64 NATURAL SCIENCE. July, 1896. 



the Naples Zoological Station. In 1893 h^ returned to England, first 

 to work in the Biological Laboratory of University College, London, 

 and then becoming Berkeley Fellow of the Owens College, Man- 

 chester. His original researches dealt mainly with the anatomy and 

 development of fishes, and he arrived at very heterodox views on 

 certain morphological questions. His first memoir, on the anatomy 

 and phylogenetic position of PolypUnis (Zool. Jahvhucher, 1892), 

 advocated the close affinity of this fish with the ancestry of the 

 Amphibia. In his next memoir [op. cit., 1895) he considered that the 

 tentacles of the higher fishes were homologous with the oral cirri of 

 Aviphioxiis. He also investigated the " lateral line " system of the 

 Siluroids, and made many observations on the development of the 

 suspensory apparatus of the jaw in some of the higher bony fishes. 



The Rt. Hon. Thomas Lyttleton Powys, fourth Lord Lilford, 

 died on Wednesday, June 17, aged 63. He was president of the 

 British Ornithologists' Union, and, at Lilford Hall, near Oundle, in 

 Northamptonshire, he had a remarkably fine collection of birds, both 

 alive and dead. It is not long since his work on the birds of his own 

 county was published. British ornithologists will regret the loss of so 

 prominent a colleague. 



We regret to learn of the death of Mr. H, C. Levinge, of 

 Mullingar, Ireland. At one time an enthusiastic collector of Indian 

 ferns, he afterwards gave himself up to the study of the Irish flora, to 

 which he added several species. Mr. Levinge will be greatly missed 

 by the many botanists to whom he extended his hospitality and his 

 help. 



The well-known professor of zoology and anthropology at 

 Moscow, Anatoly Bogdanoff, died last April, at the age of 62. He 

 was the author of a " Chrestomathy of Zoology," the founder of the 

 " Society of Lovers of Natural Sciences," and editor of the valuable 

 publication " Materials for the History of Zoology." 



We have also to record the deaths of: on May 21, in Bohemia, 

 Carl M. Balling, a distinguished metallurgist, and writer of a number 

 of treatises ; on January 14, at Brussels, Antoine Duvivier, a 

 distinguished student of Coleoptera ; Dr. Hermann Stieda, assistant 

 in clinical surgery at the University of Tubingen, aged 28 ; on 

 February 11, at Chestnut Hill, Mass., Dr. D. D. Slade, lecturer on 

 comparative osteology at Harvard University, aged 71 ; General 

 T. L. Casey, a well-known coleopterologist, in Washington, on 

 March 25 ; H. E. Bauer, an authority on Brazilian geology, in 

 Xiririca, on February 21 ; Rev. H. Waller, an ardent researcher 

 among African flora, in Northamptonshire, on February 22; J.Flohr, 

 a collector of Mexican Coleoptera, in Vera Cruz.
