SjKikes (Hid Lizards <f Jamaica. 423 



it wants 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 

 scales are 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 gness why. Its black scales however are yet more curiously 

 marked towards their base by a yellowish subelliptical spot along the 

 middle with a white line diverging from it on each side; and 4thly. a 

 specimen of what they here term " thedouble-lieaded Snake," which is 

 perhaps what Shaw has called ^'^iiguis Jamaicensis {Gen. Zoology, 

 v. 3, p. 588.), " 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 ./^?i(/in5 himhricalis. 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 .Ungues (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. ..^meiva vulgaris, 

 of which Shaw has given but an indifferent figure. I never saw a 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 called 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 nan)e of the Snake's IFaiting-boy . There are many 

 other Lizards, of various sub-genera, some of them very diminutive; and 

 of the whole I believe that the first mentioned is the only one that has been
