though the jaws be open beneath the surface. Tlie trachea is a 

 straight simple tube ; it was f'ound in this animal to consist of fifty 

 rings before its bifurcation, its length being 3^ inches. A little 

 below the bifurcation, on each side, was a small glandular body, 

 similar to that seen in Birds, just where the trachea enters the thorax. 

 The bifurcations were observed to run a considerable distance into 

 the substance of the lungs before they blended into it. 



"Though difFering in a few minor points, the visceral anatomy of 

 this species bore, on the whole, a close resemblance to that of the 

 Croc. acutus, of which the details given by Mr. Ovven are already 

 pubiished in tlie ' Proceedings of the Committee of Science and 

 Correspondence' of this Society, Part I. pp. 139 and 169." 



A specimen was exhibited of the Stanley Crane, Anthropoides pa- 

 radisccus, Bechst. ; and Mr. Yarrell called the attention of the Meet- 

 ing to the conformation of its trachea, which corresponded perfectly 

 with the one figured by bim in the ' Linnean Transactions.' He 

 remarked, that as the present Bird had lived for upwards of three 

 years in the Society 's Menagerie, it seemed probable, from this co- 

 incidence of form, that no increase in the extent of the fold of the 

 trachea is occasioned by increasing age. 



The reading was concluded of an anatomical description, by Mr. 

 Reid, of the Patagonian Penguin, Aptenodytes Patachonica, Forst. 



" The specimen, an adult malė, vvhose dissection forms the sub- 

 ject of the follovving paper, vvas captured at East Falkland Isle, 

 in iatitude 51° 32' south, by Lieutenant Liardet, R. N., and was 

 brought to England in H. M. S. Snake, and presented by that gen- 

 tlenian to P. C. Biackett, Esq., by vvhose kind permission I was al- 

 lowed to examine it in detail : the results of this dissection I now 

 beg respectfully to iay before the Society. Ovving, hovvever, to the 

 length of time which had elapsed subseąuently to its capture, and 

 to the manner of its preservation (in rum), — together with a wound 

 on the inferior part of the neck, and others in the mouth, added to 

 Severai bruises, — part of my description vvill not be so perfect as 

 could be desired. 



" The bones are very hard, compact, and heavy, having no aper- 

 tures for the admission of air; but they contain, especially the bones 

 of the extremities, a thin oily marrovv. Thejbramina for the trans- 

 mission of the blood-vessels of the bones are small. The periosteum 

 is tbick and fibrous. 



" The cranium is short and broad, and is united into a single bone, 

 with very little appearance of suture or harmony : superiorly it is 

 flattened ; posteriorly, towards the occiput, it is rounded; it declines 

 obliąuely forvvards; and vvhen it attains the front of the orbits it is 

 suddenly truncated to meet the superior niandible. 



" The orbits are large, and separated only by membrane. Above 

 eacli orbit there is ajbsm, which is decper and broader behind than
