riorly ; canthus rostralis elevated, little concave ; frontal concavity well-marked, 

 not contracted anteriorly. Eyes and ears large, orifice of latter one-half that 

 ef former. Nostrils lateral terminal. Loreal scales small, eight-rowed ; muz- 

 zle and front scales longer than broad, striate, and sometimes one-keeled, of 

 equal size, in nine longitudinal rows across middle of muzzle ; superciliaries 

 eight, a little broader than long, separated by three rows of scales. Supraor- 

 bital disc surrounded by smaller scales, and composed of six or seven elongate, 

 keeled scales. Occipital small, surrounded by small, equal, rough scales. In- 

 fralabials small, equal, numerous, keeled; antebrachial and prefemoral keeled 

 scales larger than abdominals. Laterals and dorsals small, graniform or cari- 

 nate ; two or three median rows a little larger, less than abdominals, strongly 

 keeled. Scales round base of tail equal, keeled, as large as antebrachial. Muz- 

 zle to ear \" 4 /// ; between temporal ridges 9'" ; muzzle to vent 3'' 9'". An- 

 terior extremity 2" 4"'. Groin to heel 2" Q'"; heel to end digit 2". 



Above bronze brown, the head browner, the tail redder ; below pale metallic 

 ferruginous with green reflections ; no regular or distinct lines or spots. 



One 9 specimen from Caraccas, with trace of gular fan, in Mus. Brit. 



**** Tail compressed, or with a crest of compressed vertebral scales ; ventrals carinate. 



Anolis ordinatus. 



Head broad, subacuminate, depressed at end of muzzle, from which point to 

 middle of marginal supraorbitals equal between two latter points. Canthus ros- 

 tralis a little convex. Only one large scale on frontal ruga in front of last su- 

 perciliary. Front and muzzle scales longer than broad, one-keeled, in regular 

 longitudinal series, not imbricate; six rows between nares, (lateral subterminal) 

 of which the four middle are equal ; five loreal rows, labials five or six. Only 

 one large infralabial. Occipital surrounded by small scales. Supraorbital disc 

 nearly or quite isolated, each scale keeled, as broad as long, three larger in inner ' 

 series. Auricular opening half ocular ; fan well developed. A slight dorsal 

 nuchal fold. Scales of the extremities keeled ; of femur largest, larger than 

 abdominal. A few dorsal scales gradually larger, especially two median, which 

 are weakly keeled. Tail much compressed ; scales at base minute. Trace of 

 rhombic occiput depression. End of muzzle to ear 1" 4'"; ear to vent 4" 3'". 

 Anterior limb 2"; posterior to heel 2" V" ; foot 1" 8'". f 



Yellowish brown, or a series of light small spots on each side of back, bordered 

 with dark brown ; and some vertical series of larger confluent similar spots, dark 

 bordered. 9 with a pale greenish median dorsal band not laterally defined, 

 but bounded between femora and on base of tail by two large brown spots on 

 each side. 



Two specimens, <^ 9 . " W. Indies." 



Anolis all ia c eu s. 



Near leachii, but with larger frontal plates and weaker face ridges, etc. 

 Four rows in the almost flat front cavity smaller than three or four polygonals 

 between terminal scales of front ridge rows ; of these there are three two lying 

 along canthus. Six rows between lateral nostrils. One row between supercilia- 

 ries, which are broader than long, and one row of granules between lateral and 

 supraorbital disc. Some swollen scales round occipital, four (five) loreal rows; 

 between posterior scales of canthus rostralis equal from same to end of muzzle. 

 Ear two-thirds of eye. Symphyseals very large, larger than fir3t infralabial, 

 second larger than inferior labials ; third infralabial large. Lateral scales 

 minute, rough, scarcely smaller than dorsals, except two median rows of 

 larger keeled, which are less than the keeled equal brachials, which are less 

 than weakiy keeled oval abdominals, which are less than keeled prefemorals. 

 A slight fold on nape. Four large inferior caudals. Dilatations not narrow. 

 Fan not very extensile, elongate. End of muzzle to ear 2i times in from ear 

 to groin. Large row of equal caudal crest scales. Laterals small, keeled ; 

 four inferior rows large.
