entangled, and less green than the other. The long 

 slender branches looked like a filmy cloud in the water, 

 but made a beautiful object on paper. The greener one 

 we fancied was E. siliculosus, but as the lens revealed 

 none of the pod-like fruit, we could not be sure whether 

 it was that species or the E. litoralis {Plate II, Jig. 11.) 

 Fortunately Dr. Landsborough gives an ordeal by which 

 these closely allied sjDecies may be distinguished, not 

 that of fire, nor of red hot ploughshares, but of boiling 

 water, a plunge into which turns the E. litoralis bright 

 green. Thus we decided that the coarser plant was the 

 E. litoralis, and the frail elegant olive green branches 

 were E. siliculosus. There are many other species in 

 this family, some with more simple branches, paler and of 

 smaller size, but we were content with our representatives 

 for a beginning. Of the Myriotrichias, with their densely 

 crowded branched hairs, we did not meet with a single 

 specimen, they both are mere parasites, living on Chorda, 

 and are but a few lines in size.
