Peachia ctlindrica (Reid). 



In the Annals of N. H. for January, 1848, Dr. Eeid 

 described and figured, under the name of Actinia cylindrica, 

 an Actinoid, which was washed ashore at St. Andrews. 

 It must have certainly been a Peachia, and may possibly 

 have been an immature P. hastata. The points in which 

 it disagreed with such specimens of the latter as I have 

 seen were the following: — 1. It was but one and a quarter 

 inch long. 2. The conchular lobes were twelve, six of 

 which were very minute ; triangular, orange, with trans- 

 lucent edges. 3. Twelve bands of faint reddish-brown 

 radiated across the disk.
