OIS" THE PHYSIOaXOMY OE SERPENTS. 
2. CALxiMARiA Linn^i, from the island of Java, resem- 
bles the preceding in form, and in the disposition of the 
plates of the head and the scales of the trunk ; but its body 
is less thread-like and scarcely exceeds a foot in length. 
The colours are not less subject to variation than the length 
of the tail. The lower parts are often of a vermilion-red, 
ornamented with large, square, black spots. Plates or 
scuta 130 + 90 to 160 + 20. 
3. Calamaria Orbignyi of Chile appears to represent 
in the New World the Cal. Lumbricoidea, of which it has 
the shape and appearance; but its neck has. 15 rows of scales, 
and all its parts are smaller. Above it is of a burning 
brick-red, the lower parts of a pearly lustre. The top of 
the head, a spot on the nape, and a band on the tail, are 
deep black. S. 264 + 30. 
4. Calamaria amcena is found in North America, and 
corresponds in size and form to Cal. Linnsei of the East 
Indies ; its mould, how^ever, is more slender, and the ab- 
dominal scuta, as well as the nasal plates, are a little 
broader. Above a shining brown, below red. The mean 
number of scuta 120 + 30. 
The following species recede more or less from the pre- 
ceding, which form the type of the genus : 
5. Calamaria Diadem a, the only one known in New 
Holland, presents exactly the form of the preceding ; but 
we only find on it two pairs of frontal plates. It is of a 
pale yellowish-brown, clearer below, with transverse spots 
of vfhite on the occiput. S. 170 + 45. 13 rows of scales. 
6. Calamaria Brachyorrhos is found in the isles of 
Java and Amboina, and has the same number of plates on 
the head as the last ; but it has a stouter make than the 
typical species, a trunk more thick and tapering towards 
each end, a head very conical. Of a dull uniform brown, 
passing into yellowish below ; 17 rows of scales. S. 138 + 
13 to 180 + 38. 
7. Calamaria Badia of Cayenne, with a less vigorous 
mould and smaller size. It has the general aspect of the 
last, but its tail is more slender, its head more obtuse, its 
eyes larger, and has a small frenal plate on each side. This 
species, clouded with brown and ochre-yellow, presents a
