In spite of some rather important differences from the description 
the two specimens in hånd must 
species, which was known hitherto 
only in the single specimen obtained 
by Mr. Suter in Akaroa Harbour. 
The most conspicuous difference 
is found in the shape of the calc- 
areous ring. As a comparison of 
the figure given here with that of 
Dendy & Hindle (PI. 11, fig. 8) 
will show, the interradials differ 
very markedly from those in Dendy 
& Hind le’s figure. I cannot 
give any explanation of the differ¬ 
ence but must simply State that in 
both my specimens the calcareous 
ring has the shape shown in fig. 36. 
The tentacles of the type spe¬ 
cimen were twenty; one of my 
specimens has only 18 tentacles, 
only 4 pairs of the large tentacles 
being developed. This is probably 
simply an individual abnormality. 
They are more or less unequally 
developed in all pairs; the ventral 
pair is considerably smaller than 
the others. 
While the skin of the body is 
totally devoid of spicules, as was 
also the type-specimen, I find spi¬ 
cules well developed in the anal extremity of the present specimens. 
They are tables, wiih a spire of two columns, ending in some 8—12 
tho ns. The disk has generally 8 holes, 4 inner, somewhat larger 
and 4 outer, smaller ones, alternating with the former. The edge 
of the disk is perfectly smooth (fig. 37.a). No distinet anal teeth. 
The tentacles contain rather numerous spicules, thin rods with a 
hole or two in each end (Fig. 37.b). The tubefeet are devoid of

Posteriorly the pharynx is seen con-
