Echinus margaritaceus. 

 Peronella rostrata. 

 Metalia sternalis. 



These three species are omitted from the " Index." I in- 

 cluded them in my "List" on Mr. Agassiz's authority (Chger. 

 Repts., iii, pp. 274, 275). Echinus margaritaceus \?, widely spread 

 in southern seas, having been found at the Straits of Magellan, 

 Juan Fernandez, Kerguelen Land, and Heard Island, and we 

 may expect to find it in our southern waters ; but as it is not 

 known to New Zealand naturalists it may be omitted for the 

 present: Peronella rostrata is a Zanzibar form which does not 

 occur here. We have a species of Peronella, however, specimens 

 of which are in the Otago Museum, from the West Coast Sounds. 

 Two species of Peronella occur in Australian waters, P. decagonale 

 and P. feronii. The former appears to be confined to the Indo- 

 Pacific region, and the latter ranges from the Philippine Islands 

 to Tasmania. Being unacquainted with these, I cannot identify 

 our species. Metalia sternalis is a tropical form, widely diffused 

 in the Indo-Pacific region, and does not, I think, occur in our 

 seas. 



Brissopsis luzonica. 



I do not know of the occurrence of this species here. It is a 

 tropical form, widely spread in the Indo-Pacific region, and I 

 do not think it belongs to our fauna. It is given in the " Index." 

 although I marked it " doubtful " in my " List " for both New- 

 Zealand and Australia. 



Salmacis. 



We have a species of Salmacis in New Zealand, but I do not 

 think it is S. globator, which is given in my " List " and in the 

 " Index." Specimens are in the Otago Museum from Stewart 

 Island, and one denuded test is in the Colonial Museum. I be- 

 lieve it belongs to Bell's S. alexandri (" Alert" Report, p. 118), 

 which is a verv variable form, and occurs freely in Port Jackson 

 (Catl. Ech. Aust. Mus. (1891), p. 50). 



Phyllacanthus dubia. 



A specimen of Phyllacanthus, which I take to be P. dubia, 

 was found by Mr. Haylock at the Kermadec Islands. This is 

 an Indo-Pacific species, having been found also in New Cale- 

 donia, North AustraUa, the Red Sea, Zanzibar, and the Bonin 

 Islands.
