sketch, "had to be begun at half past five in the morning. It was there that the Papilio Gundlachianus flew. I had to walk two leagues, stand three hours, and then walk back two leagues more. The heat was unbearable." This Papilio is highly valued by students of Lepidoptera, and the specimens command a high price. It is not so large as the Papilio antimachus of Sierra Leone, but it enjoys the distinction of being the prettiest butterfly in America. A goodly number of swifts and large swallows were also in the collection. Gundlach made other journeys to the eastern province in 1885 and 1887, always collecting, always active and untiring, as if his seventy-six years, in spite of the arduous nature of his enterprises, had dealt lightly with him.
His unrivaled Cuban Museum established in the Havana Institute, still claimed and received his attention to the last moment of his working life. A hearty octogenarian, he continued to devote himself, as with his old-time energy, to improving it as far as possible. Assisted by kind friends, he went up daily to his place of work, first assiduously laboring and then recreating himself with his only treasure. Finally, in 1896, the end came. He was taken from the institute to his deathbed.
Gundlach's researches in Cuban fauna are so numerous that it would be extremely diflicult to record them all in a brief summary. He first published Contributions to Cuban Ornithology, 1854-1857. Then followed, in quick succession, Index generum Coleopterum, 1854; Molluscorum species Novæ, 1858; A Synoptic Conspectus of all the Birds observed in Cuba, published in the Journal für Ornithologie, 1861; A Review and Catalogue of the Cuban Birds, 1865; A Review and Catalogue of the Cuban Reptiles, 1867; New Contributions to Cuban Ornithology, in the Journal für Ornithologie, 1871, 1872, 1874, 1875; Contribution to Cuban Ornithology, 1871, 1876; Contribution to the Ornithology of Porto Rico, 1874; Contribution to Cuban Mammalogy, 1877, 1878; Notes on the Fauna of Porto Rico, 1878; New Contributions to the Ornithology of Porto Rico, 1878; Contributions to Cuban Herpetology, 1880; Contributions to Cuban Entomology, 1881; Land and River Mollusks, 1883; Sea Mollusks, 1883; besides descriptions of new species of mammals, birds, reptiles, and insects, published in journals, organs of learned societies, etc. Gundlach was also distinguished by his skill, grace, and delicacy as a taxidermist, the wonderful patience with which he performed every branch of that work, and the gift of genius by which he was able to give a startlingly natural pose to the specimens he mounted.
The list of honors which Gundlach received from institutions and learned societies is a long one. In 1853 he was made a corresponding member of the Natural History Society of Montreal,
