wood. Xt is probable that the fossil known as Eozoon cauadense, 

 from the Laurentian serpentine, is of a similar nature. 



Mr. H. Sidebottom contributed a valuable paper on "The 

 Lagenae of the South- West Pacific." Mr. A. Earland, F.R.M.S., 

 in introducing this paper, said it was a very lengthy and valuable 

 one, and the Club would be proud to include it in the Journal. 

 It is Part 2 of a paper published in the April 1912 issue of 

 the Journal. By the kindness of Mr. H. F. Angus, who arranged 

 an exhibition frame for the drawings, he was able to exhibit 

 some of Mr. Sidebottom s beautiful drawings. The majority of 

 the stations from which the specimens dealt with were derived 

 (if not all) lie within the region of the South Pacific known to 

 oceanographers as the " Aldrich Deep." This area lies to the 

 east of New Zealand, between 15 and 47, and covers about 

 613,000 square miles. Three soundings exceeding 5,000 

 fathoms have been recorded in this area by Commander Balfour 

 in H.M.S. "Penguin" in 1895. The deepest sounding yet 

 made, however, is one in the "Challenger" Deep, near Guam, 

 in the Ladrone Islands. This is 5,269 fathoms, nearly six miles. 

 The Aldrich Deep has the second deepest record, 5,155 fathoms. 

 None of the material discussed in this paper comes from the 

 deepest parts of the area. The depths given by Mr. Sidebottom 

 range between 328 fathoms and 4,278 fathoms, but the majority 

 are under 2,000 fathoms. No details are given of the nature 

 of the material from which the specimens were derived, and 

 possibly the information was not in the author's possession, as 

 the majority, at any rate, of the specimens had been picked out 

 by Mr. Thornhill prior to his death, when the type slides passed 

 into the hands of Mr. Sidebottom for classification and description. 

 It may, however, be fairly surmised that, owing to the distance 

 of the area from any land, none of the samples would be terri- 

 genous deposits, but would be true oceanic deposits. Globigerina 

 and Pteropod oozes in the lesser depths, passing into pure 

 Globigerina ooze, and, beyond the 2,000-fathom line, into Red 

 Clay. The presence of a varied and rich fauna of Lagenaa in 

 the deep water of the South Pacific has been recorded by the 

 " Challenger" Some of the stations of that ship lie within the 

 same area as the " Penguin " material worked by Mr. Sidebottom, 

 but the " Challenger " material was either very poor in specimens 

 compared with the "Penguin" or it was very incompletely
