Cope.] 1^4 [July 16, 



quite elongate, last two each longer than high. Inferior labials nine ; 

 geneials equal, not elongate. Gastrosteges 189, urosteges 70. Total 

 length of a young animal Om 30 ; of tail Om 03.5. 



Color above light brown, with a dorsal series of transverse quadrate 

 deep brown spots extending from nape to middle of tail ; they extend 

 over seven and two half rows of scales, and are restricted by a light yel- 

 low line, which extends on each side the back. The spots are yellow- 

 edged anteriorly and posteriorly. The sides are marked with two rows 

 of alternating pale brown blotches, of which the superior is opposite the 

 dorsal series. There is a triangular dark edged yellow spot on the ex- 

 tremity of each gastrostege ; belly closely brown punctate. A blackish 

 band extends from the rostral plate to the side of the neck, and three 

 similar bands with pale middles extend on the top of the head to the 

 nape. Lips and chin yellow, brown blotched. 



This species was found by Geo. Sceva, of the Thayer Expedition to 

 Brazil, and is No. 909, Mus. Comparative Zoology, Cambridge, Mass. 



Lygophis lachrymans. Cope. 



This species repeats the generic characters of Lygophis in the dia- 

 cranterian dentition, lack of scale pores, tail of medium length and nor- 

 mal scutellation. 



Scales in seventeen series, obtuse. Muzzle short, rostral shield not as 

 high as wide, not prominent. Internasals broader than long ; frontal 

 broad, shorter than occipitals, with a right angle behind. Superior 

 labials eight, fourth and fifth only in orbit, sixth only higher than long. 

 Loreal longer than high ; ocvilars 1-2, the anterior not reaching frontal ; 

 temporals 1-3. Liferior labials large, nine ; pregeneials shorter than 

 postgeneials. Gastrosteges 173 ; anals 1-1 ; urosteges 78. 



Color above, chestnut brown ; ends of gastrosteges and first three and 

 a half rows of scales blackish, yellowish margined above from side of 

 neck to end of tail. On the anterior half the body is divided by a yellow- 

 ish band on the first and second rows of scales. Below and labials bright 

 yellow, the anterior superior labials brown margined. A deep brown 

 band from eye across sixth labial, another across seventh, and a black 

 spot on side of neck. Head above brown. Habitat, unknown. 



This species is remotely like Coniophanes fissidens. It differs from 

 Rhadinaea taeniolata Jan. (Eivicognathus) in the broader frontal, and 

 the lip bands as well as uniform back. 



AliSOPHIS RIJGERSMAEI, Cope. 



Six specimens of this species serve to represent its characters. In 

 three the scales are in 23 series, in one in 21 . The loreal plate is longer 

 than high, and with a straight superior suture, except on one side of one 

 individual, where it is angulated above as in A. antillensis. The muzzle 

 projects considerably beyond the mouth, but the rostral i^late is not pro- 

 longed on its upper surface. Superior labials eight, third, foui'th, and 

 fifth in orbit ; these with the sixth are the only labials liiglier than long. 

 Temporals 1-2 the anterior in contact with inferior of the two postocu- 

 lars only. One preocular occasionally divided and not reaching frontal.
