上部头鳞小，钝龙骨状;鼻状的从喙分开;没有大的suproeulars;顶骨破碎。颈部两侧不弯曲，覆盖着尖状，覆瓦状，龙骨状的鳞片。发达的背嵴背鳞大，短尖，强烈龙骨状，龙骨状形成直的纵向线;小的一样大;腹面有点小，平滑; 45鳞片围绕身体的中间。几乎和背一样大的胶鳞。后肢向前伸展，到达耳朵或眼睛。尾巴无力地压扁，只在基部有羽冠。上面淡褐色，背部有黑色的人字形斑纹，向后指，两侧有小黑点;前肢上方有一个或多或少明显的黑色和白色斑点或单眼;侧膜和眼下区奶油色，口缘黑色;喉区奶油色，有黑色条纹，中间有一个黑色斑点，然后是一个粉红色斑点;一条黑色条纹横跨胸部，与一条黑色条纹沿着腹部中线汇合，在前肛区加宽，并在后肢下延续;腹部两侧粉红色。这些腹部的标记在年轻时没有。全长232毫米。从口鼻部到排气口87;头部20;头部宽度14;前肢B4;后肢56。四个样本来自奥菲亚，6500英尺。我利用这个机会观察到，西蒙斯先生收藏的蜥蜴最近被我描述为Ameiva leucostigma（[9]。ZS 1899，p. 517，pl. xxviii.）为Cnemidophorus，与C.雀斑样痣G型臂（Bull.埃塞克斯研究所。1892年，第92页），正如我的朋友佩拉卡伯爵向我指出的。吻部凹陷~突出，方形截形，与眼睛等长，有角状的前眦和垂直的虹膜区域;鼻孔比眼睛更靠近吻部的末端;眶间隙比上眼睑更宽;鼓膜完全清晰，其最大直径是眼睛的三分之二。第一个手指不延伸超过第二个;脚趾游离/末端盘和手指和脚趾的关节下结节相当小;跖骨结节小。当后肢向前伸展时，肋骨和跗关节到达眼睛。皮肤光滑柠檬黄色;一条黑色的侧带~从吻部末端到腹股沟，穿过眼睛和鼓膜;另一条或多或少
Upper head-scales small, obtusely keeled; nasal separated fi'om the rostral; no large supraoeulars; parietals broken up. Sides of neck not plicate, covered with-pointed, imbricate, keeled scales. A well-developed dorsal crest. Dorsal scales large, mucronate, strongly keeled, the keels forming straight longitudinal lines; laterals quite as large; ventrals a little smaller, smooth; 45 scales round the middle of the body. Gular scales nearly as large as dorsals. The hind limb, stretched forwards, reaches the ear or the eye. Tail feebly compressed, crested at the base only. Pale brown above, with black chevron-shaped markings, pointing backwards, across the back; sides with small black spots; a more or less marked black and white spot or ocellus above the fore limb; loreal and subocular region cream-colour, the edge of the mouth black; gular region cream-colour, streaked with blackish, with a median black patch followed by a pink one; a black bar across the pectoral region, confluent with a black stripe along the middle line of the belly, widening on the pr~ eanal region and continued under the hind limbs; sides of belly pink. These ventral markings absent in the young. Total length 232 millim.; from snout to vent 87; head 20; width of head 14; fore limb B4; hind limb 56. Four specimens from Ofia, 6500 feet. I avail myself of this opportunity to observe that the lizard from Mr. Simons's collection recently described by me as Ameiva leucostigma ([9. ZS 1899, p. 517, pl. xxviii.) is a Cnemidophorus, and is identical with C. lentiginosus, G-arm.(Bull. Essex Inst. xxiv. 1892, p. 92), as pointed out to me by my friend Count Peracca. t) rostherap [s tricolor.Snout depressed~ projecting, squarely truncate, as long as the eye, with angular canthus rostralis and vertical loreal region; nostril nearer the end of the snout than the eye; interorbital space broader than the upper eyelid; tympanum perfectly distinct, its greatest diameter two thirds that of the eye. First finger not extending beyond second; toes free/terminal disks and subarticular tubercles of fingers and toes rather small; t~ o small metatarsal tubercles. The rib; otarsal articulation reaches the eye when the hind limb is stretched ibrwards. Skin smooth. Lemon-yellow; a black lateral band~ from the end of the snout to the groin, passing through the eye and the tympanum; another more or less
