Antennularia ramosa (Lamouroux). 



At Positions 1, 3, 7, 13, 14, 32 (dead), 43, 60. 



Depth, 40-50 fath. 



A colony at Position 1 carried several Scalpellum. The species was 

 not numerous at any point. 



Aglaophenia myriophyllum (Linnaeus). 



At Positions 11 (four), 14 (one), 32 (one), 33 (two), 37 (one), 40 



(one), 43 (two small), 46 (one), 56 (one), 60 (two), 62 (four), 



67 (one). 

 Depth, 40-50 fath. 

 Gonangia were borne on one colony at Position 60. 



Aglaophenia tubulifera (Hincks). 



At Position 60 ; several colonies on Diphasia jnniiata, one with 



gonangia. 

 Depth, 49 fath. 



Plumularia catharina, Johnston. 



At Positions 1, 3, 4, 31, 33, 37, 38, 43, 52, 56, 59, 60, 62, vii, 80. 



Depth, 40-51 fath. or over. 

 • Generally of small or very small size ; on tubes of Chactopterus and 

 Pallasia, and on ScalpeUum, Macropoclia, Hyas, Pecten, Cellaria, etc.; often 

 numerous, several colonies occurring at the same position ; plentiful at 

 Position 80. The creeping form described by Hincks (54) occurred 

 exclusively at Positions 4, 37, 38, 52, 56, 59, 60 ; bearing gonangia 

 at 37, 38, 52 ; and predominated over the branching form at 62 and 

 80. The branching form bore gonangia at Position 3. 



Plumularia echinulata, Lamarck. 



Small colonies at Positions 10, 31, 34. 



Depth, 40-42 fath. 



On a tube of Pallasia, on Pecten opercularis, and on Porclla, respec- 

 tively. I have been unable to distinguish these specimens from 

 Hincks' description of echinulata, despite the fact that he only records 

 it from shallow water, and that it has only hitherto been recorded at 

 Plymouth inside the breakwater, and in the Yealm Estuary. 



Plumularia frutescens (Ellis and Solander). 

 A fragment at Position 52, on Macrop)odia. 

 Depth, 43 fath.
