the peace of ornithological nomenclature. In his later writ¬ 
ings Blyth adhered loyally to the “ rules of nomenclature ” 
It will be a matter of regret if the works of so diligent a 
writer should be allowed to remain diffused,, as they are, through 
so many zoological journals—the more so as the works of 
our most laborious compilers omit all references to original 
descriptions, nor do they furnish any clew to where they are 
to be found, beyond the name of a species and its author. Is 
there not here a field of activity for some member of our 
Union ? who, by making even an index to the generic and 
specific names scattered through Blythes works, would not 
only honour a great ornithologist’s memory, but also, by 
saving hours of too often fruitless search to his fellow-workers, 
confer a great boon upon ornithological science generally. 
Jules Pierre Yerreaux was born on the 24th of August, 
1807. At the early age of twelve years he accompanied his 
uncle, the well-known “ naturaliste-voyageur/’ Delalande, to 
the Cape of Good Hope, where he remained for two years, 
assisting in preparing the collections which were ultimately 
sent to the Paris Museum. On his return to Paris he studied 
in the laboratories of that institution under G. Cuvier and 
Isidore St.-Hilaire. After the death of his uncle, Jules Yer¬ 
reaux started alone for the Cape of Good Hope in 1825, where, 
partly in company with Sir Andrew Smith, he worked for 
five years with such success that he had to send for his 
brother Edouard to help him to arrange and pack his large 
collections, and take charge of them to Paris, where, on their 
arrival, they were arranged for exhibition in the galleries of 
the Baron B. Delessert. 
In 1832 Jules Verreaux again summoned his brother to 
join him, and till 1837 they travelled together, making expe¬ 
ditions to the Philippine Islands and Cochin-China. In 1838, 
having amassed large collections, the brothers shipped their 
treasures on board the trading-vessel f Lucullus/ they them¬ 
selves embarking in another ship bound for France. Most 
unfortunately the f Lucullus 3 was totally lost; and the labours 
of several years, uninsured, perished with her. Undaunted
