Centroceras Kutz. 



I have followed Howe, Mar. Alg. of Peru, in regarding this genus as distinct from 

 Ceramium. 



C. clavulatum (Ag.) Mont. 



Chile: Valparaiso, abundant on rocks near Playa Anclia, waslied by the surf 

 also at low tide (St. 41, 2. 9. 08). 



Distribution: Widely spread in warmer seas. 



Grateloupiaceae. 

 Grateloupia Ag. 



G. Cutleriae (Mont.) Kutz. Phycol. gener. p. 398, t. 77. 



F u e g i a : Slogget Bay, washed ashore (St. 47 b, 16. 3. 09, e). 



One incomplete frond, very long and narrow (73x3 cm), closely approaching 

 f. procera Howe, Mar. Alg. of Peru p. 166 t. 59. As the basal parts are missing, the 

 possibility remains that my specimen is a lobe of a large dissected frond of O. schizo- 

 phylla Kutz. This is perhaps not specifically distinct from O. Cutleriae, comp. Howe 

 1. c. p. 168. The former was reported from Fuegia by Ardissone, Alghe Terra d. Fuoco 

 p. 213, and he is inclined to unite it with G. Cutleriae. 



Distribution: Pacific coasts of America. 



Cryptonemia J. Ag. 



C. obovata J. Ag. Sp. Alg. III p. 681. 



Chiloé: Queilen, 6 m, sand and stones (St. 33, 30.7.08, $). 



The first record from Chile and not found on the Peruvian coast. The only notable 

 difference between my specimens and the type in Herb. Agardh is that the former 

 have a rather distinct, basal midrib, which seems to be wanting or at least more feebly 

 developed in the latter ( »stipitibus complanatis nervö f ere nullo conspicuo continuatis », 

 Agardh 1. c), but this difference may be due to the circumstance that Agardh had 

 dried material, while my specimens were preserved in alcohol. 



Distribution: W. coast of N. Amer., Chile. 



Hildenbrandiaceae. 

 Hildenbrandia Nardo 



H. Lecannellieri HARIOT. — KYLIN & SKOTTSB. p. 75.
