South Patagonia: Skyring Water, Ventisqueros Sound, 15 m, mud with 

 shells (St. 21, 27. 4.08). Fuegia: Slogget Bay, in tidepools (St. 47, 16.3.09).

P. anisogona Hook. Fil. et Harv. — Kylin & Skottsb. p. 53. 



West Patagonia: Puerto Bueno, sand and stones, 1 — 3 m (St. 27, 3. 6. 08). 

 South Patagonia: Skyring Water, Ventisqueros Sound, 15 m, mud with shells 

 (St. 21, 27. 4. 08, ®), Falkland Islands: Danvin Harbour, litoral, on stones 

 with Adenocystis (St. 10, 16. 1. 08); Cape Pembroke, abundant in places, on rocks below 

 low-water mark and in pools (St. 3b, 7.11.07, $, ©). South Georgia: Cum- 

 berland Bay, Boiler Harbour, 5 m (St. 48, 20. 4. 09, ? ). 



My tetrasporic specimens from St, 3 ha ve the swollen joints of P. tenuistriata 

 Hook. Fil. et Harv., but the ramification of P. anisogona. The tufts become very in- 

 tricate by numerous hooked branches, and resemble the samples from South Georgia 

 in my collection of 1902, referred here with some doubt by Kylin. My specimens from 

 St. 48 are very like normal anisogona.
