Ohs. — In Queensland, the impressions of a few higlily ornamented 
plates have been found in the Star Series of Corner Creek, and Gympie Series 
of the Eockhampton District, which are provisionally referred to this genus.^ 
Actinocrinus, sp. ind. 
PL XX, Pigs. 6 and 7. 
Ohs. — The late Prof, de Koninck descrilted an internal cruslied cast 
from Glen 'William, referring it to Miller’s Actinocrinus polydactylus'^ of the 
European Carboniferous Limestone. 
The only specimens that have come under my notice referahle to 
Actinocrinus are the subjects of PI. XX, Pigs. G and 7. The first of these 
(Fig. 6) is a portion of a calyx, an internal cast, showing the three iDasal plates 
and some of the primary radials, particularly a large heptagonal and con- 
tiguous hexagonal plate. The crushed example is in all probability the same 
species, and I believe them both to he identical with De Koninck’s A. poly- 
dactylus. Their identity, however, witli the European species of that name 
is, I think, very problematical, as all the specimens lack the higlily ornate 
plates of the latter. De Koninck’s figure and our Fig. 7 show no ridges on 
the plates at all ; although on our Fig. G four principal ridges are to he seen, hut 
the other plates are quite plain. Under these circumstances it is better, I 
believe, to leave the specific identification of these specimens an open question 
until others in abetter state of preservation throw further light on the subject. 
In addition to the plates described by De Koninck, Prof. F. McCoy 
had previously noted the occurrence of “ fragments of pelvic plates of this 
genus ” in the Dunvegan Shale.^
