The t loacal iv^ioii is r(»iisi(li-riilily swollen, and is liioad and loiiiidfd, 

 oisli'^lill.v fniar^iiialr lu'liind. i'lic distaiict' lioui the {,'ioiii IoIIu'ikks. 

 U'lior cud of the vent in tliis species is jircater pntportionall.v (liaii in 

 any other of the j^cnus so far as I liave I»cen aide to dctcrniiMc. It JM 

 contained in tlie distance from tlie snoni to the ;;n»iii Init .'{,', limes. 



Tile tail is e(|nal in !en;^tli to llic distance from tlie snout to tlio be- 

 ^iuniu;^ of the vent. It is niucli compressed and rather liinli. ItluiHU 

 well ileveloped keel or crest, which l)e;jfins luinitMlialeiy over the chmc-ii 

 and extends to the tii» of the tail. The keel is sharp above, and is 

 bounded below on each side liy a shallow <;ro(»ve. inferiorly the tail 

 is broadly rounded for its anterior third or nn)re, and is traversed by a 

 median longitudinal {rroove. The remaimler (»f its lower Ixuder is 

 compressetl t(» a sharp ed^^'. A tiansveise section of the tail, taken Just 

 behind the cloaca, would form approximately an isosceles triangle whose 

 base would be about one half ils heij^hf. One-third of the distance back 

 toward the tip the heijjfhtof the tail is three times its thickness. 



The limbs aic well developed. The posterior aic a little loiij,'er, some- 

 what stouter, and the foot broader than the sanu^ limbs of a specimen 

 of A, tiiiriuinii that measures the same distance from the snout to the 

 end of the vent. They are also tally as lon^j as the same lindis of ji 

 specimen of A. punctdtinn that measures from snout to the end of the 

 vent tliieefourths of an inch moic than the specimen 1 am describin<;. 

 The t(»esare Hat, much like those of .1. titjtinniii. perhaps not so broad, 

 while they are not so slender as those of a specimen of .1. itiunlnliiin 

 now betbre nie. They are jjidvidcd with a narrow niar;4inal and basal 

 membrane. There are two distinct i>lanlar tubercles.
