be questioned, however, how far their determinations may be 

 relied upon. Species of Enteromorpha are, as it is well known 

 to algologists, highly variable in their morphological characters 

 according to the circumstances of the habitat and hence the 

 specific determination based upon a scanty material leads some- 

 time to a dangerous result. Yet I have here to add one more 

 species of Enteromorpha to our flora, after studying the origi- 

 nal specimens in the Agardhian Herbarium at Lund. 



Our specimens have a close resemblance with those which 

 pass often under Ent. clathrata Roth, in various herbaria. In 

 the Agardhian Herbarium, Ent. prolifera J. Ag., beside the 

 differences in the cellular form and arrangement, may be macro- 

 scopically distinguished from that species by having notice- 

 able difference in size between the principal segment and the 

 proliferating ramulets.

We have to add another Californian member into our algal 

 flora. After comparing the specimens there is least doubt left 

 about the identity of the plants from both sides of the Pacific. 



It will be advisable to treat the plant in question in an 

 independent specific position. The difference between this plant 

 and Cb. clavata KuTZ. is so distinct and much greater than 

 the difference between the allied members which stand in specific
