SEA LILIES, STARFISHES, ETC. CLARK. 77 



■water four hundred fathoms or more in depth, while half a 

 dozen others are of doubtful authenticity. The " Endeavour" 

 collection contains three hundred specimens of twenty-six 

 species, of which five are new to science and three have not 

 previously been recorded from Austraha. There are several 

 other species, previously known from the Torres Strait region 

 which are now recorded for the first time from southern 

 Queensland or New South Wales. Undoubtedly the best 

 feature of the collection is the notable series of Astroconvs 

 australis, but all the Trichasterids and Gorgonocephahds are 

 of great interest. The complete absence of ten or a dozen 

 well-known Port Jackson brittle-stars is rather remarkable. 

 Of the one hundred and twenty-three Ophiurans now known 

 from Austraha, at least sixty are not known from elsewhere.

These specimens range in disk-diameter from 15 to 25 mm. 

 Several have the arms more or less distinctly banded, indicating 

 a diversity of colour in life similar to that shown by the West 

 Indian species, 0. flacirda. Fourteen specimens. 



Locs. — Twenty miles east-south-east of Tasman Head, 

 Tasmania, 80-85 fathoms. 



East of Maria Island, Tasmania, 78 fathoms.

Ophiobyrsa rudis, Lyman, Bull. Mus. Comp. Zool. Harvard, 

 v., 1878, p. 131. 



This is a good series of this relatively httle-known species, 

 but they exhibit little diversity. The disk-diameter ranges 

 from 9 to 27 mm. The colour is yellow-brown of diverse 

 shades, the arms often with narrow darker bands. Seven 

 specimens. 



Locs. — East of Maria Island, Tasmania, 78 fathoms.
