8. Graucalus hypoleucus louisiadensis subsp. uov. 



The material in the Tring Museum is uot sufficient to discuss thoroughly the 

 group o{ Gi-fn/cal'is lii/polencus, but there is, I think, no doubt that the birds from 

 Sndest Island retinire a snbspecific name. Their characters are : — Bill very large, 

 exposed part of cnlnieii 23 — 24 mm., niandiMc from end of fcatliering to tij) (gonys) 

 17 — I'J mm. ; upperside very pale ; throat and entire abdomen pure white, only across 

 the chest a very light grey band ; wing rather long, 145—148 mm. Iris brown; 

 feet and bill black. In no other form is the beak so large. 



Besides this form there seem to be several other subspecies : — (1) The typical 

 form from Northern Australia, the islands of Torres Strait, and Sonth-Eastern Xew 

 Guinea, with a wide area of pale grey from the breast to the throat, those from New 

 (iuinea {(lugiisti/i-on.-s f^harpe) perhaps paler (?). (2) The Solomon Islands birds 

 (Hubiana, F'auro, 51nnia), with wings only 1*1 — 140 mm. long. (H) The Am form, 

 with wing as long or lonijur than lonisiuilentsis, but bill smaller. More material is 

 necessary to show whether any of these forms can be admitted as subspecies. 



9. Edoliosoma amboinense tagulanum subs]i. nov. 



i ad. Above and below dark bluish slaty grey; chin, lores, cheeks, ear-coverts, 

 and malar stri2)e black, the black merging into the slaty grey of the back on the 

 ear-coverts. Remiges black, outwardly margined \vith the colour of the back, their 

 inner lining ashy white. Central pair of rectrices ashy grey, shafts and large spot 

 at tip black, narrowly fringed with grey. Outer pair of rectrices tijjped witii grey 

 for about In mm., next pair for about 2 or 3 mm., the rest of the rectrices black. 

 Wing 123, tail ca. 105, culmen from base 27 — 28, bill from end of feathers over 

 nostrils 17 — 1 7'o, from end of feathers on chin (gonys) 15, tarsus 23 mm. 



? ad. Cap bluish ashy grey, rest of npper surface greyish brown. Middle 

 rectrices pale brown, lateral brownish black witli rusty rufous tijis. Lores black. 

 Suborbital region spotted black and white. Under surface rusty buff with narrow 

 black cross-bars. Under tail-coverts pale cinnamon. 



The mitlc of this form agrees with E. amboinrnsc (irKeitsc in having the wings 

 margined with the colour of back. This can be strictly said of E. amboinense 

 tagulanum, while in the male of arue,me. the margins are after ;ill jialcr than tlu' 

 back. The male differs from that of aruense in a larger bill. 



I liave no doubt that Edoliosoma amboinenfse, aruense, giriji, miilleri, Icniiirostre, 

 tulautense, emxtncipatum, and others are all subspecifically related. 



111. Lalage karu (Less.). 



A form of /,. /■(//■/' is not rare nii Sndest Island. Its iris was found to be brown: 

 feet and bill black. 



(1 j The type of L. karu is from New Ireland. Birds from New Ireland and 

 New Britain I find to be very pale below, the rufous buff-colour of the abdomen (in 

 the males) reaching up to the breast, the feathers of the rump black with white edges. 



(2) From these birds, /,. Itarti karu, the males from Sndest differ in having 

 more white on the rnnip, tlierc being many wholly wliitc feathers, and tlu' abdomen 

 is generally paler bull'. 



(3) The specimens from St. Aignan again resemble more /-. Itaru karu, but 

 they seem generally ]ialer on the abdomen. The rump is as dark as in L. karu karu.
