Cope.] ^70 [June 20, 



concave. Occipitals short and wide for the genus ; each is hounded pos- 

 teriorly hy a single large temporal plate behind the anterior one on each 

 side, which are only separated on the median line by a small scale. 



The ground color in spirits is straw-color. The dorsal region, between 

 the fourth row of scales on each side, is occupied by a series of large 

 rounded brown spots, whose borders are almost in contact on the median 

 line. There are forty-two between the nape and the vent. Occasionally 

 two or more of them are confluent on the middle line. Below and between 

 them the sides are brown shaded, the shade assuming the form of spots 

 anteriorly. Head brown, with a pale spot on each side of the nape ; a 

 brown spot with darker borders passes from the muzzle through the eye, 

 and joins the brown dorsal spot on the nape. All the colors become darker 

 posteriorly. Inferior surface unspotted anteriorly; it is sparsely dusted 

 with brown on the posterior half of the body, and the caudal scutella are 

 dusted most densely along the middle line, forming a stripe.

Amiva surinamensis tobaganus, sub-sp. nov. 



A single Amiva from Tobago forms a strongly marked race of the com- 

 mon continental species, but whether separable as a species or not I am not 

 yet able to state. It differs from the typical A. stirinamensis in color, in 

 a disposition to a somewhat greater subdivision of the scuta of the limbs 

 and belly, and in the greater length of the posterior foot. There are twelve 

 rows of abdominal scales at the middle, as is sometimes seen in A. suri- 

 namensis. The two inner rows of antebrachials extend to the wrist ; only 

 one row extends so far in A. surinamensis. Both brachial and postbrachial 

 scales, as well as those of the gular fold are rather more numerous than in 

 A. surinamnesis. In the latter species the length of the posterior foot 

 equals the distance from the axilla to the middle of the loreal plate ; in the 

 form tobaganus the foot is as long as from the axilla to the end of the 

 muzzle. 



Color olivaceous, with a black lateral band with undulating edges, which 

 are not light bordered, but which are marked by small yellow spots at 

 regular distances. Back with a chain-like series of black annuli on each 

 side, each ring with an obscure yellow spot in its center. Sides black and 

 yellow-spotted ; below uniform straw-colored ; head uniform brown, lips 

 lighter. 



No. 10113 ; size less than that of the adult A. surinamensis. 



Anolis alligator D. and B. 



Drymobius boddcertii Seetzen. 



Bothrojis lanceolatus Merr. (Fer de lance.) 



Scales in thirty-one and thirty-three longitudinal rows ; colors pale, with 

 the cross bands obscure, as in other West Indian specimens. 



Ilylodes martinicensis D. and B. No. 10121. 



The Island of Tobago is, of the Lesser Antilles, the nearest to Trinidad,
