340 Appendix to the Proceedings 



For the subject of this notice I propose the name of Coryne 

 gravata. 



The Rev. T. Hincks informs me that he has seen a Coryne 

 with cylindrical medusoids resembling fig. 5, but he did not 

 observe its sexual character. 



II. Stauridia producta (Mihi). 



In the " Annales des Sciences Naturelles," 3d series, vol. iv., 

 p. 271, M. Dujardin remarks, " J'y vis une sorte de Syn- 

 coryne que j'ai nommee Stauridie a cause de ses quatre tenta- 

 cules disposes en croix ;" and he proceeds to describe the 

 structure of the animal, and its reproduction by means of free 

 medusoids, to which he gives the name of Cladoneme. 



Mr Gosse, also, in his " Devonshire Coast," has described 

 and beautifully figured the same animal, under the name of 

 Coryne stauridia, or " the slender Coryne." This zoophyte, 

 one of the polyps of which I have sketched at PI. XIX., fig. 6., is 

 remarkable, not so much on account of the cruciform disposi- 

 tion of its tentacles, as for the dissimilarity in character of 

 those members ; the upper row being capitate, as in the genus 

 Coryne, while the lower are filiform and pointed, as in Clava, 

 Cordylophora, &c. 



The dissimilar character of the tentacles, however, must re- 

 move the animal of Dujardin from the genus Coryne or Syn- 

 coryne, and place it in a new genus, which will rank inter- 

 mediately between Coryne and Cordylophora in the classifi- 

 cation of Johnston. For this genus I propose the name 

 s; Stauridia," derived from Dujardin's Stauridie, although 

 the construction of the word and its meaning are incorrect 

 (aravgog, crux, signifying a stake, of any shape, to which a 

 criminal was nailed.) 



The characters of the new genus are : — 

 Genus Stauridia. 



Polypary sheathed in a tubular corallum or polypidom 

 {branched, the apices of the branches) bearing polyps furnished 

 with two or more whorls of dissimilar tentacles, — the upper 

 whorl or ivhorls capitate, the lower whorl filiform, four in 

 number. Thread-cells very large, many-barbed. 



In the spring of 1857 I picked up, on the shore at Caroline
