PLATE VI. 
This bird was met with at Montereale. The gallant and enterprising commander of the expedition 
will, I trust, accept this dedication of a beautiful species, as a tribute of gratitude for his services to 
science, as well as an offering of friendship.

PLATE VII. 
This species seems to have been found in abundance at San Bias and Mazatlan. I have dedi- 
cated* it to the able and ingenious surgeon of the expedition, whose exertions contributed much 
to our knowledge in every branch of science ; and whose notes, more particularly on the internal 
structure of many of the birds in the collection, form the most valuable part of the present observa- 
tions. 
Mr. Collie makes the following observations on this bird : — “ The lower larynx was simple; the 
stomach simple, muscular and membranous, and was stuffed with white flatfish berries, without any 
gravel. The cceca are small, the left about one-third of an inch long, the right a little longer.”

PLATE VIII. 
There are two specimens of this species in the collection, differing, as above described, in their 
colours. Were we to judge from analogy, the more brilliantly plumaged bird would be the young, 
the more plainly coloured the adult ; as is the case in the nearly allied group, the Pine Grosbeak, 
Corytlius enucleator, Cuv. 
* Shortly after the plate of this bird had been completed, and the text printed off for the Zoological Journal, 
I received a letter from my friend Mr. Children, requesting me to name the species after Dr. Burnet of the Haslar Hospital 
of Portsmouth, who had presented the British Museum with a fine specimen. I was sorry to have been thus unable not 
only to comply with the wish of Mr. Children, but to pay a compliment to Dr. Burnet, whose zeal in science well 
merited it. The editor of the translation of M. Cuvier’s “ Animal Kingdom,” not being aware of these circumstances, 
subsequently named the bird according to Mr. Children’s original desire. By an unfortunate error which simultaneously 
took place on the part both of the engraver and the printer, the bird is named Bernet’s Magpie ( Pica Bernettii ) in the 
plates of that work, and Bennett’s Magpie in the text. An additional name has within the last month (Dec, 1830) 
been given to the species, already amply provided with synonyms — that of Pica ultramarina.
