353 Obituary. 



list of the numerous Avorks of which the late Baron was 

 the author ; it must suffice to say that, commencing with 

 a catalogue of local birds and insects in 1831, he continued 

 to publish reviews, notices, and monographs, singly or in 

 collaboration with others, on Vertebrates of every description, 

 and on certain classes of insects. In particular, w^e may 

 mention his (Vertebrate) Fauna of Belgium, and an im-

 residence at Waddon House, near Croydon, where he

 the Gardeners' Company — honours bestowed upon him in 

 consequence of his devotion to pursuits specially connected 

 with those bodies — but he was also a Fellow of the Linnean, 

 Zoological, and Entomological Societies, besides being more 

 closely connected with us by his membership of our Union 

 and its offshoot the British Ornithologists' Club, of which 

 he was a Vice-Chairman. Mr. Crowley published very few 

 zoological papers, but devoted himself to the acquisition of 

 scarce specimens of butterflies and birds'-eggs with great
