SEA LILIES, STARFISHES, ETC. — CXAKK. 89 



resiliens in its general appearance and I at first thought it to 

 be an Ophiolebes, but the mouth parts seem to be undoubtedly 

 those of an Ophiactis and I therefore have referred it to this 

 genus without dissection. The oral surface is rather markedly 

 like Ophiactis abyssicola but the disk-covering is utterly unhke 

 that species, and is indeed the distinguishing specific character. 

 The short arms, few stout arm-spines and pair of oral papillae 

 are additional features worthy of emphasis. 



Loc. — East of Fhnders Island, Bass Strait, 100-300 fathoms.

These specimens are all smaller than Lyman's type and as 

 a rule have only 4 or 5 arm spines, but on a few basal arm 

 joints of the largest specimen (disk diameter, 4 mm.) there 

 are 6 spines. The type locality was Port Jackson, New 

 South Wales, and there is a specimen in the Museum of Com- 

 parative Zoology from Westernport, Victoria. The " Endea- 

 vour " specimens thus extend the known range considerably 

 to the westward. Three specimens. 



Locs. — Forty miles west of Kingston, South Australia, 30 

 fathoms. 



Off Cape Martin, South Australia, 21 fathoms.

These specimens range from 5 to 18 mm. in disk-diameter 

 and make a fine series of this handsome Brittle-star. The 

 colour ranges from nearly white to rosy pink; the spines are 

 always white or colourless Two of the large individuals are 

 beautifully though sparsely spotted with bright brown. 

 There is a broad longitudinal stripe on the upper side of the 

 arms, in one large specimen deep pink, but usually pure white. 

 Jt seems to be lacking in the specimen from Oyster Bay,
