12S NEW SPECIES OF ORNITHORYKCHUS, 
whatever of the animal is external and obvious, are just as 
much a part of its constitution, as the intestines, muscles, 
blood-vessels, or whatever of it is most internal and recon- 
dite ; and that, in fact, without a precise knowledge of the 
former, there can be no certainty with regard to the latter. 
Considered as scientific knowledge, the possession of mere 
external characters, without any thing else, is as despicable 
as that of mere anatomical characters, without any thing 
regarding external appearance, manners, habits, haunts, 
and uses. To produce any thing like perfect delineations of 
natural objects, it is necessary to attend to all the circum- 
stances of organization ; and although anatomy is useful, as 
tending to this end, external characters are not less so; 
nor can the mode of life, which results from the conforma- 
tion, be considered as an unessential part of the history of 
animals. Where anatomy and natural history have gone 
hand in hand, they have produced such men as Cuvier, 
Blumenbach, Lamarck, Blainville, — who, it may be said, 
are great anatomists, because great naturalists, and great 
naturalists, because great anatomists. But leaving to those 
who may have dissected Ornithorynchi, to inform us what 
species or varieties they have operated upon, I proceed to 
describe a new species, larger and somewhat more remark- 
able than that hitherto known. 
Ornithorynchus crispus, Greater Duck-bill, 
Specific Character. — Ornithorynchus pilis universis 
magis minusve apice curvatis, caudalibus superioribus 
geniculatim reflexis, implexis. 
Description. Beak very broad, complanate, dilatato- 
rotundate at the end. Nostrils small, round, subterminal,
