Coluber Aheetulla. 
Described by LInnzaus in Amoen. Acad. Tom I, N:o V, p. 115, N:o 2 
and N:o XVI, p. 495, N:o 12; Mus. Ad. Frid. I, p. 35, ta05 2eygigNes 
Syst Nat. Ed. X, p. 225, Ed. XII, p. 387. 
Syn. according to Bour. Cat. Sn. II, p. 79, Dendrophis pictus. 
In the Royal Museum there are three specimens from 
Mus. Drottn., labeled Coluber Ahetulla. One of these snakes 
is identical with Dendrophis pictus (GMEL.) Borr, the two 
others are Leptophis liocercus (Wi1ED.) Dum. & BIBR. 
From the description of Coluber Aheetulla in Mus. Ad. 
Frid. it is evident that the former was the type used by 
LINNAEUS. DLÖNNBERG,! however, has shown that LINNZUS'S 
type-specimens for the descriptions in the two above quoted 
Amoen. acad. were Leptophis liocercus, wherefore he thinks 
that this snake ought to be named Aheetulla, as it is by 
some authors. In the 10:th edition of Syst. Nat., from the 
publication of which we reckon the initiation of the bino- 
menclature, LINNEUS refers to the descriptions of Col. Ahee- 
tulla both in Amoen. acad. and in Mus. Ad. Frid. The number 
of the shields he gives in Syst. Nat. is that which we find 
in Lept. liocercus, for which reason it is probably most cor- 
rect to give the name Aheetulla to this one, and to let Den- 
drophis pictus retain its name, given by GMELIN.
