(16) The karyotype of the platypus (2n = 52) has several features in common with those of the echidna species; six pairs of large autosomes, many pairs of small (but not micro-) chromosomes, and a series of small unpaired chromosomes which form a multivalent at meiosis.
(17) Neurohypophysial hormones of platypus seem similar to those of echidna, the other living prototherian, and to those of most placental mammals.

(20) Statistical comparison of amino acid composition of the component chains with other immunoglobulin heavy chains suggests that echidna gamma chains are more closely related to eutherian gamma chains than to the 7S Ig heavy chains from amphibia or aves.
Pangolin
Definition:
(n.) Any one of several species of Manis, Pholidotus, and related genera, found in Africa and Asia. They are covered with imbricated scales, and feed upon ants. Called also scaly ant-eater.

(6) Our results suggest that there is considerable divergence in Chinese pangolins, and brown and dusky Chinese pangolins may be quite different forms or, at least, belong to different maternal groups.
(7) Eimeria tenggilingi is described from the pangolin or scaly anteater, Manis javanica, in Malaysia.
(8) The investigation does not indicate any special relationship between the New World edentates and the Old World pangolins, whereas the marked difference in the course of the internal carotid artery in recent edentates stresses the independent development of the South American anteaters compared with that of the two other edentate groups (armadillos and tree sloths).
