In thii specimen, the ossification continued from the lacrymal beneath the orbit dors not 

 quite rrach the postfrontal : the mastoid terminate* freely : the parocdpital* are slightly ex- 

 tended backward! at their extremities. Of the 18 Tertebne between the skull and Mcrum. 

 the six posterior support move-able ribs, and of these the last four pairs articulate with the 

 sternum : the sacral ribs are wanting.

1458. The left half of a vertically-bisected cranium of a Parrot (Pnttaciu). 



The suborbital process of the lacrymal approaches, but does not join, the mastoid : the 

 [x>st frontal is a mere tubercle : the |>aroccipital is slightly produced backwards : the tentorial 

 ridge dividing the prosencephalic from the mesenccphalic cavity is more developed than in 

 the Crane, as is also the ridge to which the falx is attached. The petrosal fossa is compara- 

 tively shallow.

1459. The skeleton of the Black-billed Toucan (Rnmphasio* luteus, Gmel., Linn.). 



Latham, in his ' History of Birds,' edit. 1822, vol. ii. p. 280, when giving the generic cha- 

 racters of the Toucan, mentions but one smooth-billed species, as an exception to the others . 

 all of which, he observes, have the edges of their mandibles more or less irregularly notched 

 or serrated. Rampkaitot glaber is the species cited as differing in this particular from the 

 rest ; although in most other respects resembling the female of the Green-winged Toucan 

 (RampAtutot riridii). The bird from which the above skeleton was made was in a living 

 state in the menagerie at Exeter Change, and appeared to be full-grown. Except in the cir- 

 cumstances of the edges of the bill being jierfect ly smooth (which, if observed, is omitted by 

 Latham), and in the general colour of the body, which was a dusky grey, the rest of the 

 plumage and external characters strictly corresponded with his description of the black-billed 

 ' species.
