In clear, usually more I the color may be le crustaceans it is all vertebrates the ily of some slight exceptions possess. only colorless corpuscles, but all vertebrates have colored cells which invariably outnumber the other variety, and display forms and sises which are sufficient- ly constant to be characteristic. In all groups below mam- mals the colored cor- puscles are oval, mostly biconvex, and nucleated dur- ing all periods of the animal's existence; in mammals they are circular biconcave disks (except iu the camel tribe, the cor- puscles of which are oval), and in post- embryonic life vrith- out a nucleus ; nor do they possess a cue, cell-wall. The red cells vary in sise in different groups and sub-groups of animals, being smaller the higher the place the animal occupies, as a general rule; thus, they are very large in verte- brates below mammalu, in some cases being al- most visible to the un- aided eye, while in the whole class of mam- mals they are very mi- nute ; their numbers also in this group are vastly greater than in others lower in the scale.
