 secured the services of Mr. George West, jun., by whom all the species figured, from 

 the series referred to, have been drawn. 



In 1882 a fresh collection of specimens of Alcyonaria was sent from Edinburgh ; this 

 collection, packed in six boxes, reached Dublin in July 1882. Five of these boxes con- 

 tained tin cases, in which were found an immense assortment of forms which had been 

 placed in strong spirits, just as they had been taken from the dredge. One box was

 rare species not found in the first series. Among others may be mentioned the remarkable
