IL the Royal Museum in Stockholm are preserved the most 
of the type-specimens of LINN2ZUS'S »Serpentes». Most of these 
came from Museum Adolphi Friderici regis and are described 
by LINN2vs in the two parts of his work on this museum.! 
The first part, which is much the larger of the two — the 
great volume, in folio, with excellent figures — was published 
in 1754: the second part, however, though finished that same 
year, was not published till ten years later, owing to the 
troubled times at court, when it appeared, together with 
the description of Museum Ludovice Ulrice, like which it 
also is a Prodromus and without figures. 
When Gustaf IV Adolf in 1801 divided the collections 
of his grandparents between the University of Upsala and 
the R. Academy of Science in Stockholm, the snakes came 
among other things to Stockholm. Besides these specimens 
from Mus. Ad. Frid., there are in the R. Museum a few 
other Linnean type-specimens of snakes. These came from 
the museum of the court Marshal, CARL DE GEER, at Löfsta 
in Upland, and are characterized by LInnzvus, but only in 
Systema Naturze. After CARL DE GEER's death in 1778 his 
widow presented the greater part of his collections to the 
R. Academy of Science. 
At the request of the Director of the Vertebrate Depart- 
ment of the R. Mus., Professor F. A. Smitt, I have revised 
these Linnean type-specimens. 'The result of my work is 
given in this paper. 
The Linnean specimens from Mus. Ad. Frid. are marked 
with small rectangular labels with printed Linnean names, 
"In a paper >On the species of Echinoidea described by Linneus 
in lus work ”Musewn Ludovice Ulrice”» in K. V. A. Handl., Bihanget, 
Band 13, Afd. IV, 1588, S. LovÉnN gives an interesting account of the origin 
of this museum, as also of that of Queen Lovisa Ulrika, and of LInNmUs'S 
Work in both of these.
