CORALLINA. 223 



it has undoubtedly no specific affinity. The joints of the stem and 

 main branches are more distinctly wedge-shaped, and broader 

 in proportion to their diameter, often produced at the shoulders 

 into a spine or short process. They vary a good deal in their 

 lengths, the lowermost being shorter than their own diameter 

 while the superior are in general twice as long. The branches 

 are erect, prettily pinnated with the lateral shoots, the joints 

 of which are rather long, ovate-lanceolate or linear and pointed, 

 with many intermediate forms, but always compressed and 

 brought to a sharp edge usually on both sides, sometimes on 

 one only. Ellis' figure is truly excellent. 



The muscologist will trace a resemblance between this coral- 

 line and his favourite Dicranum byroides ; and we find a plea- 

 sure in remarking, that its form is reproduced in the Australa- 

 sian seas, where it is represented by the Cor. Cuvieri of La- 

 mouroux. The Cor. Turneri of the same naturalist, and from 

 the same distant shores, imitates very closely our Cor. elongata.
