Lear, Edward: Illustrations of the family of Psittacidae, or parrots: the greater part of them species hitherto unfigured, containing forty-two lithographic plates, drawn from life, and on stone

Source.
Edward Lear, popularizer of limerick, Victorian purveyor of nonsense, founding crackpot for the next century's middlebrow cocktail verse, was also an exacting naturalist. I am wagering that it is within character that his choice for study, here, was parrots.

Jessie Willcox Smith

Water Babies exhibition.

Charles Kingsely's Fairy Tale, with the illustrations in context.

"Dear Grandpater -- Have you seen a Waterbaby? 
Did you put it in a bottle? 
Did it wonder if it could get out? 
Could I see it some day? -- Your loving Julian."

A gifted illustrator certainly of preciousness, also of whimsy, Jessie Wilcox Smith is the artist of this fantastical series, from Kingsley's original Water Babies edition.
