NATURAL SCIENCES OP PHILADELPHIA. 173 



disc. Six superior labials ; five loreal rows. Disc composed of two rows of 

 broad scales ; the inner larger, keeled. Infralabials longitudinal, smaller 

 than labials. Fan large. Ear one-third of eye fissure. Nostrils opening late- 

 rally. Femur and tibia of moderate length. Tail very long; its scales 

 larger than dorsal or ventral. Knee and elbows not meeting on the side by 

 the length of the humerus ; heel not reaching axilla, longest toe posterior 

 part of orbit. Digital dilatations narrow. Muzzle to ear enters three and one- 

 half times into from muzzle to between femora. Pale yellow, with faint cop- 

 pery and green reflections. Head tinged with brown ; labial plates whitish.

Auolis nannodes. 



Very slight concavity on muzzle; ridges low; scales of front broad as long, 

 smooth or slightly roughened. Superciliaries in contact ; small flat scales 

 round the occipital. Dorsal scales very much smaller than those of front, and 

 equal abdominal ; seven or nine rows in the middle a little larger. Infralabials 

 numerous, little distinct, equal, keeled. Loreals four or five rows ; canthus 

 rostralis nearly straight from angle of eye ; eight rows between canthal rows 

 at middle muzzle. Ear \ size of eye opening. Eye not prominent. Two rows 

 supraorbitals ; inner much larger ; four or five transverse in curved series se- 

 parated by granular scales from superciliaries. Tail and extremities short; 

 digital dilatations broad. End of muzzle to tympanum V* 2 /// ; former to vent 

 4" 5'"; hind foot 1" 1>"; limb 2" 5'"; tail 7". 



Light reddish brown, with a brown cross band between eyes and across 

 muzzle, and spot on each side of sacral region. The male with indistinct 

 brown cross lines on back ; female a darker median shade, and indistinct 

 blackish line on each side. 



Three specimens, two from Godman and Salvin's collection from Coban, 

 Vera Paz, Mus. Brit. Sp. 6116 Mus. Smiths., Arriba, Costa Rica, from C. N. 

 Riotte, and No. 61 17 Xalapa, De Oca. 



Anolis c r a s s u 1 u s. 



Differs from sallei in larger ventral and dorsal scales ; in smoother, 

 broader scales of front, especially superciliaries and supraorbitals. More 

 numerous supraorbitals ; shorter muzzle, a few larger, smoother infralabials. 

 Differs from nebulosus in number and separation of superciliaries and in 

 supraorbitals, apparently. 



Eyes rather small ; muzzle not long, not short, rounded acuminate, a little 

 depressed at tip. Frontal depression strong, containing five or six scales, count- 

 ing across its anterior part. Superciliaries as broad as long, separated by one 

 or two rows (in one specimen in contact, perhaps abnormally) ; eight from 

 canthus rostralis to point nearest occipital ; all scales of front smooth, thick, 

 as broad as long. Two rows broad subhexagonal supraorbitals, four or five 

 broader on inner row, forming a disc not surrounded by granules. Two or three 

 outer infralabials equal inferior labials. Goitre well developed. Four loreal 

 rows : 13 14 rows of dorsals graduating rather suddenly into laterals ; a little 

 smaller than ventrals and prefemorals. Tail stout at base. Ear \ J eye slit. 

 Pale reddish brown, below yellower ; top of head darker ; front loreal region 

 through eye along each side of neck a brown indistinct band, bounded below 

 by a narrow yellowish one from whole labial length, which is prolonged 

 posteriorly. 9 with a yellow dorsal band. End of muzzle to ear 1 // 4 /// , to 

 vent 4" 7"'; hind foot \" 7"'; heel to groin 2" ; tail 9".

Anolis c y m b o p s. 



Width of head between temporal ridges equal to its perpendicular diameter 

 at occipital plate ; muzzle rather short, acuminate ; loreal region straight,
