Dromicus cursor, var. pleii. 

 Dromicus pleii D. & B. 



Martinique, in the low-lands near Fort de France. Rows 17 ; veutrals 

 195, 193, 192, 190 ; anal bifid ; subcaudals 107, 104, 101 pairs. 



These specimens are much lighter-colored than those from the heights ; 

 the colors are more olivaceous, and the bands are as in the original 

 description. 



Dromicus cubensis, nom. sp. n. 



Cuba. This is the D. cursor of Bibron, but not of LaCepede. Rows 

 17 ; ventrals 149, 145, 145, 142, 140 ; anal bifid ; subcaudals 87, 92, 94, 106 

 pairs. Near the base of the tail some of the scales bear two pores ; far- 

 ther forward but one may be discovered, and anteriorly they become 

 obsolete. 



Dromicus jult^ Cope, sp. 



Dominica. Rows 17 ; one pore ; veutrals 157, 161, 162 ; anal bifid ; 

 subcaudals 77, 84 pairs. 



On a variety of this species fuund in Marie Galante the marks are not 

 so black as on those from Dominica. Instead of a bright yellow spot 

 near the middle of the scale, the lighter portion is more olive and the col- 

 oring is more irregularly placed. Ventrals 161, 164 ; subcaudals 82, 81 

 pairs. 



Dromicus ornatcs, sp. n. 



St. Lucia. Roves 17 ; one pore ; ventrals 190, four 191 each, 194 ; anal 

 bifid ; subcaudals 86, 85, 88, 86, 91 pairs. 



This handsome serpent is much like the Couresse of Martinique. Its 

 tail appears to be a trifle shorter ; its colors distinguish it very readily. 

 From nock to end of tail it has a median band of brown, which on the 

 body is about six scales wide and which contains two rows of round or 

 squarish spots of white larger than a single scale and separated from each 

 other by spaces of like width. On the third row there is a dark stripe in 

 which the scales are marked with a yellow spot. The anterior edges of 

 the ventrals are black. A black band behind the eye ; a yellow spot on 

 the lateral edge of each parietal ; two or three transverse yellow streaks 

 on the snout. Ground color of labials and lower surface yellowish or 

 white. D. cursor has a white vitta at each side of a black band of five 

 or six scales in width ; anteriorly the vitta is more or less broken into 

 spots but the included band lacks the two series of spots. 



Dromicus temporalis Cope. 



This appears to be the species figured by Jan and Sordelll under the name 

 of D. nuntlus. The specimen which served as type of D. temporalis has 

 the locality Cuba. It has seventeen rows ; pores not visible ; ventrals 

 166 ; anal bifid ; loreal and anteorbital fused on both sides.
