Parvipsitta

(syn. Glossopsitta Ϯ Little Lorikeet G. pusilla) L. parvus  little; Mod. L. psitta  parrot  < Gr. ψιττακη psittakē  parrot; "GLOSSOPSITTA.   ...   Three species are included in this genus, the type being larger than the other two. For the last two I propose the new subgeneric name PARVIPSITTA, naming Psittacus pusillus White as type.  They differ in their smaller size, their smaller and narrower bill more projecting, with longer tip and obsolete notch after tip, their proportionately shorter tail and smaller legs and feet. It is possible that internal differences may be observed, as in the case of Lathamus to be hereafter noticed.  As a small item I have noticed that the typical species is recorded as laying two eggs only, while the smaller species lay four or five eggs.  ...  I would conclude that G. pusilla was closer to Hypocharmosyna than to Glossopsitta typical." (Mathews 1916).
