small, the third and fourth broader than long. Interparietals and 

 the single parietals, longer than the frontoparietals. Infralabials 

 eight; median gulars enlarged all the way across, graded; scales of 

 mesoptychium large, in two or three rows, no granules on the border. 

 Abdominal plates in eight rows ; large brachials in six rows, continu- 

 ous with brachials ; no postantebrachials. Six rows of femorals at 

 middle. Femoral pores nineteen. Preanal plates about a dozen in 

 a triangular patch continuous with the ventrals. Extended hind foot 

 reaches to orbit. 



Four white lines on each side, and a vertebral line. Spaces be- 

 tween first and second, and dorsally between fourths of opposite side, 

 greenish-gray; space between second and fourth, black. Head 

 paler; below greenish-white. Posterior limbs with four irregular 

 longitudinal lines; one anterior, two superior, and one posterior. 



Total length, 170 mm.; length to vent, 55 mm.; do. to collar, 

 19 mm.; length of fore liml), 20 mm.; do. of hind limb, 41 mm.; 

 do. of hind foot, 23 ram. 



This species resembles in general appearance the C deppci deppei,^ 

 but the scutellation is materially different. An important character 

 is the presence of four supraorbital plates, from the last of which a 

 fifth may be cut off. The parietals and interparietals are also rela- 

 tively longer than in that species. 



No. 216, San Mateo; found by Sen. Anastasio Alfaro, Director of 

 the Museo Nacional, to whom the species is dedicated. 



Celestus cyanochloris sp. nov. 



Scales in thirty- three longitudinal series all with about a dozen 

 longitudinal keels, and no prominent median keel, except on the tail, 

 beyond the base. The scales of the tail are roof-shaped, so that 

 the lateral edges run in open furrows, while the middle line is promi- 

 nent. The striations extend not only to the head, but the parietal 

 and interparietal plates are grooved and i-idged. The rostral and 

 symphyseal plates are of equal width. Two postnasals, two i)re- 

 loreals and two postloreals, one above the other in each pair. A 

 large preocular; two suboculars, the posterior elongate, and four 

 postoculars. Four external, and four internal supraorbitals. Parie- 

 tals wider than the triangular interparietal, each three times as large
