It will be seen that a very considerable proportion of these deep-water 

 species are endemic ; the others are Indo-Pacific. As Mr. Farquhar has 

 already pointed out, the littoral fauna is not at all related to that of New 

 Zealand, but is distinctly Indo-Pacific, with much affinity to the east Aus- 

 tralian coastal fauna. 



I have not thought it necessary to repeat the synonymy or the references 

 to the earlier literatu e ; both of these matters may be found treated at 

 length in Farquhar's paper (1898). 



Asteroidea. 

 Astropecten polyacanthus Miiller and Troschel. 



One specimen dredged in 12 fathoms, on gravel bottom, west of Meyer 

 Island (20/4/1908), and a second smaller one dredged in 20 fathoms in 

 Denham Bay, Sunday Island (4/4/08). 



The larger individual has the following dimensions : R 87 mm., r 15 mm. : 

 so that R : r = 5t. One ray is quite short and stumpy, being in the course 

 of regeneration ; of the original arm only 23 mm. remains, while the new 

 tip is 12 mm. in length. 



A small specimen, in which R 10, r 4, appears to be the young of this. 

 It is, however, almost too small to be worth describing in detail. There is 

 a single spine on each of the supra-marginals, but the infra-marginals carry 

 only 2 spines in place of the 4 or 5 of the adult. 



This is a widely distributed species, not hitherto recorded from the 

 Kermadecs. It is said by Hutton (1872, p. 6) to occur on the New 

 Zealand coast, but I have not seen a specimen. 



Distribution. — Red Sea, Indian Ocean (Mauritius, Ceylon, India, 

 Andamans), Pacific (Australia, China, Japan, Fiji, &c.).

I have before me, including the type, three stages in the growth of this 

 species, which in some respects seems partly to bridge over the gap between
