EUDYPTULA MINOR IREDALEI. 
THE CHATHAM ISLANDS LITTLE PENGUIN. 
(Plate 67.)* 
Eudyptula minor IREDALEI, subsp. n., Chatham Islands. 
Adult male. Differs from E. minor minor in its smaller size and darker coloration, and by 
its short, thick biU — exposed portion of culmen 34 mm., depth 16 ; Type no, 243 in 
my collection. 
When the Plates of the Penguins were prepared, now over two years ago, I 
admitted two subspecies of Eudyptula, viz. E. minor and E. undina. The 
most typical bird of the latter species, to me, was one obtained in New Zealand 
waters. As at that time the New Zealand and Australian species were confused, 
I figured the above new subspecies as Eudyptula undina. It was a “ good 
species” to me, as it was easily recognisable, in addition to its smaller and 
darker coloration, by its short thick bill. 
My recent researches have enabled me to trace this form as the subspecies 
breeding on the Chatham Islands. I am, therefore, distinguishing it as above, 
and publishing the prepared Plate, although I admit it is not an Australian 
bird. This instance will show the difficulties to be contended with through the 
preparation of the Plates some years in advance of the text. 
* The Plate is lettered Evdyptula undina.
