 George Gulliver, Esq., in the Chair. 



A foetal Condor, extracted from an egg laid in the menagerie, vras 

 exhibited to the Meeting. The egg had been placed under a com- 

 mon hen, which remained sitting on it for six weeks and two days. 



The length of the specimen is 5f inchcs ; the extreraities, particu- 

 larly the legs, are imperfectly developed, but the head had acquired 

 a specific vulturine character ; a strong line of downy filaments ex- 

 tends along the length of each pectoral musele ; all the other parts of 



the body are quite bare.

Mr. Gould exhibited to the Meeting three new species of the family 

 of Trochilidce, which he thus characterized : — 



Trochilūs (Petasophora) coruscans. Troch. strigd intense cte- 



ruled a mento per genas productd in aures, quce erectce ut cristulce 



conspicantur ; plumis mediam gulam sįuamatim tegentibus nitide 



viridibus, cereo et coccineo colore resplendenlibus ; medio ubdomine 



cyanco ; tectricibus cuuda inferioribus sordide viridibus, ad apices 



stramineis ; alis purpurascente fuscis . 



Crown of the head, all the upper surface, wing-coverts and flanks 



green ; tail-feathers very broad, steel-blue, with green reflections, 



and crossed near the extremity \vith a broad band of a blackish hue, 



as in the allied species Anais and serrirostris ; a band of rich pure 



blue commences on the chin and extends along the sides of the 



cheeks and on the ear-coverts, which when erected forra conspicuoifs 



tufts ; the scale-like feathers of the centre of the throat rich shining 



green, \vith bronze and duU crimson reflections ; centre of the abdo- 



men blue ; under tail-coverts dull green, broadly tipped with buif ; 



•wings purplish brown ; billblack; feet brown. 



Totai length, 5į inches ; bill, \-į^ ; wing, 3 ; tail, 2. 

 Hab. The part of South America of whicli this bird is a native is 

 unknown. 



This beautiful species is rather less in size than P. Anais, from 

 which and every other species it is distinguished by the beautiful 

 marking of the throat, the greater extent of the blue on the abdomen, 

 and by the gteater breadth of the feathers of the tail. 

 In my own coUection.
