Descriptions of new species of the Reptilian genera Hyperoliur, Liuperus and 



Tropidodipsas. 



BY E. D. COPE. 



HYPEROLIUS FULVOVITTATUS Cope. 



Tympanum concealed. Head elongate, external nares lateral. Internal 

 nares circular; eustachian orifices elongate oval. Tongue elongate, deeply 

 bifid. Skin of the dorsal region smooth. Tibia longer than femur ; fifth toe 

 much shorter than the fourth, and longer than the third. Length of head 

 and body 10 h lines. 



Coloration. Above pale yellowish brown (in spirits), with a light fulvous 

 band upon each side, passing from the end of the muzzle to the thigh. 

 Two bands of the same color extend one on each side of the vertebral line, 

 and passing above the eyes, become confluent on the muzzle. These bands 

 are about as wide as the spaces of ground color they enclose. Beneath, light 

 yellowish brown.

Liuperus biligonigerus Cope. 



Form very stout. Head broad, short, frontal region a little wider than 

 each palpebra. Muzzle prominent, very obtuse in profile. Canthus rostralis 

 rounded, nostrils vertico-lateral. Eyes very prominent. Tympanum con- 

 cealed ; eustachian orifices exceedingly minute. Tongue small, elliptic ob- 

 long, entire. Skin above and below very smooth, some granulations upon 

 the posterior faces of the femora. A few small glandulous elevations between 

 and posterior to the eyes, and upon the anterior part of the back. A pectoral 

 fold. Two rounded tuberosities on the carpus ; fourth digit shortest, third 

 longest. Femora very stout. Tarsus equal to the fore arm in length, fur- 

 nished with a minute, acute tubercle near the middle of its posterior face, 

 which is not brown tipped ; and at its inferior extremity with two transverse, 

 compressed tubercles or spurs, which are tipped with brown. Metatarsus not 

 tuberculous. Length of head and body measured beneath, 11 lines ; of tibia, 

 4^ lines. Breadth beneath, from axilla to axilla, 4 lines. 



Coloration. Above marbled with pale rufous brown, with darker markings 

 intermixed. These are, a narrow band bisecting each eyelid ; a blotch extend- 

 ing from eye to shoulder ; a pair of small spots upon the back, posterior to 

 the eyes ; another larger pair, one behind each suprascapular region ; one 

 upon each side of the coccyx ; a curved band extending from iliac region to 

 femur, and a lateral band extending from behind the shoulder, which 

 vanishes before reaching the thigh. A pale dorsal line, lightest posteriorly. 

 Beneath, dirty white. 



Hab. Buenos Ayres. Mus. Acad. Nat. Sci. Presented by Dr. Kennedy. 



In Liuperus marmoratus D. Sf B., the tympanum is distinct, and the 

 skin is very tuberculous. In L. sagittifer Schnu, the frontal region is 

 much narrower, and a series of tubercles extends from the eye, posteriorly. 



Tropidodipsas lunulata Cope. 



Body much compressed, its vertical diameter near the middle two and a 

 half times as great as near the neck. Tail slender, cylindrical, between one- 

 fourth and one-third the total length. Head very distinct, elongate, de- 



Note. The following papers, viz., "Mexican Humming Birds, Nos. 3 and 

 4," by Raphael Montes de Oca, " Contributions to the Carboniferous Flora of 

 the United States, No. 2," by Horatio C. Wood, Jr., and "Contributions to 

 American Lepidopterology, No. 7," by Brackenridge Clemens, M. D., were 

 read to the Academy Nov. 20th, but were inadvertently omitted in the minutes 

 of that date.
