Museum said to be from "AuguiHa Eock, near Trinidad." It 

 appears, from Dr. Yan Rijgersraa's investigations, that the Island 

 of Anguilla, far north of Trinidad, was meant. 



Anolis leachii, Gray. 



This species is near the last, but has coarser lateral scales and 

 more slender mandible ; it is also larger, and the color is quite 

 different. It is bright green with a pale band over the shoulder, 

 with a black spot aboA-e it, opposite the axilla. The fan is small. 



AMIVA ERYTHROPS, Rijgersma, MS., sp. nov. 



Abdominal plates in 12-14 series; no spurs on the heel. One 

 frontal, four supraorbital, nine superciliary plates. Five infra- 

 labials separated by a few intermedials from posterior labials, first 

 not separated from third labial. Seven rows of larger gular scales 

 extending entirely across the throat. Three larger series on gular 

 fold, which has several rows of granules near margin. Brachials 

 small, in four rows ; postbrachials small. Antebrachials large, 

 two rows hexagonal, one transverse. Femoral pores small, 38 in 

 a series. Preanal scales two large median with a single row of 

 one or two in front ; small scales occur in some specimens behind 

 the posterior two. Outer hind toe a little longer than inner. 



Teeth in adults compressed, one or two only with denticula- 

 tions. The end of the longest toe of the extended hind foot 

 reaches the anterior margin of the ear. 



Color brownish-olive, with a broad greenish band on each side 

 the back from the nape above the ear. In young specimens these 

 bands are bright. Another less distinct band extends along the 

 side from above axilla to groin. Between these and the dorsals, 

 and across the back, are transverse black reticulations. Bellj' 

 greenish, the color appearing as spots on the outer scales. Tho- 

 rax and edge of sides of fold black ; throat bright yellow ; sides 

 of head red ; upper surface brown ; limbs olive, with black reticu- 

 lation.
