34 OL. G. ANDERSSON, CATAL. OF LINNEAN TYPE-SPECIMENS OF SNAKES. 
Coluber Alidras. 
Described by LINN=US in Syst. Nat. Ed. X, p. 217, Ed. XII, p. 376. 
This Linnean type is not identified by the authors. It 
is a completely discoloured specimen of Helicops angulatus (L.) 
Dum. & BiBR., from which it however differs by 21 rows of 
scales on the thickest part of the body instead of 19. 
Thus, LInNN2av8's Coluber Alidras is synonymous with his 
Coluber angulatus. 
One specimen. 
Total length 720 mm. Tail 165 mm.!  Sq. 21. V. 121. GC. 58! 
Coluber monilis. 
Described by LInNNn2aus in Syst. Nat. Ed. X, p. 221, Ed. XII, p. 381. 
In the Royal Museum there are four snakes, called Coluber 
monilis L. Of these one agrees completely with LINNZUS'S 
description, and it is very probable that this one was LIN- 
NAUS'S type. It is a Homalopsis buccata (1L.) SCHLEG. 
Total length 245 mm. Tail 65 mm. Sq. 39. V. 164. C. 82. 
Coluber niveus. 
Described by LINNZUS in Syst. Nat. Ed. X. p. 223, Ed. XII, p. 384. 
There is in the Royal Museum one snake, called Coluber 
mveus LDL. It is evidently the Linnean type-specimen. In his 
Catalogue of Snakes III, p. 374 BouLENGER considers Coluber 
mveus L. as a synonym to Coluber Haje L. This is however 
a mistake. I am now able to state that LiInnazus's Col. ni- 
veus is synonymous with Naia flava (MERrRR.) Bour., which 
snake therefore should be called Naia nivea (L.). 
Total length 975 mm. Tail 165 mm. Sq. 21 V. 209. OC. 62. 
Coluber Pelias. 
Described by LInN2aus in Syst. Nat. Ed. X, p. 224, Ed. XII, p. 386. 
This Linnean type is not identified by the authors. It 
is a OUhrysopelea chrysochlora (REINW.) BourL., the name of 
which therefore should be Chrysochlora Pelias (L.). 
One specimen from Mus. de Geer. 
Total length 975 mm. Tail 165 mm. Sq. 17. V. 187. dC. 103. 
! The tail is somewhat mutilated.
