16 Lake on west side of McMurdo Sound 



January 1909 ; coll. R. E. Priestley. This lake was close to the " Stranded 

 Moraines " and twenty-five miles from the camp at Cape Royds. Lat. 77 45' S. It 

 is said to be a large lake, but there were no data as to the temperature of the water 

 or how long clear of ice. Water swarming with red Rotifers. Yellowish snow on 

 shores, believed to be caused by Rotifers, but specimen lost. 



The main mass of the material consisted of Oscillatoria priestleyi, amongst which 

 were scattered trichomes of Phormidium autumnale and Oscillatoria deflexa. Also 

 two species of Chroococcus. Numerous diatoms occurred, of a very similar nature to 

 those found in the lakes of Ross Island.

On the western side of the Ross Sea. October 23, 1908 ; coll. Prof. T. W. E. 

 David. Lat. 75 40' S. Situated 120 miles from the camp at Cape Royds.

 gonium- stages.
