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 Gigartina muricata to a form from San 

 Francisco in 1839 or early in 1840 as far as dates may be 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 plant of Harvey as the f . typica and to consider 

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

 by Harvey in the Nereis Boreali-Americana (1852, p. 182, pi. 

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

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

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

 are described, seem to belong to the typical form as described by 

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

 Francisco. The E. hamulosa (Ruprecht) J. Agardh seems to 

 differ from E. muricata only in having the cystocarps at the 

 liases of the ramuli, while in the latter species they are simply 

 lateral. We have found both sorts on the same plant, so it has 

 seemed best to include both under the older name. Harvey 

 states that Ruprecht's Acanthocladia muricata is more slender 

 and less regularly muricated than his E. muricata and that 

 Ruprecht's .1. hamulosa is identical with his E. muricata (loc. 

 cit., p. 183).
