Comparing the first group with the recorded characters <>f allied 

 species, it will be found to agree very well with those of A. cveca, 

 which has 227 to 2o<» body rings, 18 caudal rings, 1 temporal, 6 

 preanals, 3 scutes behind the unpaired postmental, and short nasal 

 suture." 



The fact that the types of A. cseca are said to have been collected 

 in Martinique is of no moment whatever, and it is pretty safe to 

 say that the species does not occur 

 there. It is now known that Plee, 

 who sent these specimens to the 

 Paris Museum, collected in Porto 

 Rieo, on his way to Martinique, 

 whence he shipped his material to 

 Paris. 



The three other specimens men- 

 tioned above I can not unite with 

 any other known form, and they 

 will be described further on under 

 a new name. 



Description.— Adult; U.S.N.M., No. 27223; Utuado; April 10, 1900. 

 Rostral small, triangular, the portion visible from above short, about 

 equaling the suture between the nasals; prefrontals very long, the 

 suture between them longfer than the one between the frontals and 

 five times as long- as the nasal suture; ocular moderate, quadrangular, 

 smaller than the postocular and the third supralabial; in the angle 



shields a well-developed temporal, 

 between and behind the latter two 

 only slightly smaller than the ocular; 

 eye plainly visible through ocular; 

 a pair of occipitals, broader than 

 long, in contact behind the frontals; 

 three supralabials, the second as 

 long as the other two together; 

 three lower labials, the second 

 longer than the other two together; 

 mental followed by a large median 

 postmental, twice as long as broad; behind the second lower labial a 

 large malar shield; just behind the postmental and between the malars 

 three scales in a transverse row (postgeneials); 226 rings on the body 

 and 17 on the tail; the segments of each ring longer than broad on the 

 back, broader than long on the under side, 16 above and 18 below the 

 lateral line: anal shields, 6; preanal pores, 4. Color, flesh color, with 



« Characters derived from Durm'ril and Bibron's original description, Strauch's 

 notes upon the types, and Peters's figure of one of the types (Mon. Ber. Berlin 

 Akad. AViss., 1878, plate facing p. 781, fig. 7).
