A collection of reptiles recently secured for study from the 

 Museum of Comparative Zoology contains a specimen of an 

 apparently undescribed species of Anolis from Santarem, Brazil. 

 I wish to dedicate this species to Charles Linden, in recognition 

 of his excellent work as a collector in tropical America, where 

 he was assistant to Prof. Louis Agassiz during his several years' 

 exploring in Brazil on the famous Thayer Expedition. 



Anolis lindeni sp. now 



Diagnosis. — Size rather large. Tail rather strongly compressed to the 

 distal third, with a trenchant dorsal ridge provided with a dorsal series 

 of enlarged scales. Length of tibia equal to distance from end of snout 

 to hall way between eye and ear. Dorsal scales keeled, very small, be- 

 coming slightly larger <>n the median line, and grading into the minute 

 laterals. Ventral scales smooth, much larger than the dorsals. Upper 

 head scales smooth. Occipital scale large, as large as ear opening and 

 larger than adjacent scales, separated from the supraorbital semicircles 

 by a row of large scales. Scales of the supraorbital semicircles large and 

 in contact medially. Digital expansions broad. A few slightly enlarged 

 postanal scales and a moderately well developed gular pouch in the 

 male. Color above, pale yellowish indistinctly marked with brown; a 

 rather poorly defined stripe from eye to above ear. 



Habitat. — Vicinity of Santarem, Brazil. 



Type specimen. — Oat. No. 8306, Museum of Comparative Zoology; San- 

 tarem, Brazil; Charles Linden, collector. 



Description of type, specimen. — Male. Size large, total length, 145 mm.; 

 tail length, 85mm.; hind limb, -IS mm. The adpressed hind limb reaches
