130 ON THE PHYSIOGNOMY OF SERPENTS. 



2. Calamaria LiNNiEi, froni 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 ^^^th large, square, black spots. Plates or 

 scuta 130 + 90 to 160 + 20. 



3. Calamaria Orbignyi of Chile appears to represent 

 in the New World tlie Cal. Lumbricoidea, of which it has 

 the shape and appearance; but its neck has,15 rows of scales, 

 and all its i)arts 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 a.mcexa is found in North America, and 

 corresponds in size and form to Cal. Linnau of the East 

 Indies ; its mould, however, 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 t^^^e of the genus : 



5. Calamaria Diadema, the only one known in New 

 PloUand, presents exactly the form of the preceding ; but 

 we only find on it two pairs of frontal plates. It is of a 

 pale yelloAvish-brown, clearer below, with transverse spots 

 of white 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 broAvn, 

 passing into yellowish below ; 17 rows of scales. S. 138 + 

 13 to 180 + 38. 



7. Calamaria Badia of Cayenne, vnth 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
