VznniLL.— Descriptions of new Star-fishes from New Zealand. 281 
others of similar form not half as large. Those in the ambulacral furrows 
are even longer, but more acutely pointed. The madreporie plates are 
variable in number and size as well as in position. One appears to be 
always in its normal position and near the edge of the disk, while the 
accessory ones are introduced at various points around the disk, but at 
about the same distance from the margin. Sometimes, when there are but 
two and the rays are in even numbers, they are directly opposite and in the 
same transverse plane. A specimen with eleven rays has two contiguous 
ones and another separated by four rays, each being composed of several 
pieces united. One specimen has but one large convex madreporic plate. 
The largest specimen is 7:5 inches in diameter across the rays, with a 
disk 1:25 inch in diameter; rays, ‘5 inch broad; inter-ambulacral spines, 
*15 inch long.

AsTERINA (ASTERISEUS) REGULARIS, Verrill. 
Pentagonal, depressed, with the inter-radial spaces evenly coneave, and 
the rays short, broad and acute; greatest radius to least as 15 : 10. Ambu- 
lacral pores large; inter-ambulacral plates each with two slender acute spines, 
forming a single row. Those near the mouth larger, obtuse, and flattened. 
Ventral plates of the first row stout and prominent, each bearing a conical, 
acute spine, twice as large as the preceding. Exterior to these the ventral 
or inter-radial plates are flattened or imbricated, diminishing in size as they 
recede from the centre, each bearing an acute conical spine; these diminish 
in size like the plates, the larger ones being about as thick as the inter- 
ambulacral spines, but shorter; near the margin these spines become very 
small and crowded, many of the plates bearing two. Plates of the upper 
surface rather large, increasing towards the centre, regularly imbricated, 
the free margin evenly rounded and thin, bearing near the end a cluster of 
five to nine very small, nearly equal spines ; towards the centre the plates 
become less regular in form and unequal in size, the larger ones often 
bearing twelve or fourteen spines in a transverse cluster. Madreporic plate 
large and prominent, at about one-third of the distance from the centre to 
the margin. The large dorsal pores are in groups on the sides and within 
the bases of the rays, arranged in about four rows, which run parallel with 
the median line of the rays, with from six to twelve pores in a row. A few 
irregularly arranged pores "between adjacent rays connect these groups. 
Colour, when dried, dark olive green above, yellow below. From centre 
to end of ray, 1:5 inches; to edge of disk, :8.

ASTROPECTEN EDWARDSII, Verrill. 
Rays five, long, regularly tapering, acute, about four-and-a-half times 
as long as the radius of the disc. Ambulacra broad, inter-ambulacral plates
