ON THE REPTILIA OF PERU. 



167 



specimens in the museum of the Jardin des Plantes, One of these is the A. coe- 

 lesti7ius, Cope; for the other the name A. chlorocyaneus must be retained. Both 

 A. pentaprion and A. vittigerus are abundantly distinct from the familiar A. bipor- 

 catiis of Mexico ; and A. hitectus and A. ordinatus are, I think, outside the range 

 of variation of the species to which Mr. O'Shaughnessy refers them, though nearly 

 allied. Anolis spectrum. Pet., is distinct from A. cymiopleurus, Cope. 



16. Anolis ortonii, Cope, Proceed. Acad. Philada. 1868, p. 91. 



From Nauta. One of the specimens is brilliant golden, with green reflections. 



n. Anolis booourtit, Cope, sp. nov. 



Allied to the preceding, and to the A. trochilus and A. bransfordii. Cope. The 

 abdominal scales are small, flat, and smooth ; the dorsals are smaller and thickened, 

 but not keeled, and the laterals are a little smaller still, and subgranular. They 

 graduate into the dorsals and ventrals. The tail is slightly compressed,. but has 

 no median keel. The head is elongate, exceeding the length of the tibia ; the 

 muzzle is longer than it is wide at the anterior margin of the orbits. Occipital 

 scute small, a little exceeding the auricular meatus, and separated from the super- 

 ciliaries by numerous flat scales. The superciliary scales separated by two or three 

 rows of small scales. The facial rugse are very obtuse, and are separated by a 

 shallow concavity. The latter is floored with smooth scales, which are much 

 smaller than those of the rugge, a transverse line crossing eight of them. The 

 scales of the front of the muzzle are larger, and twelve rows without keels may 

 be counted between the canthal series. Supraorbitals few, surrounded by granules ; 

 consisting of one hexagonal smooth plate, surrounded, except on the inner side, 

 by five similar or smaller ones. Seven loreal rows ; labials 8-9 ; infralabials sub- 

 equal, small, smooth, and in four rows. Auricular meatus half the size of the 

 eye-slit. Fan large. The fore limb reaches the end of the muzzle, but the hind 



limb only reaches the front of the orbit.
