Puffinus, Briss. 



Vandieman's Land. 



Cranium very similar to the foregoing. When the horny covering of the bill is cleared 

 away (which it is in this specimen), the nares are found to penetrate under the tube 

 directly backwards, with a distinct septum between them, the upper part bony, and 

 the rest cartilage. The nares are terminated by an orifice, turned upward, which is of 

 soft cartilage, and which, I suspect, the bird has the power of expanding or contract- 

 ing, and the whole is covered by a hollow horny tube. The palatine bones are similar 

 in shape, but with the outer edge of the hinder portion turned more downwards ; the 

 post orbital processes are very broad at their extremities, whereas they are pointed 

 in the foregoing. 



Sternum short, broad, with broad and shallow fissures on each side of the keel 

 externally, to which are two small oval foramina. Eemainder of the sternum similar 

 to the foregoing. 



Pelvis with a keel between the anterior half of the ilium, and not anchylosed to it. 

 Remainder similar to the foregoing. 



Wing-bones. Ulna longer than the humerus ; thumb very long, reaching to more 

 than half the length of the metacarpus. 



Leg-bones. The extension of the proximal end of the tibial crests reaching beyond 

 the end of the femur, and very broad. 



Remaining bones as in the preceding.
