4. P. plumbeitarsus has a stouter bill, and, as a rule, 
shorter. This is conclusive. 
_ 5. P. plumbeitarsus differs in colour, and is a darker-toned 
bird, especially the head. 
6. P.viridanus abounds in India, but P. plumbeitarsus has 
not yet been procured in India! It is, however, abundant in 
Burmah, where P. viridanus isnot common. ‘This latter con- 
sideration quite settles the question in favour of distinctness, 
even had there not been those of structure and plumage so 
well marked. Some day or other, I expect, we shall hear of 
P. plumbeitarsus having a very distinct voice. As yet its 
voice has not been described.c~W. Epwin Brooks. 
Garrod Memorial.—The friends of the late Professor Alfred 
Henry Garrod, F.R.S., being desirous of possessing some 
memorial of him, it has been agreed, after due consideration, 
that this object will be best effected by the republication in 
a collected form of all his separate memoirs and papers, both 
zoological and physiological, prefaced by a biographical notice 
and portrait of the author. A Committee has been formed to 
carry out this object, consisting of :—Prof. W. H. Flower, 
eee SS. se. lei sclater; Hsqi bh. Dev Ran. Ses) ddr Ac 
Gunther, F.R.S.; O. Salvin, Esq., F.R.S.; F. M. Balfour, 
Esq., F.R.S.; Prof. E. A. Schafer, F.R.S.; G. E. Dobson, 
Esq.; E. R. Alston, Esq.; Prof. F. Jeffrey Bell; W. A. 
Forbes, Esq., Secretary. 
It is estimated that Professor Garrod’s collected papers will 
form a volume of about 500 pages, royal octavo, illustrated 
by 25 plates and numerous woodcuts. 
Each Subscriber to the Fund will be entitled to receive a 
copy of the work for every guinea subscribed. 
Intending Subscribers are requested to forward their names,
