Color emerald-green, with a broad brown band from the orbit to the middle of 

 the side, and a narrower one on each side of the sacrum. A green band from 

 orbit to below tympanum, and a dark-brown band from orbit below the canthus 

 rostralis. A dark-brown cross-band between the superciliary borders across the 

 ' front. A deep brown spot behind the occiput, and a smaller one on the nape^ 

 Femur with a longitudinal black band behind, and an oblique one across the supe- 

 rior face. Tibia and forearm with a broad cross-band. 



From the slope of the Pico Blanco ; elevation not known. 



A species markedly distinct in many respects, approaching the A. scyphaus in 

 its few small supraocular scales. 



54. Anolis oxylophus, Cope, spec. nov. 



A species above medium size of the group with keeled ventral scales and without 

 caudal crest or serra. The dorsal scales are distinctly larger than the lateral and 

 about equal to the ventral. They are flat, subhexagonal, not imbricate, and have 

 a median keel. There are at least twenty rows of equal size, those exterior to 

 them graduating in size to the laterals. The scales of the upper surface of the 

 head are very small, but flat, seven rows separating the rugal, and two the super- 

 ciliary scuta. Small scales separate the rugal and canthal scuta. Occipital scute 

 of moderate size, bounded laterally and in front by a number of scuta of the same 

 size and form. Supraorbital disk composed of two rows of slightly keeled scuta 

 with some small ones adjacent. Ten rows of loreals ; 13-12 labials, Infralabials 

 all very small and carinate. The canthus rostralis is distinct to near nostril. The 

 facial ruga is remarkably prominent and acute, but not extending beyond the 

 middle of the canthus. Auricular opening about one-fourth as long as the eye 

 diameter. The form of the head is regular, and of good proportions; it is as long
