defined. M. pulcherrimus had the western limits of its habitat 

 in the Hills themselves. From that line M. Leucopterus held 

 sway until within the ocean influence, when M . splendens appeared 

 and continued to Mogumber. Pomatorhinus superciliosus ex- 

 tended from the Hills for 20 miles westward, and then disappeared 

 with the red soils and gimlet gums. Petra'ca goodenovi was not 

 found at the Hills or in their vicinity, but was first met with 

 at some 27 miles westwards, and thereafter continued up to a 

 point within 6 miles of Mogumber, but not farther. At this 

 point PetrcBca campbelli was first seen ; and this would appear 

 to be the line of osculation. Manorhina obscura was not seen 

 until we reached Mogumber. We did not anywhere meet with 

 such common coastal forms as Meliornis longirostris, M . niysta- 

 calis, Acanthochcera lunulata, and Acanthorhynchus superciliosus. 

 Evidently we were some distance from the southern limits of 

 such species as Climacteris superciliosa, Ephthianura aurifrons, 

 E. tricolor, Acanthiza robustirostris, Xerophila ccbstaneiventris, 

 all of which are found at Wurarga and Day Dawn, some 200 miles 

 northward. 



Hereunder I tabulate the results of my observations as regards 

 the limits of certain species mentioned before : — 



SOUTHERN LIMITS. 



Malurus leucopterus Misocalius palliolatus 



Acanthiza pallida Dryniaosdus pallidus. 



NORTHERN LIMITS. 

 Malurus pulcherrimus Ptilotis ornata 



Calamanthus montanellus Caly ptorhynchus baudini 



Cinclosoma castanonotum Platycercus icterotis 



Melithreptus leucogenys Strepera plumbea 



Glycyphila fulvifrons Petrceca campbelli. 



Ptilotis cratitia 



It would appear that Malurus pulchcrri)nus, Calamanthus 

 montanellus, Cinclosoma castanonotum , and Ptilotis ornata are 

 supplanted at Wurarga (200 miles north) by Malurus assimilis, 

 Calamanthus ca)npestris, Cinclosoma cinnamomeum , and Ptilotis 

 plumula respectively. Climacteris rufa, which is said to have 

 a northerly range, is represented at the same place by Climacteris 

 super ciliosa. 



EASTERN LIMITS. 



Petrceca campbelli. 



Petrceca goodenovi and its doubtful ally, P. ramsayi, evidently 

 take the place of the P . campbelli at Wurarga. The former is 

 found in great numbers at Rottnest Island, which must be taken 

 for the present as its most southern habitat. 



WESTERN LIMITS. 



Sericornis brunnea Glycyphila albifrons 



Acanthiza uropygialis Misocalius palliolatus 



Malurus pulcherrimus Pscphotus multicolor. 

 Calamanthus montanellus
