688 THE MARatllS OF TWEEDDALE ON [NoV. 6, 



In the Table showing the geographical distribution of the Philip- 

 pine 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 griseutus. Parus elegans. 



Calliope camtschatkensis. Geopelia striata. 



Phylloscopus borealis (olim Turnix ocellata. 



. magnirostris). Hypotcenidia 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. c.) at 133'; but Mr. Sharpe has cor- 

 rectly pointed out that Cataguan, which I had treated as a 

 separate island, forms, in reality, part of the island of Luzon. 

 Puffimis leucom.elas, which I recorded from there, must be added 

 to the number of Luzon birds ; and to this Mr. Sharpe adds Zeoce- 

 phus rufus and Penelopides panini^, 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 1 37 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. Rhynchcea capensis. 



The exact total of known Luzon residents will therefore now amount 

 to 160. 



1. PrIONITURUS DISCURUS (2)^. 



[Monte Alban. a, S : iris brown ; bill lead-grey ; feet bluish 

 grey ; nails dark grey, b, S • iris chocolate-brown ; bill lead-grey ; 

 feet bluish grey ; claws dark grey.] 



A series of seven examples, S 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 pro- 

 longed for about half an inch, but the shafts are webbed.
