This Linnean type has not been identified by the authors. 
In the Royal Museum there is one specimen from Mus. Drottn., 
labeled Coluber cinereus. "This is a Rhadinea cobella (L.) Bour. 
Is is, however, very doubtful. whether this specimen is 
the one LINNEUS had as type for his Coluber cinereus. The 
number of the shbields stated by LIiNNZus (200 + 137) differs 
considerably from that of this specimen (156 + 54). LINNAZUS 
also states the rows of scales at 19 instead of 17. In other 
respects the description may be referred to this snake, and 
the figure shows in some respects a remarkable resemblance to 
this specimen, though the tail is rather too long. As the 
specimen is in a bad condition, LINNazus may have made a 
mistake in counting the scales and shields, or there has been 
an error in copying, so that it is possible after all that this 
specimen may be the true Linnean type, though there are 
some reasons against this. 
According to the catalogues of 1802 and 1808. there were 
then two specimens in the R. Museum. If this statement be 
correct, it is also possible that the other specimen, now lost, 
was the true type of Coluber cinereus.

From Mus. Drottn. there are two specimens in the R. 
Museum, labeled Coluber mucosus, of these one, which was 
evidently the type for LINN2us's description, 1s identical 
with Zamenis mucosus; the other is a discoloured specimen
