatic or represent 
another species. 
The eggs are fairly large, ca. 0 , 15 —0,is mm, which may per¬ 
haps indicate that this species has not a typical Ophiopluteus-\?irwa.

This species, — besides Ophiocormus notabilis the only New 
Zealand Ophiurid not examined by the present author, — is very 
well distinguished from the oiher New Zealand Åmphiura!s through 
its two tentacle scales and the nearly naked underside of the disk. 
I have no remarks to offer to the careful description and figures 
given by Ben ham.
