Ohs. — Prof, do Koninck descril)cd a small calyx under the name of 
^ynhatliocrinus ogivalis^, from Purragood on the Paterson Piver. It Avonld 
a|Apear to he easily detected hy two folds or ridges ornamenting the radial 
plates. De Koninck speaks of the hasal plates as of one piece. They are, 
hoAVCA'er, three in niimher, the sutures being obliterated by anchylosis. On 
comparing his A. ogivalis with the British species, S. conicus, De Koninck 
speaks of the latter as “ la scule esp^ce du genre actuellement connue,” but 
this contrasts strangely ndth a previous statement, “ comme dans toutcs les 
especes de ce genre” {i.e. ol Synhathocrinns). As a matter of fact, Messrs. 
Wachsmutli and Springer enumerate^ no less than ten species which were 
known at the time Prof, de Koninck’s Work was Avritten. 
I have not personally met with S. ogivalis. The horizon from which 
it Avas obtained will be Avithin the Carboniferous.

Ohs. — We do not possess any certain evidence of the presence of 
members of this family in our Carboniferous or Permo-Carboniferous 
rocks. Prof. McCoy noticed some large columns in the Bca^ W. B. Clarke’s 
collection “apparently of CyatJiocrimis,'' from the limestone at Wagamec, 
and AVollamhoola.^

Ohs. — The presence of the type genus of this family is eAunced, 
according to the late Prof, de Koninck, by the occurrence of tAvo plates. One 
of these is a basal, and the other a radial. The former, says the describer, 
may belong to Foteriocrinus tenuis, MilleP, and the latter to F. radiatus, 
Austin®, “ or they may both belong to the same species.” The fragments come
