Corallina, but they seem to belong to a species of Clioreoueraa. 

 The Cheilosponoii nia.ritiiuiii Yeudo (1902a, p. 22, pi. 2, f. 18, 19, 

 pi. 6, f . 9) seems but a more strongly calcified state of this form, 

 such as we have collected at Monterey, California.

A dwarf form including the Corallina arhuscula and C. 

 pilulifera of Postels and Ruprecht. It forms a transition from 

 f . CJiilensis to the next, because in some cases there may be found 

 more than two branchlets springing from one joint. The cristate 

 joints prolonged into filiform prolongations are more or less 

 common on the plants examined. The Corallina pilulifera of 

 Kuetzing (1858, pi. 64, I) may prove to be a different species. 

 The Arthrocardia frondescens of Setcheil (1899, p. 595) was 

 based on a few fragments of the /. fiiiformis of Ruprecht and was 

 recognized later when more perfect material was disco verd among 

 the Greeley and Snodgrass collections.

This form is distinguished, as Yendo has pointed out (1902, 

 p. 712, under Corallina Va ncouveriensis) , hy having move tlmn 

 two branchlets springing from an articulus the rule, thus giving 

 the plants a distinct habit. This happens to some extent in the
