ME. H. FAKQUHAR 01^" NEW ZEALAND ECHINODERMS. 191 



D'Urville Island ; and Mr. Haylock has collected half a dozen 

 specimens under stones at low water near "Wellington. The 

 colour in life is chocolate or bright reddish brown above, with a 

 ten-rayed blackish star on the disc, and the upper surface of the 

 rays is sometimes blackish, and the actinal surface pale reddish 

 or purplish. 



Amphifra pusilla, sp. n. (Plate 14. figs. 1, 2, 3.) 



The disc is rather tumid, circular, with a wavy margin ; it is 

 covered with rounded, imbricating, somewhat irregular scales, 

 which decrease much in size near the margin of the disc. The 

 scaling on the actinal surface is much liner and more regular than 

 that on the abactinal surface. The radial shields are pear-seed 

 shape, about twice as long as broad, separated their whole length 

 by a wedge of scales. The arms are short, about four times the 

 diameter of the disc. There are a pair of short, blunt, stout, 

 rounded mouth-pap illse at the apex of the mouth-angle, and one 

 on either side at the base, which is short, blunt, and leaf -like. 

 The first tentacle-scale is long and spiniform. The mouth-shields 

 are roundly heart-shaped, as broad as long. The side mouth- 

 shields are rather large and broad ; they do not meet within. The 

 under arm-plates are squarish, with rounded angles and slightly 

 re-enteringly curved sides ; they do not nearly extend across the 

 width of the arm. The upper arm-plates are elliptical, broader 

 than long, almost covering the upper part of the arm. The side 

 arm-plates bear six short, rather stout, bluntly-pointed, subequal 

 arm-spines, the uppermost somewhat smaller than the others and 

 directed upwards. Each tentacle-pore is covered by one large, 

 plain, rounded, leaf -like scale. The colour in life is pale yellowish 

 or greyish white ; sometimes the disc is speckled and the rays 

 variegated or banded with dark grey. 



Not uncommon near Wellington, among the roots of Lessonia 

 and Macroeystis. 



This species is very nearly allied to Amphiura constricta, 

 Lyman. It may be readily distinguished, however, from that 

 species by the size of the upper arm-plates, which extend across 

 nearly the width of the arm ; by the form of the radial shields, 

 which are much shorter ; and the shape of the mouth-plates.

This little species is abundant on the roots of seaweed in
