Two brown bands on neck, thirty-two rows of scales nnimarginata. 



c c. Frontal truncate anteriorly. 



Scale slarge s'urinamensis. * 



C. Eye over fifth superior labial. 



Thirty-four rows of scales, head acute aenea. f 



Thirty rows of scales. 

 Elongate ; head acute ; appressed extremities not touch- 

 ing lanceolata. 



Stout; head short; appressed extremities meeting cepedii. t 



Mabuia fulgida is perhaps the most abundant species in Jamaica, where 

 it has been seen and described by Mr. Gosse under the name of M. a g i 1 i s. 

 That the agilis of Dr. Gray is this species is not improbable, though that au- 

 thor has alluded to South American specimens, and quoted synonymy per- 

 taining to the South American species, the original agilis, which Girard's des- 

 cription shows to be distinct. 



The scales of the median nuchal rows are of unusual breadth. The head is 

 narrow, continuous with the neck, and the muzzle is depressed and acute. The 

 scales have a metallic refulgence, in fresh specimens strongly golden cupreous. 

 There are many small black spots on the dorsal region. The lateral stripe 

 extends from the end of the muzzle, and is black ; its yellow superior and in- 

 ferior borders are brightest anteriorly, the former extending round the muzzle, 

 and having a brown inner border. The tail is speckled with blackish brown, 

 .and the extremities are barred with the same ; lips and beneath yellowish. 

 Specimens probably exist in most of the larger museums. 

 Mabuia cuprescens. 



Body short, gradually tapering into the narrow acute head. Length of 

 muzzle from canthus of eye a little greater than width between anterior mar- 

 gins of orbits. Supranasals in contact over rostral. Frontonasal rhombic, 

 broader than long. Frontal not truncate, its greatest width three quarters its 

 length. Four supraoculars. Anterior border of interparietals angular: 

 parietals in contact posteriorly ; postparietals well developed. Superior 

 labials eight, six beneath eye ; with the seventh the largest. Scales smallest 

 on sides, in thirty-four rows. Seven marginal prenasals. Extremities touch- 

 ing when extended. Length from muzzle to vent 3 in. ; from vent to end of 

 tail 5 in. ; hinder limb 1 in. ; fore limb 9 lin. ; muzzle to ear 7 lin. Gen- 

 eral color above iridescent brown or coppery, darkest on the median six rows 

 of scales. A brown band extends from the muzzle to the groin, covering three 

 and a half scales on the neck, one and two halves on the side. It is bounded 

 above and beneath by broad gray bands, of which the superior shades into the 

 dorsal color, except where bounded above by a narrow brown band which is 

 most distinct on the nape, though it extends on the head-plates and is trace- 

 able on the back. The lower light band is margined inferiorly by a darker 

 shade, which becomes a band between the rictus and axilla. Tail pale gray : 

 beneath whitish. 



Hab. St. Thomas. From Mr. A. H. Ruse, a gentleman whose valuable 

 collections have been for some time adding much to our knowledge of the 

 zoology of the West Indies. 



A very pretty species resembling the aenea in form, and the number 

 of rows of its scales. It has four supraoculars instead of three, the frontalis 

 not truncate anteriorly, the eye rests upon the sixth not fifth superior labial. 

 The coloration is different. 



* Hallowell, Trans. Amer. Phil. Soc. 



t " Scinque (appele Anolis de terre et Mabouia dans les Antilles) Cuvier." 



X Eumeces mabuia Bum., Bibr., as Dr. Gray has pointed out. 



I have supposed a specimen from the Paris Museum labelled as Eumeces mabuia 

 from Marie Galante, to belong to the M. aenea, while new Grenadian and Trinidad 

 specimens have been referred to the cepedii.
