as we have before suggested, our only clue to the original, or even primitive, colouration of animals is lost and buried in the records of the geological past, in which we find structure—scantily and often confined to typical portions—but of colour nothing, a much larger field is open to the palaeontologist who seeks for the origin of that animal structure which is so often alike described under the terms of "protective resemblance" and "mimicry." Friends and foes of those theories too frequently—both for attack and defence—conceive the wonderful protective disguises in nature as having been evolved during the time of present Zool. 4th ser. vol. III., July, 1899.
