THE RECENT CRINOIDS OF AUSTRALIA— CLARK. 791 



This raagiiificent series shows that wlien adult this species 

 ordiiuirily possesses an arm length of 30 mm. to 35 mm., the cirri 

 being xv-xxx, 12-14, 7 mm. to 8 mm. long; occasionally larger 

 individuals occur, the largest having an arm length of 70 mm. 

 while one is bearing eggs which has arms only 20 mm. long. 



In colour the great majority (587) are dull greyish-yellow 

 tinged with brown, the cirri and the proximal portions of the 

 arms being lighter than the rest; fifty-two of them are a rather 

 dark brown or purple with light yellowish cirri and arm bases; 

 seven have each segment of the aims, pinnules, and cirri deep 

 purple in the centre, the borders being white, this giving them a 

 beautiful and striking " pepper and salt " appearance. 



This lot also included four Pentacrinoid young attached to 

 seaweeds. 



" Australia." — Twenty-eight specimens. 



Additional Australian Records. — Port Jackson, 0-5 fathoms; 

 Nelson's Bay, Port Stephens ; Port Phillip. 



RemarJcs. — It is probable that this is the species upon which 

 Wright's Kallispongia archeri was mainly founded, though no 

 definite assertion to that effect can be made. In 1882 Bell listed 

 this species with a so-called specific formula which he evidently 

 believed to be diagnostic, thus technically naming it ; two years 

 later, however, he chose a new name for it under which it appears 

 in the "Alert" Report, the original name having been sliifted to 

 a species whichhe at first had called " insignis.^' Bell described 

 Pi as shorter than P„, and so, when he received some additional 

 specimens from Port Phillip he failed to recognise his species, and 

 bestowed a third name upon it. Whitelegge, who was familar 

 with the animal in life, had discovered the error in Bell's descrip- 

 tion as given in the " Alert " Report, and rectified it just as Bell 

 himself discovered it and published a short note to that effect. 

 By a curious circumstance it happened that, though Whitelegge 

 was right in his statement in regard to this form. Bell was in 

 error; for the specimens upon which Bell had founded his Antedon 

 incoinmoda do not belong to this species at all, but are represen- 

 tatives of the species which has recently been called lacertosa. 



Whitelegge, in his list of the Crinoids of Port Jackson, says : — 

 "In the description of this species the first pinnules are said to 

 be the shortest ; this is incorrect, the first pinnules are the 

 longest. Very common in deep water, occasionally found under 

 stones; Taylor Bay ; Watson's Bay. The stalked or larval form 

 is often found attached to seaweeds. August-September." 



It is interesting to find that this species, like the European 

 Antedon, breeds in the early spring, apparently as early in the 

 season as the conditions will permit.
