The latter has twenty-two rings on the trunk and five on the tail. 
The number of ventral plates is 221, of the caudal 39. The black 
rings are equidistant. Each ring is narrowly edged with yellow, the 
ground colour is dark blood-red, browner on the upper surface, which 
grows darker towards the centre of the back. The first ring com- 
mences anteriorly within the posterior angles of the occipital shields. 
Each black ring includes a series of six scales, and each interval be- 
tween the rings mostly includes fourteen scales. 
ELAPS FULVIUS. 
_ At Lanquin I obtained three specimens of a snake of this genus, 
which appears to be the Z. agl@ope, Cope. The ground colour of 
all these is red, darkest on the centre of the back, and the character 
of the markings is the same. They, however, differ in some respects ; 
and I therefore describe each fully, though without the slightest 
doubt they belong to the same variety. 
No. 1 has forty-one black rings on the trunk and ten on the tail. 
Between each ring on the trunk is a series of black spots, more or 
less run together or isolated, and arranged so as to form an irregular 
line on the upper surface parallel to the rings. On the tail these 
intermediate markings do not exist. The ring on the neck passes over 
the head across the posterior margin of the occipital shields in an 
irregular line, converging anteriorly. A band of black crosses the 
head, and passing over the posterior frontal and vertical shields con- 
verges posteriorly. The rostral and anterior frontal shields are dark 
reddish-brown. The rings are interrupted in several cases on the 
belly. The rings include a series of four scales, and the intervals 
between the bands a series of six. The number of ventral plates is 
207, of caudal 51. 
No. 2 is coloured exactly as the preceding; but the rings are less fre- 
quently interrupted, and the intermediate markings assume more deci- 
dedly the form of a ring. The black rings are forty-five in number on 
the trunk, and nine on the tail. The ring round the neck passes be- 
hind the occipital shield, but has a square marking extending partially 
over those shields ; a marking passes over the frontal superciliary and 
vertical shields, but not quite to the lower margin of the labials. 
The black rings include a series of three scales, and the intermediate 
spaces six. The number of ventral plates is 224, of candal 40. 
No. 3. The rings of this specimen are very much interrupted, and 
the intermediate markings very irregular. The number of rings is 
forty-three on the trunk, and on the tail twelve. _The ring round 
the neck is the same as in the other specimens, having its anterior 
edge passing over the occipital shields in an irregular line. The 
marking on the anterior part of the head extends to the lower labials. 
The rings include three scales, and the intervals between the rings 
five ; these, however, vary much. The number of ventral plates is 
212, of caudal 55. 
It certainly appears somewhat remarkable that I should have found 
the northern form £. fulvius in the hot district of Lanquin, and the 
southern £. corallinus at Duenas, in the temperate region of the
