Mixed Beasts by Wallace Edwards and Kenyon Cox

From chapters.ca:
Prepare to be amazed by a collection of beasts such as the world has yet to behold. To track down these curious creatures, Professor Julius Duckworth O'Hare, Esq., the roving zoologist, travelled to the far corners of the globe. In this fascinating publication of his findings, the Professor commissioned the poetic talents of Kenyon Cox and the artistic powers of Wallace Edwards to bring his expedition to life in the form of an illustrated field guide. In these pages lurk bizarre beasts, such as the Bumblebeaver and the Rhinocerostrich, depicted in their natural environment. Readers possessing a sharp eye and an inquisitive nature will be rewarded with exotic flora and fauna hidden in each remarkable painting.
