In the present species we have a plant to which the same name 

 was given at about the same time by two different authorities. 

 Harvey gave the name Gigarfina muricata to a foi-m from San 

 Francisco in 1839 or early in 1840 as far as dates may lie settled 

 with any certainty, while Postels and Ruprecht gave the same 

 name to a form of the same species in 1840. It has seemed best 

 to us to take the ])lant of Harvey as the f. fijpica and to consider 

 San Francisco as the type locality. This plant is well described 

 by Harvey in the Nereis Boreali-Americana (1852, ]). 182. ])1. 

 27, B). It is more or less irregularly branched, cylindrical, and 

 beset with spines which are simple or slightly bifid. The speci- 

 mens quoted above, so far as we have seen them or so far as they 

 are described, seem to belong to the typical form as described l)y 

 Harvey and as we have found it in the neighborhood of San 

 Francisco. The P. hannilosfi (Ruprecht) J. Agardh seems to 

 dilfer fi-oni P. nno'icata onl\ in having the cystocarps at the 

 bases of the ramuli, while in the latter species the^' are simply 

 lateral. We have found lioth sorts on the same ])lant, so it has 

 seemed best to include both under the older name. Harvey 

 states that Ruprecht's Acantlaxladia muricata is more slendei- 

 and less regulai-ly nuiricated than his E. marie (fa and that 

 Ruprecht's .1. Iiamiilosa is identical with his P. muricata {lor. 

 cit., p. 183).
