Fakquhar. — Notes on Neiv Zealand Echinodcrms. 129 



between the extinct DinornithidcE of New Zealand and the ex- 

 tinct /Epiornithidce of Madagascar. Our fern-bird belongs to a 

 genus {Sphenopacus) found only in New Zealand and South 

 Africa, with a near relation in Madagascar ; and the beetle 

 Sternaulax and the marine shell Littorina mauritiana occur in 

 New Zealand and Madagascar, the latter being also found in 

 Australia. (See Introduction to the Index Faunae N.Z., p. 6.) 



Centrostephanus rodgersii. 

 Strongylocentrotus erythrogrammus. 



New Zealand specimens ol both these species are in the 

 Colonial Museum at Wellington, as noted by me in the Linnean 

 Society's Journal (ZooL), vol. xxvi, p. 189. These are omitted 

 from the " Index," although Strongylocentrotus tuherculatus, 

 which is noted as a New Zealand form on the same page, is re- 

 tained. C. rodgersii ranges from New Caledonia to Tasmania 

 and New Zealand, and S. erytjirogrammus occupies the same 

 area, wdth extensions to Japan and Chili. *S. tuherculatus was 

 found at the Kermadecs by Mr. Haylock. 



Sphaerechinus australe. 



This species, which is given in my " List " and omitted from 

 the " Index," occurs in Australia, Tasmania. Mauritius, and the 

 Society Islands. It is recorded by Agassiz as from New Zea- 

 land, and is one which we might expect to find here ; as, however, 

 it is not known to New Zealand naturalists, it may be omitted 

 from our list, at any rate for the present. 



Holopneustes inflatus. 



I gave this species in my " List " on the authority of Mr. 

 Agassiz (Rev. Ech., pp. 136, 483 ; and Chger. Repts., iii, p. 274), 

 but as it is not known here it may be correctly omitted from the 

 " Index." Dr. Ramsay says, " Three species — H. inflatus, H. 

 forosissimus, and H. purpurescens — are somewhat doubtfullv 

 recognised by Agassiz, and without a large series of specimens 

 it is almost impossible to distinguish the varieties : it is quite 

 likely that they all belong to one species. As Holopneustes 

 occurs on the east and south coasts of Australia, it is not unlikelv 

 to occur in our seas. Some clredging operations have recentlv. 

 I believe, been carried on in the neighbourhood of Dunedin. and 

 some of the species now omitted from our list may have been 

 rediscovered, but I do not know what echinoderms were ob- 

 tained.
