for his letter [Tessin to Linnaeus, 27 November 1755Letter L1967].

Linnaeus comments on Tessinís plans to write about Nummus Brattenburgensis and states that it can be found in fossils in Skåne. Franciscus Ernst BrückmannBrückmann, Franciscus Ernst

collector. Physician at Helmstädt,

has got a pair in Germany but Linnaeus does not know if anybody has fetched them. Nobody has seen them alive, although they belong to the turtle family and are now classified as inter deperditos.

Linnaeus thought he was the only owner in the world of both shells; Nummus Brattenburgensis, like Pectines, has two different shells, one is conical and the other the ordinary Nummus Brattenburgensis.

Linnaeus asks Tessin to ask the following questions if he writes to England:


1. If this Nummus Brattenburgensis in the corals was an original or a fossil? In the latter case it is not so unusual.
2. If this Nummus Brattenburgensis has its two shells.
3. If this is the case, please ask for more details about the second shell or a drawing. Maybe the whole thing is a fake as can already be found in His Majestyís [Adolf FredrikAdolf Fredrik, (1710-1771).

] collection of corals. If the two shells are alike the whole thing is wrong.

Linnaeus informs Tessin that he has the second shell in Fauna SvecicaLinnaeus, Carl Fauna Svecica

Linnaeus praises Tessin for his contribution to science.
