/. delicatula nov. f.: Pusilla, inferne simplex, moniliformis, dein serael pinnatim 

 ramosa; conceptacula saepius acuminata. — West Patagonia: Evangelistas 

 Islands, tide-pools in the Porphyra belt (St. 26, 26. 5. 08, ?). 



This form is little more than half as coarse as C. ofjicinalis or chilensis; it agrees 

 with the latter in the shape of the conceptacles. 



C. officinalis L. forma. 



C h i 1 o é : Punta Talcan, litoral (St. 29 B, 12. 7. 08); Huafo Island, Samuel Cove, 

 abundant (St. 31, 25. 7. 08). 



Another doubtful form, hardly separable from C. ofjicinalis. It is distinguished 

 by the great length of the lower primary pinnae, that reach to the top of the upper ones, 

 by the comparative scarcity of normal secondary pinnules and the abundance of long, 

 hair-like, curved branchlets, but similar forms have been reported from European waters. 



Distribution of C. officinalis: Arctic, N. and S. temp. seas.
