Cemetery, where, at the present time, there is nothing to 
indicate that this is the grave of a consummate artist. 
It is intended also to purchase a portrait of him, to 
be presented to the Zoological Society of London. The 
portrait, painted by Lance Calkin, was exhibited in the 
Royal Academy of 1890. 
By the kind permission of Mr. B. Healey, a small tablet 
will be fixed at the entrance to No. 2 Primrose Hill Studios, 
London, where he died. 
Joseph Wolf worked for thirty-two years for the Zoological 
Society of London, in whose Library is a large series of original 
water-colour drawings taken by him from animals living in 
the Society’s Menagerie, and the good results of his labour

resting-place, but also at the Studio where he worked, and 
in the Rooms of the Society of which he was a Fellow. 
Donations to the Fund may be paid to Mr. Robert J. 
Howard, Shear Bank, Lilford Road, Blackburn.

ceedings’ (see P.Z. 8.1907, p. 852). After referring to his 
previous contribution (published in the ‘ Proceedings’) on 
the Osteology of the Eurylemid and Tracheophone Passeres, 
he remarked that there seemed little room for doubt that 
the Diacromyodian and Oligomyodian Passeres must be 
regarded as divergent branches of a common stem. The 
latter suborder, according to his views, included the 
Tyranniformes, Phytotomide, and Pittidee, while the former 
embraced the remaining Passeres. 
In the present communication some fourteen Families 
were described, and these were divided into four groups—
