Snakes and Lizards of Jamaica. 423 
it wents the dorsal spots. They are both females; the first mentioned 
one appears to be a Drassus, Walckenaer and Latreille. There is also in 
that phial a third Spider, very minute, resplendent with silver dots. 
In a large bottle, together with 1. the olivaceous-brown Snake of this 
Island, I send, 2. a snake from Cape Gracias a Dios, in which the dorsal 
scalesare generally pied, the anterior portion being more or less white, 
and the posterior black; and 3. another Snake from Carthagena, called 
there by some name answering to our term of ‘ Barber’s pole,” though 
I cannot guess why. Its black scales however are yet more curiously 
marked towards their base by a yellowish subeliiptical spot along the 
middle with a white line diverging from it on each side; and 4thly. a 
specimen of what they here term * the double-headed Snake,”? which is 
perhaps what Shaw has called Anguis Jamaicensis (Gen. Zoology, 
v. 3, p. 488.), ‘A. subargenteo-fuscescens,”’? although in this indivi- 
dual I can discern no silvery hue, and but a very faint resemblance to 
his figure of it: still less does it correspend with Dr. Pat. Browne’s de- 
scription and figure of Anguis lumbricalis. Tome it appears to fall 
under Schneider’s sub-genus Typhlops, and its form, its caudal aculeus, 
and some other peculiarities render it interesting, especially as the 
notions concerning the Angues (Linn.) have been loose and erroneous. 
It is a pretty creature, and will, I hope, deserve to be figured. Besides 
these Ophidians I send some number of different Saurian Reptiles, of 
which I will here only notice the three largest, viz. 1. Ameiva vulgaris, 
of which Shaw has given but an indifferent figure. I never sawa live 
one except at a distance in the bushes, else I would describe its hues, 
which are handsome, and cannot well be understood from a specimen 
in spirits. 2. A noble looking animal caught in the parish of Man- 
chester, about the centre of Jamaica, and there cailed the green Lizard; 
and 3dly. another with a broad black stripe extending from the eye to 
the hind leg and bordered on each side with a narrow whitish stripe: 
this is supposed to assist the Snakes as an indicator of prey, and has 
thence obtained the name of the Snake's Waiting-boy. There are many 
other Lizards, of various sub-genera, some of them very diminutive; and 
of the whole I helieve that the first mentioned is the only one that has been
