ASTERINA GUNNII. 
Gray, 1840. Ann. Mag. Nat. Hist., vol. 6, p. 289. 
The occurrence of this species on the West Australian coast is 
quite to have been expected. All the specimens have six rays.

This is one of the notable starfishes in the collection, for its 
occurrence off West Australia is very interesting, even if not sur- 
prising. The present specimen is 168 mm. across, and thus some- 
what smaller than the specimen described by Muller and Troschel 
(1842) but larger than the one so finely figured by Koehler in his 
account (1910) of the shallow-water starfishes of the Indian 
Museum (PI. XX). The individual from West Australia is, in its 
dry condition, dull, deep cream-colour with not very numerous, 
well scattered small spots of deep purple on the upper surface. It 
is remarkable for having 16 rays instead of the typical number, 15.

lations of the abactinal skeleton. By an unusual typographical error in 
Hinds and Noble’s Classic Greek Dictionary, 1901, p. 102, I was led to 
write the word acrystata in naming a brittle star in 1911, Bull. U.S. Nat. 
Mus. No. 75, p. 145. Under the circumstances, the name given is obviously 
a typographical error and the brittle-star should be known as Amphiura 
arcystata.
