THE RECENT CRINOIDS OF AUSTRALIA CLARK. 785 



the same locality, but the cirri are most extraordinary ; there 

 are about fifty of them ; at the base they resemble normal cirri, 

 but most of them rapidly taper to a fine point, being only about 

 7 mm. or 8 mm. long ; they appear as if they had all been simul- 

 taneously broken off and regenerated, though they are thicker at 

 the base than regenerated cirri ; a few, which are broken distally, 

 are rather longer than the majority, though much smaller than 

 usual ; the longest stump is i 5 mm. long, The colour of the 

 specimen is a uniform slightly pinkish white. The remaining 

 specimens offer no points of especial interest. 



Off Manning River, 22 fathoms. — Twenty-three very young 

 ten-armed specimens and twenty-six larger specimens. 



Off Broken Head, 28 fathoms. — Four specimens. 



Off Cape Three Points, 23-34 fathoms. — Fourteen specimens. 



Port Phillip. — One small specimen (see below). 



"Australia." — One specimen. 



No locality. — Twelve specimens. 



Additional Australian Records. — Port Stephens in 6-8 fathoms; 

 Sydney ; Pore Jackson, 30-35 fathoms ; near Sow and Pigs Reef, 

 Port Jackson ; Port Phillip. 



Remarks. — This species has hitherto alwajs been confused with 

 P. macronema, originally described by Miiller from King George 

 Sound, from which it is quite distinct. 



One of the figures given by Wright in illustrating Kallispongia 

 archeri, supposed by him to be a new sponge, probably represents 

 this form, but as the figure is said to represent a varietal form 

 no nomenclatural confusion can result. 



In 1888 Professor Bell described his Antedon wilsoni from Port 

 Phillip which, so far as I can see, is nothing but the young of 

 the present species, though it was adopted as valid two years 

 later by P. H. Carpenter. More recently Dr. H. L. Clark has 

 again described the young of this species, this time under the 

 name of Himerometra ptedophora. 



The specimens upon whicn Dr. Clark founded his Himerometra 

 pcedophora are obviously young, representing a stage just subse- 

 quent to the first appearance of Pg- The cirri are only just 

 beginning to become carinate toward the tip, and the distal 

 segments are as yet comparatively long. The sacculi are " abun- 

 dant and large, especially in distal pinnules " as in the adult, and 

 the disk already " shows many small calcareous plates, largest 

 and most conspicuous aiound the base of the anal tube." Side 

 and covering plates have not as yet made their appearance. 



A specimen from Port Phillip, Victoria, is certainly referable 

 to '■^Antedon wilsoni" and '■^Himerometra pcedophora^" and no
