specimen {$,85.8.1.98, " Aiidamans '') is, in addiiion, distinctly 

 smaller than any specimen of Pt. melanotus (see tables, pp. 230- 

 281). 



The present state of our knowledge of the hats of the Pt. 

 melanotus group inhabiting the Nicobars and Andamaiis may be 

 briefly epitomized as follows : — 



(1 ) All specimens (ten) examined by the writer from the Xicohars 

 (Tillanchong, Trinknt, (Jreat Nicol)ar) are Pt. inekoiotns, and all are 

 characterized by a bright mantle and a more or less extended area 

 of bright colour on the centre of the underparts. In the series 

 examined females are indistinguishable in colour from males. No 

 uniform blackish specimens from the 2sico)iais have been seen by 

 the writer. 



(2) Four specimens have been examined from the Andamans, 

 viz. : — 



one, from Rutland I. (South Andaman^), with bright mantle, 

 but practically uniform dark underparts, this latter being the onh/ 

 point in which it differs from Pt. melanotus. This is " Pt. tijtleri." 

 It may be a distinct species, or a local race of Pt. melanotus, or 

 merely an individual variety v 



three practically uniform blackish specimens, representing 

 both sexes, two of which are labelled " Andamans," one Ross I., 

 Port lilair. South Andamans. They might be considered without 

 much hesitation merely melanistic varieties of Pt. melanotus or 

 " Pt. ti/tleri," if not for the fact that the single fully adult specimen 

 differs from both not only in colour but also bv its smaller size.
