 Yet the variations in individuals is such that the two 

 species are determined with difficulty.

Hanley. MS. in Coll. 



Hah. Pacific. 



Neither the P. virgatus var. so marked in the 

 British Museum, nor the "strigatus var." in Mr. 

 Hanley's Collection seem to me to agree with the 

 type of Mr. Smith's P. (■//•;/'(/".*, but resemble each 

 other, with the exception that the furmer has a little 

 purple in the lips.
