remains. These latter consisted for the most part of detached 

 oogonia, in a few cases containing oospores. The vegetative remains 

 comprised a number of small fragments of stems and branchlets, and 

 a few stem-nodes. In no case was an oogonium found attached to 

 the branchlet, and as more than one kind of fruit was found in each 

 bed, it was not possible to identify the fruits with the vegetative 

 parts to which they belonged. The fruits of twelve species are 

 described and figured, ten being treated as new. Two of these are 

 referred to Tolypella, closel}" resembling those of living species of 

 that genus ; the rest, in the absence of sufficient evidence to determine 

 their generic position, are placed under the parent genus Cltara, 

 although the authors do not consider that they all belong to that 

 genus as now understood. The coronules and stalk-cells of the oogonia 

 are missing ; and from this fact and the improbability of the spiral- 

 cells when filled with protoplasm being 2)reserved in the clays and lime- 

 stones, the authors conclude that it is only oogonia, the spiral-cells of 

 which have become calcified, that are present as fossils in these deposits. 

 This would explain the absence of any remains of Nitella, the oogonia 

 of which do not form a lime-shell. Some of the "fruits " illustrated 

 resemble those of the living species, while others evidently belong to 

 extinct types. The three excellent plates are from photographs taken 

 by Mr. lleid. 



The Annals of the Bolus Herhariuni (vol. iii. pt. 2 ; December 

 1921) contains a description and figure of a new genus {Pagella) of 

 CrassulacecB, by Dr. Schonlund ; " Novitates Capenses," by Mrs. L. 

 Bolus and others, includes a revision of Bestio, to which many 

 species of Hypotcdna and Leptocarpus are reduced, by Mr. Pillans ; 

 "Notes on Acmadenia,'' by E. A. Dummer ; and an account of 

 *' The Tyson Collection of Marine Algae in the Bolus Herbarium " 

 by Dr. Ellen M. Delf, in the course of which the paper on Cape 

 AlgEB by *'Miss Barton " (Mrs. Gepp), published in this Journal for 

 1893 is referred to and quoted : there is also a biograph}^ with 

 portrait of William Tyson (1851-1920) whose herbarium (save for 

 the Algae) was acquired by the Cape Government in 1892. 



For some years before the War, in which he fell, G. L. Gatin 

 was engaged in an extensive work on the embryo and germination of 

 monocot^^ledons ; the work is being continued by his widow, who 

 publishes in the Annales des Sciences Naturelles (issued in November 

 last) a first instalment relating to the Aracece, in the course of which 

 Arum maculatum and A. italicum are considered : the paper is 

 accompanied by ten plates. In the same number Joseph Magrou 

 has a long paper, with nine plates, on Symbiosis and Tuberisation. 



The Gardeners'' Clironicle for Dec. 24 contains an interesting 

 biographical sketch by Sir David Menzies of Archibald Menzies 

 (1754-1842), illustrated by a portrait and a picture of his birthplace — 

 Stix House, Aberfeldy. It may be worth while to note that several 

 letters from Menzies ranging in date from 1784 to 1795, some of 

 which contain matter of interest, are included in the transcript of the 

 Banksian Correspondence preserved in the National Ilerl^arium.
