The only example o f this species we have yet met with is the typical specimen described
by Mr. Sclater as above refen-ed to, from which also our figure has been taken. The example
in question belongs to the Museum d’Histoire Naturelle o f the Jardin des Plantes, and we have
to express our great obligations to the authorities o f that establishment for allowing us the use
of it for this work.
M. Bonnecourt, the collector o f this unique specimen, obtained it in Sta. Lucia in the year
1850. It is labelled “ Xe Gi'ive Trembleuse” which is, as we have already remarked, the same
name that C. ruficauda bears in Guadeloupe. The sex is noted to be female, but the male is,
without doubt, scarcely different.
In a small series o f drawings o f the bii-ds o f Sta. Lucia by Lieut. Tyler, in the Zoological
Society’s Library, is a figure, evidently intended for this bfrd, marked “ The Ti-embler.”
The present species is at once distinguishable from its two allies by its long bill, but in
other points o f structure does not materially differ from them. The fii-st (spui-ious) prunaiy is as
large as iu the other two species, measuring 1*5 inch from its insertion, and being rather more
tluiii half the length o f the second primary. The thii-d is slightly shorter than the fourth, fifth,
and sixth, which are equal and longest. The present specimen o f G. macrorhyncka has the
tarsi covered anteriorly with a continuous h omy sheath, the divisions o f the tarsal scutes having
become almost obsolete. In specimens o f C. ruficauda and C. gutturalis, these divisions are
distinctly indicated and the scutes are five in number, which is probably the normal form of
the genus.
