CORTMORPHA. 119 



I have a specimen of it from Lady Keith Murray, foiinri 

 by her near Stonehaven. This species is about three inches 

 in height, the tubes slender, of a pale colour, and horny. 

 "When the polypes are all displayed, they afford a very 

 interesting spectacle, equalled by no other species I have 

 seen; the crimson heads contrasting finely with their white 

 polypidoms, especially when loaded with the reproductive 

 bulbules, which pullulate from the inner side of the bases of 

 the inferior tentacula.'^ {Dr. Johnston.) — Mr. Harvey found 

 his specimens at the steam-bridge on the river Dart, in 

 clusters on the links of the chain, and also on the links 

 over which the floating bridge at Devonport runs. 



' Genus VII. COEYMORPHA, Sars. 



1. CORYMOIIPHA NUTANS. 



Hab. Orkney, Porbes and Goodsir. 



Por the generic and specific characters we must refer to 

 Dr. Johnston''s work, pp. 54^ and 55, and to his characteristic 

 figure, plate vii. fig. 4. 



" We found the CorT/morpha in ten-fathom water in the 

 Bay of Stromness, Orkney. When placed in a vessel of 

 sea-water, it presented the appearance of a beautiful flower.
