72 Mr. R. Kirkpntrick on the 



Spongodes JlahelNfera , n. sp. 



The colony forms .in upright stem, 73 milHm. high, from 

 which, at a height of 30 millim. and u])wards, branches come off 

 on all sides. Tliese speedily ramifying form at the end small 

 umbels, in which each terminal twig bears a bundle of from 

 three to eight polyps ; but here and there also single polyps 

 occur. The lowermost branches are flat and their twigs are 

 fused together ; they thus form fan-shaped serrated folia, the 

 margins of which are beset with rows of polyps. The ramifi- 

 cation is loose, so that it can easily be made out everywhere. 

 The polyp-heads are pedunculate, free from one another for 

 a short space, and slightly surmounted by bundles of spicules. 

 The heads are surrounded by eight groups of spicules arranged 

 en chevron y which project like teeth above the margin.

After a comparison of the tyiiical specimen of Spongodes 

 rawnhsa, Klunzinger, which Professor von Martens most 

 kindly lent me from the Berlin Museum, with specimens 

 of Gray's species, it became evident that the two are speci- 

 fically distinct. Hence the name S. Klunzingeri might be 

 adopted for the species from the Red Sea described by 

 Klunzinger.
