⁂ A descriptive catalogue of the specimens in the private collection of the author's father, Jan Frederik Gronovius.

"It is clear that the work is intended to make a contribution towards an improved systematic arrangement, as is suggested by the word 'Zoophylacium', which may be translated 'System of Nature'. Many new generic names are introduced with careful diagnoses, but the specific diagnoses are descriptive only and the species are indicated by numbers, with bibliographic references to contemporary authors such as Linnaeus, Seba, Poda, etc... The first part of the book, dated 1763, containing the mammals, reptiles, and fishes, is dedicated to Peter Collinson, an Englishman, who was a Fellow of the Royal Society of London. The second part, dated 1764, contains the insects, with the Crustacea included as 'Insecta Aptera'." (L.G. Higgens. The 'Zoophylacium...', published in Journ. Soc. Bibl. Nat. Hist. II, 6)

The final part, which is not included, is on molluscs and zoophytes, was published posthumously in 1781.
