Descriptions of two New Yertebates in Mr. Saville-Kent's 



Collection. 



Among the birds brought from Cambridge Gulf is a young 

 female Pachycephala which is identical with an adult of the same 

 sex previously procured at Kimberley on the Gulf of Carpentaria in 

 company with two males. These which have hitherto been sup- 

 posed to be P. lanoides, Gl'L, must now be considered to constitute 

 a distinct species. The writer proposes for it the name P. fretorum. 



Adult male. — Above ash grey washed with olive green, but 

 losing that tint on the rump ; upper tail coverts dark-brown 

 broadly margined with ash grey. All the head and face and ear 

 coverts black : si les of neck and a narrow pectoral collar black, 

 broadly margined with chestnut in continuity with a broad nuchal 

 collar o c the same. Wings brown: primaries narrowly, secondaries 

 and coverts broadly edged with ash-urrey : chin, throat, lower chest, 

 abdomen, axillaries and under-wing coverts white : flanks grey : 

 tail dark-brown, feathers margined laterally and apically with ash- 

 grey ; legs and feet light-horn brown : bill black.
