Sally in the lower part, a coat of woolly, calcareous hairs. The radi¬ 
oles are generally slightly pinkish at the base. 
The secondary spines are flattened, straight, slightly t lc ene 
at the point; those on the aboral side are of a faint greemsh tmt. 
Figures of the pedicellariæ were given in my „Ingolf -bchtn- 
oidea 1, to which may be referred. lt is to be noticed that the 
large globiferous pedicellariæ, which are rather scarce in num er, 
are not placed on the naked, sunken part of the interambulacra, 
as they are in G. geranioides and tubaria, but at the edge o t e 
tuberculated part, close to the horizontal sutures. They are rat er 
unlike the peculiar globose pedicellariæ of the typical Gonicidans- 
species. The stalk is not very short; it has no limb. Tndentate 
pedicellariæ have not been observed. - The spicules of the tube- 
feet do not afford marked specific characters. One tubefoot was 
found to offer the curious anomaly of having a small sidebranch, 
ending in a small disk like the main stem of the foot. 
In his „Endeavour" Echinoderms (p. 104) H. L. Clark suggests 
that the Cidarid from Tasmania which he refers to Gomocid. cly- 
neata Dod. may perhaps be identical wi.h G. umbraculum. Dr. Ch. 
Anderson, director of the Australian Museum, Sydney, having 
kindly sent me two specimens of the Tasmanian species I can 
positively assert that it is not identical with G. umbraculum. It is 
a much more delicate form, very closely resembling the Japanese 
G. clypeata, as stated by Clark. Whether it is really identical with 
that species 1 shall not try to decide here; also I must refrain at 
the present occasion from a discussion of the proper limits of the 
difficult genus Goniocidaris.

This species, which was discovered by the New Zealand Gover- 
ment Trawling Expedition (the „Nora Niven“ Expedition) was re¬ 
ferred by Ben ham to Porocidaris elegans Agass. Professor Ben¬ 
ham having kindly sent me two specimens of the species, thus 
affording me the opportunity of examining it, I must assert that it
