This bird ditters from all the knovvn species by its small bill, vvhich 

 is much sliorcer than the head ; and by the rich golden-purple tail 

 composed of very broad feathers, 



Trochilus eurypterus. Troch. suprajusco-viridis, suhtus ci- 

 nereo viricli(įne variegatus ; caudd rotundata, atro-aureo-viridi, 

 rectricibtis lateralibiis apice cinereis ; alis latissimis Jusco-atris : 

 rostro brevi, recurvato, mandibula inferiore albd. 

 Longitudo, 4į unc. 



Trochilus flavescens. Troch. aureo-viridis ; capite guldgue 



splendenti aureo-smaragdinis ; caudd subfurcatd, albo-flave- 



scenti, rectricibus lateralibiis ad margines, mediisque totis aureo- 



olivaceis ; alis airo-Juscis, subtus pallide rufescenlibus : rostro 



mediocri, recto. 



A species resembling Troch. rubineus, Auct., in its size, and 



nearly allied to that bird. It difFers, hovvever, in the collar, vvhich 



is golden green, and in the tail-feathers, which are (with the ex- 



ception of the middle pair,) yellowish white. 



Trochilus Gouldii. Troch. viridis ; jugulo pallide smaragdine ; 

 caudd longissimd, forjicatd, rectricibus rotundatis, exterioribus 

 4<5 uncialibus nigris, ad apices aureo-viridibus, mediis hrevibus, 

 ccBteris gradatis aureo-viridi splendentibus ; alis mediocribus ro- 

 tundatis : rostro jmrvo, recto.

The most remarkable feature in this elegant little bird is its long 

 and luminous green tail, in the form of which and in the arrange- 

 ment of the feathers it approaches the Jire-tailed Humming-Bird, 

 Trochilus sparganurus, Shaw, and likewise the Nouna Koali of M. 

 Lesson's * Supplennent,' pi. 35. 



Preparations were exhibited of the stomach, and of the tongue, 

 larynx and trachea of a Ja^ruar, Felis Onęa, Linn. They were ob- 

 tained from an individual which lately died at the Society's Gar- 

 dens, respecting the dissection of vvhich Mr. Martin read, at the re- 

 quest of the Chairman, the foUovving notes. 



" The Jaguar vvhich died a fevv vveeks since vvas a full grown fe- 

 male, and although in height less than the Leopard, appeared more 

 rauscular and strongly made. The length of the body, exclusive 

 of the tail, was 3 feet 2 inches ; the tail measured 2 feet. 



" The small clavicles vvhich are found in the foline tribe in general, 

 were in the present instance barely 2 inches in length, simply im- 

 bedded in the museles of the chest, and vvithout any ligamentous 

 attachment either to the scaptdce or sternum. 



" The lungs consisted of three lobes on theleft side, and four on 

 the right, of which the posterior vvas furnished vvith an appendix 

 or process, situated in a cavity or kind of inferior mediastinum hav- 

 ing its vvalls (vvhich vvere incomplete on the right but complete on 

 the left side,) formed by a reflexion of the pleura passing from the 

 heart, the diaphragm constituting its base. This structure is, I be- 

 lieve, to be found in most Mammalia.
