Show 688 THE MARQUIS OF TWEEDDALE ON [Nov. 6, In the Table showing the geographical distribution of the Philippine birds (t. c. pp. 249, 252) I enumerated 57 the exact habitat of which had not been established. From this, one species (the so-called Crateropus caudatus) must be deducted. Mr. Sharpe has been able most satisfactorily to reduce the number by 8 (t. c. p. 308) ; and Mr. Everett's discoveries enable me to still further diminish the number by 9. Philippine species of which the exact habitat has been determined by Mr. Everett:- Caprimulgus griseatus. Parus elegans. Calliope camtschatkensis. Geopelia striata. Phylloscopus borealis (olim Turnix ocellata. magnirostris). Hypoteenidia philippensis. Orthotomus derbianus. Ardetta cinnamomea. So the precise habitats of only 39 species now remain undetermined. The total number of species known to be resident in the island of Luzon I estimated (t. ci) at 133 **; but Mr. Sharpe has correctly pointed out that Cataguan, which I had treated as a separate island, forms, in reality, part of the island of Luzon. Puffinus leucomelas, which I recorded from there, must be added to the number of Luzon birds; and to this Mr. Sharpe adds Zeocephus rufus and Penelopides panini2, obtained by Mr. Cuming at Cataguan, and Erythropitta erythrogastra, on the faith of a Manilla example so labelled in Mr. Gould's collection. To this amended total of 137 Luzon species Mr. Everett has enabled me to add the 9 species already removed above from the general Philippine list, the 3 undescribed species and the 3 other species new to the fauna above mentioned, besides the following 8 residents of other Philippine islands:- Eudynamis mindanensis. Copsychus mindanensis. Lanius nasutus. Corydalla lugubris. Lalage dominica. Arachnechthra jugularis. Hirundo gutturalis. Rhyncheea capensis. The exact total of known Luzon residents will therefore now amount to 160. 1. PRIONITURUS DISCURUS (2)3. [Monte Alban. a, 6": iris brown; bill lead-grey; feet bluish grey; nails dark grey, b, $ : iris chocolate-brown ; bill lead-grey; feet bluish grey ; claws dark grey.] A series of seven examples, cS and shot in February, is sent by Mr. Everett, all being in bright green plumage without a trace of blue on the head. The elongated naked shafts of the middle pair of rectrices greatly vary in length, some being only half an inch, others two inches in length. In two examples these feathers are prolonged for about half an inch, but the shafts are webbed. I £0nf' SharPe' t- c- P- 309- a Is it "ot P. manillce?
