This very distmct form was separated by me, provisionally, from P. 

 nanus., as P. minimus., iii the paper above cited, without being described 

 in detail. The fourteen specimens subsequently received bring out 

 very strongly its distinctive characters, and show it to be very different 

 indeed from P. nanus and its nearer allies, from which, in any plum- 

 age, specimens may be distinguished at a glance.
