the class Insecta to the Encyclopcedia Britannica, and was 

 also connected with the Field newspaper as one of the 

 Natural History editors, and sole editor for Travel. In 

 1874, Mr. Rye was appointed Librarian of the Royal Geo- 

 graphical Society, and from this date his numerous literary 

 engagements caused him to withdraw his attention from 

 entomological field work. His splendid collection of coleop- 

 tera is in the possession of Dr. Mason, of Burton-on-Trent, 

 by whom it was purchased a few years ago. 



Dr. GWYN Jkffrys was born in January, 1809, and died 

 January 24th, 1885, aged 'j6. He practised as a solicitor at 

 Swansea until 1856, when he was called to the bar. Shortly 

 afterwards he retired from the profession, and devoted him- 

 self to the study of Natural History, a taste for which he had 

 acquired as a boy when he took great interest in the insects 

 and shells occurring in South Wales. He appears to have 

 made Conchology his principal study, and as an autliority 

 soon ro.-e to fame. Among his most important literary 

 works is British Conchology in five volumes. He was an 

 honorary LL.D. of St. Andrews, and a Fellow of the Linnean 

 and Royal Societies. 



Henry Milne-Edwards was born of English parents at 

 Bruges, in October 1800, and died in Paris, July 29th, 1885. 

 His name will always occupy a prominent place among the 

 most eminent naturalists of the first half of the present 

 century. Although he at first took up the practice of medi- 

 cine as a profession, he eventually abandoned this in favour 

 of Natural History, in the study of which he had always 

 evinced a passionate interest. The lower forms of animal 

 life principally engaged his attention, particularly the Marine 

 Invertebrata, and it is among these that he found material for 

 much original research. 



His earliest important investigations were undertaken 

 during the year 1 826 and 1828, when he and Audouin studied 

 the littoral zone fauna of the coasts of Granville and around 

 the Isles of Chansey to Cape Frehel. In 1829, the results of 

 their labours were brought before the French Academy of 

 Sciences, and in I830, Cuvier, assisted by Dumeril and 

 Latrielle, drew up and presented to the Academy a report
