S8 DISCOVERY REPORTS 



A single very fine and perfect specimen, sessile on a zoophyte fragment, was found at 

 St. i8i in the Palmer Archipelago, depth 160-335 m. At St. 177 in the Bransfield 

 Strait, depth 1080 m., two large fragments representing the columnar portion of the 

 organism were observed. At the same station, sessile on a pebble, was a flat outspread 

 growth, white in colour like other sessile organisms at this station, which may represent 

 the basal pad. It has a large circular opening near the edge from which the outstanding 

 column may have been broken. The variety was originally described from 160 to 300 

 fathoms in McMurdo Sound, in the Ross Sea sector of the Antarctic.

One station: 386. 



A few fragments, apparently the tubular portion, were found outside the Antarctic 

 convergence at St. 386 in the Drake Strait, depth 4773 m. The variety was originally 

 described from comparatively shallow water (180-200 fathoms) off Oates Land in the 

 Ross Sea sector of the Antarctic. 



67. Dendronina papillata (Heron-Allen and Earland) (F 59) (SG 50). 

 Five stations: 170, 177, 181, 182, 195. 



Specimens in all stages of development are not uncommon on pebbles at St. 177 in 

 the Bransfield Strait, depth 1080 m. Otherwise the species is represented at the re- 

 maining stations only by single specimens in the earliest stage of growth.

Two stations: 170, 175. 



No specimens of P. jeffreysii were found in any of the soundings or dredgings, but a 

 few very large specimens picked out of the sieves on board ship were received in spirit. 

 St. 170 is off Clarence Island, about midway between the South Orkneys and South 

 Shetlands, depth 342 m. St. 175 is in the middle of the Bransfield Strait, depth 200 m. 

 It seems likely that the species may be widely distributed in the area, but the chance of 

 securing such a large and fragile organism in the sounding tube is very small. Some of 

 the specimens are as much as 7-0 mm. in diameter, which is twice the size recorded by 

 Brady. The construction is particularly neat, the acerate spicules of which the test is 

 largely composed being felted together very closely. The specimens which I have 

 dredged off the west coast of Scotland are less neatly compacted. 



An abnormal specimen was received from St. 175. It is 12 mm. long and 5 mm. 

 broad, sausage-shaped and slightly collapsed. There is a characteristic aperture at each
