the tooth was directed a little outward it has formed a spiral, very 

 similar in shape and size to what would be found by cutting off 

 the last two turns of a closely-twisted corkscrew. 



The left incisor being deflected inwards has entered the superior 

 maxillary bone again very near the origin of the right incisor, and 

 after penetrating the bone for nearly a quarter of an inch, and 

 completed rather more than a circle, it must have found the 

 resistance too great to overcome, and ceased growing, otherwise it 

 should be as long as its fellow. 



The lower incisors describing so much longer a curve have 

 been more subject to accident, and have apparently been broken, 

 the left quite recently, possibly when captured, as was the right 

 upper, to little more than its normal length. The right, which is 

 about half an inch longer than it ought to be, had grown through 

 the upper lip, and by continual pressure produced a slight but 

 decided malformation of the intermaxillary and nasal bones. 



The right lower maxilla is a little longer than the left, but 

 whether this was the cause or result of the deformity I could not 

 say. The first curve of the right upper incisor is a good deal 

 smaller than it becomes afterwards, showing the youth of the 

 animal on the first occurrence of the irregularity. 



It is strange that with such disadvantages the animal should 

 have been able to maintain its condition, and that the vascular 

 tissues should have permitted themselves to be pierced as they 

 were without the least sign of inflammation.

Saddleback {Cvft&^\on carunculatus, Gmel.). — The "saddleback" 

 of the settlers (" ticke" of the natives), which a kvf years since was 

 commonly met with in the more thickly wooded portions of Banks 

 Peninsula, is now of rare occurrence there. The extensive area of 

 growing timber at the Little River Bush will probably be its last 

 refuge in that part of the country, so rapidly is the Peninsula 

 becoming disforested. Although we have met with, and have known 

 of the nest of this striking looking bird in the more open parts of
