Notes and Comments. 
BLAKENEY POINT. 
The National Trust has issued an interesting report on 
Blakeney Point in 1913. which deals with the work of the 
Committee of Management and of the Laboratory. There are 
valuable notes in reference to the local protection of bird life, 
vegetation, mammals, etc. In many ways Blakeney Point 
seems to resemble Spurn, and the view of the Terns’ Breeding 
Laboratory at Blakeney Point. 
Ground, which we are permitted to reproduce, might very 
well stand for a photograph of Spurn Head. 
HYPOCRINUS. 
In the Proceedings of the Zoological Society Dr. F. A. Bather 
has recently published an interesting note on ‘ The Fossil 
Crinoids referred to Hypocrinns Beyrich.’ These are based 
on a Crinoid Cup from the Carboniferous Rocks of Yorkshire, 
elsewhere described as Sycocrinus parvulus, though certain 
features suggested a comparison with Hypocrinns schneideri. 
The two specimens of Hypocrinns schneideri Beyr. described by 
Beyrich and Rothpletz respectively, are redescribed and re- 
figured. The structure of the genus is shown to agree with that 
of the Devonian family Gasterocomidce, but it is suggested that 
in this case and in that of ‘ Lecythiocrinus ’ adamsi the dis- 
tinctive features may have been independently acquired. 
The holotype of ‘ Hypocrinns ’ piriformis Rothpletz is re- 
described and refigured, and proved to be no Hypocrinns. It 
is thought to be a highly modified descendant of the Taxo- 
crinidae, by way of such a genus as Cydonocrinus. The left 
posterior radial appears to have borne a large arm, but the
