428 MR. G. R. GRAY ON NEW BIRDS [Dec. 10, 



which present differences in their colour, &c., according to the island 

 that they inhabit. 



PODARGUS STJPERCILIARIS, G. R. Gr. (PI. XLII.) 



This fine species differs from Podargus mai'moratus in its deeper 

 rufous colour on the upper surface, and in the white spots on the 

 wings, and also in the numerous patches of white on the under sur- 

 face of the body ; but principally in the well-marked white eye- 

 brows. 



Total length 14" 3'", bill from gape 2" 3'", wings 7" 9'". 



Hah, AYaigiou. 



Halcyon torotoro. 



Of this bird M. Lesson figured the male, from which the female 

 differs in having a black crown and nuchal collar of the same colour. 

 The Waigiou and Mysol examples vary from Lesson's figure in 

 having the back and wings of a yellowish green, and the abdomen 

 pale rufous instead of white. 



Ptilotis sonoroides, G. R. Gr. 



This species approaches to Ptilotis sonora, Gould. It is of a 

 brownish grey, with the lores and behind the eyes black ; beneath 

 the latter there is a bright yellow streak ending in a patch of pure 

 white ; beneath, the body is yellowish white, streaked with fuscous 

 along the shaft of each feather ; quills and tail bright ohvaceous yel- 

 low on the outer margins. 



Total length 8" 9'", bill from. gape I'' 1'", wings 4" 6'". 



Uab. Waigiou. 



"&■ 



Ptilotis similis, var. 



Differs from the typical Ptilotis similis in having the bill shorter, 

 and the patch of yellow on the ear of a larger size. 

 Hab. Waigiou. 



Ptilotis flaviventris. 



This species seems to vary in the different islands ; for example, 

 that of the Island of Waigiou is olivaceous above, with a greater quan- 

 tity of yellow on the breast, and is also of a purplish brown on the 

 sides of the abdomen and under tail-coverts, while the length of the 

 wings is 3" 7'". 



That from IMysol has the sides of the abdomen and under tail- 

 coverts inclined to rufous, while the wings are 4'' 3'" in length. 



Ptilotis megarhynchus. 



The Mysol example agrees best in colour with the Dorey specimen, 

 while the measurements are most like those of the Aru specimens. 

 The bill is 1" 61'" in length. 



The Waigiou specimens are of a dull brown, with grey on the head, 

 neck, and breast. The bill is 1" 8"' in length, while in measurements 

 it agrees best with the Dorey specimen.
