the libs, which here make a very obtuse angle at their junction with 

 the cartilages, or rather bones of sternal attachment. 



" The clavicles offer nothing remarkable. 



" The bones of the wings are short; the forearm and humerushe'mg 

 of equal length, — 4^ inches : the hand consists of the usual bones 

 in Birds, and is about 34- inches in length. 



"The femur, as in the Crane, is short and strong, measuring 3-j- 

 inches. The tibia is slender, measuring Si- inches in length; the pro- 

 jecting crista before its upper articulating surface is very bold : as in 

 the Crane, there is a large internal plate and an external pointed pro- 

 cess, with a deep hollow between ihem, occupying the front of the 

 upper end of the tibia. The fibula is, as usual, a slender stylet, and 

 3 inches long. The tarsus is 64- inches long, of a sijuared form to- 

 wards its upper extremity, with an anterior and posterior groove very 

 strongly marked, and a slighter groove on each side. The accessory 

 or little metatarsal bone, at the base of the hind toe, is very small, 

 and is situated about an inch from the lower extremity of the tarsus. 

 The toes are short and stout, but consist of the usual number oi pha- 

 langes. 



"■ Though the Cariama, in its osseous structure, exhibits but little 

 resemblance to the Birds of the Raptorial order, it approaches that 

 order very remarkably in the structure of the eye, which is surround- 

 ed by a firm consolidated osseous ring. This ring departs materially 

 in its formation from what obtains among the Grallaiores generally, 

 where it is imbricated and slight, and indeed scarcely merits the 

 name of osseous. 



" The choroid, the iris, and the lens present nothing remarkable. 

 The ciliary processes are 102 in number, and about the 12th of an 

 inch in length. The marsupium nigrum is strong, large in proportion 

 to the eye, and much elevated." 



In illustration of Mr. Martin's Notes, the mounted skeleton of the 

 Cariama was exhibited ; as were also preparations of several of the 

 viscera. 



The following Notes by Mr. Martin, of the anatomy of a specimen 

 of Buffons Touraco, Corythaix Buffonii, Vaill., were subsequently 

 read. 



" The death of a specimen of Buffon's Touraco in the Gardens of 

 the Society, has enabled me to investigate its visceral anatomy, and 

 to compare the details afforded by that species, with those given by 

 Mr. Owen respecting the Corythaix porphyreolopha. The individual 

 in question was a female of the Cor. Buffonii. In the total length 

 of the head, neck and body, exclusive of the tail-feathers, it measured 

 8i^ inches. 



" On openmg the abdomen, I found the viscera thus arranged. 

 Below the edge of the siernum, (which is a very short bone, its keel 

 being only 1 y inch long,) appeared the two lobes of the liver, (highly
