FIELD-WREN. 
from G. c. howei in having less red on the crown and being paler above ” ; and 
the Lake Way, West Australia, form as C. c. wayensis, stating : “ Differs 
from C. c. campestris in having the head deeper rufous and the back slightly 
darker and less streaked ; the flanks also showing huffy instead of uniform.” 
It is almost impossible with the series yet available to dogmatise, but 
it seems that there may be an eastern and a western species representing each 
other and never meeting or intergrading. 
The names would then be arranged thus : 
Calamanthus campestris campestris Gould. 
South Australia (Port Augusta). 
Galamanthus campestris ethelce Mathews. 
Eyres’ Peninsula, South Australia. 
Galamanthus campestris macgillivrayi Mathews. 
Broken Hill district, New South Wales. 
Galamanthus campestris isabellinus North.. 
Central South Australia. 
Galamanthus campestris howei Mathews. 
Mallee of Victoria. 
The species name of the western one would be : 
Galamanthus rubiginosus Campbell 
and the subspecies at present admissible : 
Calamanthus rubiginosus rubiginosus Campbell 
Point Cloates district, Mid-west Australia. 
Galamanthus rubiginosus dorrie Mathews. 
Dorrie Island, West Australia. 
Calamanthus rubiginosus wayensis Mathews. 
Lake W T av district, West Australia. 
Galamanthus rubiginosus hartogi Carter. \ 
Dirk Hartog Island, West Australia. 
Calamanthus rubiginosus peroni Mathews. 
Peron Peninsula, West Australia. 
Apparently there are many more subspecies to be differentiated. As to 
the value of structural differences this species shows more differences from 
Galamanthus than does Hylacola, and it is advisable to introduce a new 
sub-generic name, Eremianthus, selecting Calamanthus campestris wayensis 
Mathews as the type. The bird has the bill stouter, the wing formula has 
the first primary less than half the third, the third to the tenth subequal and 
longest and the secondaries equalling these ; the tail nearly even and shorter, 
and the feet more delicate, the tarsus apparently booted and the toes more 
slender ; the hind-toe normal, not at all elongated.
