WALTfciii Gkorge EiUEWoOD, wlio died 0)1 21st September 1921, 

 was born in London on Ist February 1867, and studied at the 

 Koyal College of Science from 1883 until 1887. He was interested 

 in zoology, and from 1881 until 1917 he held a temporary appoint- 

 ment in the British Museum (Natural History). During most ot" 

 this period he was also lecturer on Biology in the St. Mary's 

 Hospital Medical School. He was especially skilful in making 

 anatomical preparations, and a very large proportion of those in 

 the central hall of the Museum are his work. While occupied 

 with the preparations lie availed himself of every opportunity for 

 original observation and u)ade many important contributions to 

 our knowledge of the anatomy of the A^ertebrata. His early 

 paper on the structure and developmejit of the hyobranchial 

 skeleton and larynx in Xcnoims and Pqia, published in the 

 Journal of the Linnean Society, vol. 26, was his thesis when he 

 received the degree of D.Sc. from the University of London in 

 1897. His later researches on the skull of certain Teleosteau 

 fishes, pul)liahed partly by the Linnean Society, partly by the 

 Zoological Society, were intended to be incorporated in a volume 

 on the osteology of fishes, which unfortunately he never com- 

 pleted. His last memoir, on the structure of the vertebrae of 

 sharks and rays, was an especially valuable w ork publistied in the 

 Philosophical Transactions of the Koyal Society in 1921. He 

 also publislied a memoir on the gills of lamellibraneh ^lollusca in 

 the Philosophical Transactions in 1903, and new observations on 

 Cephalodiscus in the Keport of the British Autai'ctic (Terra JSova) 

 Expedition in 1918. Dr. Ridewood was elected a Pellow of the 

 Linnean Society on the 2Md March, 1893, and served on the 

 Council from 1903-06 and 1910-14. [A. S. AV^]
