4 oL. G. ANDERSSON, CATAL. OF LINNEAN TYPE-SPECIMENS OF SNAKES. 
for which reason these specimens in general have been easily 
distinguished. According to S. LovÉn it was not LINN2US who 
labeled the objects in the museum in question, but Ö. SCHWARTZ, 
Director of the museum of the R. Academy of science from 
1806 to 1819, and already in 1789 commissioned to take 
charge of the collections in question. ÅS SCHWARTZ Was a 
botanist and not a zoologist, it is possible that the mistakes 
in the thicketing which in some cases probably are made 
may date from his time. 
The snakes from Mus. DE GEER are all in want of any 
significant label, but from the older collections there is in the 
R. Museum usually only one specimen of these types, which 
specimens always completely agree with LINNAZUS'S diagnoses 
in Systema Nature. Therefore, it was easy to distinguish 
also these types. 
Linnaeus has described 71 species from Mus. Ad. Frid., 
57 in his first part and 14 in his second, arranged under 
his well-known 6 genera, Coecilia (2 species), Amphisbaena 
(2 species), Anguis (3 species), Coluber (61 species), Boas 
(2 species), and Crotalus (1 species). In the 12:th edition of 
Systema Nature he gives 8 species (6 Coluber and 2 Boa) 
from Mus. DE GEER. 
To judge from the manuscript catalogues of 1802 and . 
1808 of the collections of the R. Acad. of Sc., two of the 
types in the Mus. Ad. Frid. had been lost before its removal 
to the Academy, viz., Coluber Tyria, and Coluber libetinus, 
both obtained by HasseLovist during his »Iter Palzestinum:. 
But these catalogues do not seem to be very trustworthy. 
They differ considerably, especially in regard to the number 
of the specimens of each species, in which they both further 
differ from a catalogue, showing the actual state of the 
collection. At present are the specimens of a species often 
fewer than stated in these catalogues. If this only was 
the case, we might suppose that the missing ones had been 
lost, but frequently there are more specimens of a species 
than stated, and then we must presume that there are mis- 
takes in the catalogues 'or else that other Linnean type- 
specimens have been found since the catalogues were drawn up. 
From my revision it appears that of LINN2Zu$'s 71 types 
described in Mus. Ad. Frid. at present only 55 remain. The 
authenticity of two of these, Coluber cobella and Coluber
