'iliis is a rare species and has been iioorly nudei'stood in this country. This 

 confusiou has l)ecn due to two factors: First, the absence of the species from all 

 our ccdlections, and, second, becanae Mr. Bentham referred to it ('i'rans. l.inn. 

 Soc. XXX.) an nndescrilxid 8peci<\s, which ])rovi'8 to be a species of Alhiz:'ui. I 

 shoulil state here that it is through the kindness of Jlr. Hemsley, of Kew, that 

 1 have been able to clearly fix upon this as the true /.. marroi>hyUn.

 type seem to be the same. They may, lioW(^vcr, as snggc^sted by Mr. Hemsley, 

 belong to a different species.
