metrical distribution of this species is thus not known with certainty to exceed 
75—250 m. 
The statement of the occurrence of the species at Kerguelen and Heard Island 
(»Challenger» Echinoidea) is uncertain, being founded on incorrect determinations, 
partly at least, and must be left out of consideration until it has been definitely 
proved that this species is really found in the said material or is otherwise recorded 
from these regions. The occurrence of the species at New Zealand (Rev. of Echini, 
p. 124) is still more improbable. The statement is founded on specimens in the 
Smithsonian Institution. But there are no specimens from that locality there, at 
least now, only two specimens with »unknown locality», according to Professor Rath- 
BUN’s »Catalogue of the collection of Recent Echini in the U. S. National Museum» 
(Proc. U. S. Nat. Mus. 1886, p. 278), and Miss Rathbun, who has kindly made a 
renewed research on this matter for me, gives me the same communication. Thus 
this evidence for the occurrence of the species at New Zealand is not worth much. 
The species is further named by Mr. H. FarQUHAR in his paper »On the Echino- 
derm Fauna of New Zealand» (Proc. Linn. Soc. N. S. Wales 1898, p. 320), but no 
new evidence of its occurrence there is given; in his later »Notes on new Zealand 
Echinoderms» (Trans. New Zealand Inst. XXXIX, 1906, p. 130) he says that, though 
it might be expected to occur there »it is not known to New Zealand naturalists 
(and) it may be omitted for the present». — A definite statement of its occurrence 
at New Zealand is given by FlLHOL,* who reports to have dredged the species in 
considerable numbers in Cooks Strait and at Stewart Island; also at the Campbell Island 
some specimens were obtained. There is, however, scarcely any doubt that this state- 
ment rests on wrong identification; the fact that the species is stated to be common 
in Cook’s Strait decidedly points towards a confusion with Pseudechinus albocinctus. 
It would be very desirable to have these specimens reexamined, those from New Zea- 
land as well as those from the Campbell Island; the latter would perhaps give a 
valuable contribution towards the solution of the problem, whether the marine littoral 
fauna of the Campbell Island is more nearly related to that of New Zealand or that 
of the Antarctic Continent. (Cf. Die Echinoiden d. Deutschen Südpolar-Exped. p. 93). 
Unfortunately none of the specimens are in the collection of the Museum d’histoire 
naturelle in Paris, as I am informed by Professor JOUBIN, so the question must be 
left undecided. — Also from the littoral region of the Antarctic Continent » Echinus 
margaritaceus » is recorded, viz. by Prof. Bell in his papers on the Echinoderms 
of the »Southern Cross» (1902, p. 219) and of the »National Antarctic Expedition» 
(Natural History. IV. Zoology. Echinoderms, p. 6). As, however, in the first
