26 LL. G. ANDERSSON, CATAL. OF LINNEAN TYPE-SPECIMENS OF SNAKES. 
Coluber coerulescens. 
Described by Linnaus in Mus. Ad. Frid. I, p. 37, tab. 20, fig. 2, 
Syst. Nat. Ed. X, p. 227, Ed. XII, p. 389. 
Owing to the incompleteness of the description, given by 
LINNEvs, this type could not be identified by the authors. 
From Mus. Drottningh. there is one specimen, marked Colu- 
ber coerulescens. "This is a Herpetodryas fuscus (L.) Bour. In 
the number of shields the specimen differs very much from 
what LINnNAEUvS states. This has 155 + 115 shields, that of 
LINNEUS 215 + 170, and of the bright blue colour mentioned 
by him nothing is visible except on the lower part of the 
head. Consequently it is hardly probable that this specimen 
was the type of Linnzus's Coluber coerulescens. According 
to QUuENSEL's catalogue of 1802 there were at that time five 
specimens from Mus. Drottn., which were said to be Coluber 
coerulescens L. One of the four which are now lost was 
probably LInNäus's type-specimen. Whether LINNZus named 
this specimen Col. coerulescens, or whether this is only an 
incorrect conjecture of ScHWARTZ is impossible to say. 
Total length 520 mm. Tail 165 mm. Sq. 10. V. 155. C. 115. 
Coluber hortulanus. 
Described by Linn=us in Mus. Ad. Frid. I, p. 37, Syst. Nat. (named 
Boa hortulana) Ed. X, p. 215, Ed. XII, p. 374. 
A jar from Mus. Drottn., labeled »Boa hortulana», con- 
tains a specimen of Himantodes cenchria (L.) CoPE; but it 
certainly is not the type of Linnzus's Coluber hortulanus. 
It is possible, however, that he regarded it as being a young- 
one of this snake, as the colour of this specimen corresponds 
somewhat with that of Boa (Coluber) hortulana; but it is 
also possible that, by some accident, the labels have been 
changed. 
Total length 600 mm. Tail 190 mm. Sq. 17. V. 259. C. 166. 
Boas Constrictor. 
Described by LInnzaUus in Amoen. Acad. Tom I, N:o XVI, p. 497, N:o 16, 
tab. 17, fig. 3, Mus. Ad. Frid. I, p. 38, Syst. Nat. (Boa constrictor) Ed. X, 
p: 215; ET. IX. p. oro 
Syn. in Bour. Cat. Sn. I, p. 117, Boa constrietor L.
