confined to that coast which she so long and so successfully explored, 

 and the treasures of which she has so greatly helped to make known. 



From the preceding it may be readily known by the absence of the 

 whorled ramuli, by the articulations being swollen dow^iwards as well as 

 upwards, and when in fruit, by the densely whorled involucres, whose 

 inner edge is often fringed from base to aj^ex by the tetraspores, one 

 being produced at the apex of each joint. The favellse, so far as we are 

 aware, are unknown, nor have we heard of an}^ other localities than those 

 given above, nor does the S23ecies seem as yet to be known anywhere 

 abroad. 



When carefully preserved, it is a very pretty species, and, like the 

 other allied species of the genus, is beaxitifully glossy. Like them also, 

 it should be spread out in salt water, and in order that the paper may 

 retain as little of the salt water as possible, to prevent it getting damp 

 afterwards, it may be dipped in fresh water first, and then the salt water 

 will remain only on the siirfixce, from which it can be mostly removed 

 by the blotting-paper. For Plymouth specimens of this we are indebted 

 to various obliging correspondents. Salcomlje specimens we have not 

 seen.
