bcEus Cope, and in some respects differs from both. Wliether there is one 

 variable species or not, more abundant material is necessary to decide. 



CxENOSArRA, sp. joung, Nos. 376, 377. 

 Iguana tuberculata, L., No. 378. 



Anolis longipes, sp. nov. 



Size of A. biporcatus ; head short, wide ; limbs long, the posterior when 

 extended reaching the end of the nose. Tail cylindric, covered with scales 

 of equal size, which are freely keeled above and below. Tibia equal 

 length of head to auricular meatus, and longer than length to occiput. 

 Scales of body of medium size, subequal, those of belly imbricate and 

 keeled ; those of back not imbricate and smooth. Occipital plate rather 

 smaller than the large auricular meatus, and separated by two rows of 

 scales from supraorbital rows. The latter are separated from each other 

 by two rows of scales. Frontal ridges well defined, and separated from 

 each other by five and six rows. Five loreal rows and six supraorbital 

 rows, the latter diminishing in size gradually outwards. Scales of limbs 

 k-eeled. Scales of top of head, including supraorbitals, with a single keel. 

 Tail elongate. 



Color brown above, dirty white below. A dark -brown band originates 

 on each side of the occiput, and extends continuously on the basal part of 

 the tail. On the body a delicate brown line extends above and parallel to 

 it. A dark-brown cross band between orbits, and a dark-brown chevron 

 with the angle pointing backwards on the prefrontal concavity. Four 

 broad dark cross-bands across lips ; limbs indistinctly cross-banded.

Length of fore foot 17

Palmar, No. 343, adult ; No. 299, Boruca, young. 



The small size of the fan in No. 343 indicates that it is a female ; it is 

 much better developed in the young. No. 299, which is quite small. In 

 the young, the scales of the head are not keeled, and the keels of the ad- 

 dominal scales are less distinct. The color is a bright yellow, with a broad 

 brown band surrounding the head above and below at the orbit, and 

 another capping the nose and chin, the loreal region remaining yel- 

 low. The yellow cross-band on the chin which separates these two areas 

 leaves a visible trace on the adult.
