American L. rufaxilla (Rich. & Bern.), but with the top of the head of a 
deep lead-colour. The second resembles L. cassini (Zool. Rec. iv. p. 113) 
from Panama, but has the breast paler, with a vinous-coloured tinge, and the 
upper part of the belly of a deep bulF. A list of eight species of the genus 
known to the authors is added. P. L. Sclater & O. Salvin, P. Z. S. 1868, 
pp. 59, 60. 
Leptoptila riottii is described as a new species from Oosta Rica, coming 
nearest to L. hrochyptera ; but that has the forehead greyer and the cheeks 
without any vinaceous tinge ; the new species is a little darker on the breast 
and sides, tlio under wing-covorts are brighter, and the inner webs of the 
quills cinnamon-colour. The differences between this and L. albifi'onSj L. ver- 
reauxi, and L. rufaxilla are also pointed out. Q. N. Lawrence, Ann. Lyc. 
N. H. New York, 1868, pp. 137, 138.

Geotrygon costaricemis and G. cceruleiceps are described as two new species 
from Costa Rica. The first is allied to the group represented by the Cuban 
G. caniccps, and the colour of the breast is nearly the same in each, but the 
new bird has longer and stouter feet. The second is said not to require com- 
parison witli any other species ; its most distinguishing feature is the extent 
of blue on the head. [Referred to G. chiriquc7isis, Scl. vei'a (vide siqyrdL).

An abstract of Prof. Owen’s paper on the Osteology of Didus inepMs (Zool. 
Rec. iii. pp. 104, 105), to which are prefixed a few remarks on its history 
and other particulars (some of no small interest) which have escaped the 
notice of former investigators. [C/’. Ibis, 1868, pp. 479, 480.]

Tiioso resetirchcs are based chielly on the labours of Messrs. Clark, 
Coquerel, Gervais, and A. Milne-Edwards (Zool. Rec. iii. pp. 104-106) ; and 
the author, who had not seen Prof. Owen’s paper on the Osteology of Didu^ 
(he. cit.), argues in favour of its having been a Grallatorial bird, and pro- 
poses to divide that Order into six families : — (1) Alectoridce, including Pa- 
lamedetty Psophia, Diclioloplius, and Otis] (2) Dididve) (3) Cliaradi'iidcB * 
(4) Scolopacidcs y (5) Herodiiy comprising this, Platalea, Tantalus, Ciconia, 
Anastomus, Dramas, Scopus, Balmiiccps, Ardea, and Gy'us ; and lastly (6) PaD 
lidee, with Rallus, Gallinula, Poiphyrio, Parra, Fulica, and Podoa. \^Cf. Ibis,

This work contains an account of an old picture of Didus meptus lately 
found in the private library of the Emperor of Austria, as well as one of 
another bird [see Rallidm'’'~\. These are shown, with great probability, to 
have been painted by Iloefnagel, a Butch artist, who flourished towards the 
1868. [voL. V.] II
