Monotremata

Naturally enough, the geographer wished to preserve this interesting specimen of monotremata, and wanted to stow it away in the luggage; but M. Olbinett resented the idea so indignantly, that the SAVANT was obliged to abandon his project. ❋ Unknown (2003)

The heart is at first a simple pulsating vessel, like the heart of the lowest fishes, and the excreta are voided through a common cloacal passage -- an anatomical feature so characteristic of the lower vertebrata, that it occurs in no fully formed member of the mammalian group, with the exception of the bird-like order of monotremata, which takes its name from presenting so striking a peculiarity. ❋ George John Romanes (1871)

Generally, however, the mammalian remains of this period belong to what are considered the lower classes -- the monotremata and marsupialia. ❋ Unknown (1854)

Now these are animals at the bottom of the mammiferous class, adjoining to that of birds, of whose character and organization the monotremata largely partake, the ornithorynchus presenting the bill and feet of a duck, producing its young in eggs, and having, like birds, a clavicle between the two shoulders. ❋ Robert Chambers (1836)

Next to them are the monotremata, which are entirely peculiar to this portion of the earth. ❋ Robert Chambers (1836)

20 To these may be added the occasional existence of two small episternal centers, which make their appearance one on either side of the jugular notch; they are probably vestiges of the episternal bone of the monotremata and lizards. ❋ Unknown (1918)
