suggestions in regard to the classification of the Vertehrata. On 

 the principal element of the primary subdivisions of the class 

 mammalia first promulgated in this paper, Professor Owen has 

 recently remarked in our ' Journal,' " that he considers it as the 

 most important improvement in the classification of mammalia 

 which has been proposed since the establishment of the natural 

 character of the Implacental or Ovo-viviparous division." From 

 this time the Prince became a frequent visitor at the meetings of 

 the British Association for the Advancement of Science ; and so 

 strongly was he impressed with the advantages derived from such 

 meetings, that he laboured long and successfully in the founda- 

 tion of a similar Association in Italy, the first meeting of which 

 took place at Pisa, in 1839, where and at the subsequent meetings, 

 until 1847, he was constantly President of the Zoological Section, 

 to which he made many interesting communications. By the 

 death of his father in 1840, he succeeded to the title of Canino ; 

 and in 1844 he was elected a Corresponding Member of the 

 Academy of Sciences of the French Institute. He continued to 

 reside at Kome, occupying himself incessantly with zoological 

 subjects, until the political events of 1847 rekindled in Italy the 

 revolutionary spirit, when he threw himself ardently into the 

 Republican cause, and became President of the Itoman Constituent 

 Assembly, which position he retained until the Roman Republic 

 fell before the arms of France. Proscribed in Italy, he retired first 

 to England, but finally took up his residence at Paris, frequently, 

 however, visiting this country, especially with a view to the meet- 

 ings of the British Association. For some years past he had 

 suffered severely from swellings and ulceration of the legs, which 

 at last terminated in dropsy of the chest, of which he died, after 

 much suffering, at his house in the Rue de Lille, at Paris, on the 

 30th of July, 1857, in the 55th year of his age. By his wife 

 Zenaide, who died in 1854, he had twelve children, nine of whom 

 survive him. The number of his works and papers comprised 

 in the list of the ' Bibliographia Zoologiae ' of the Ray Society, 

 amounts to forty-nine ; but these extend no lower than 1842, and 

 consequently contain none of his later zoological writings. The 

 production of a complete "'Systema Avium " was the great object 

 of his ambition ; and at this he laboured indefatigably, notwith- 

 standing his sufferings, to the last hour of his life. The portions 

 relating to Insessores and Grallatores are already published, and 

 the remainder is left in MS. ready for publication. A special
