are disposed upon a transverse and rectilinear series, immediately in 

 advance of the anterior margin of the latter openings, and widely in- 

 terrupted in the middle. The inner nostrils, themselves, are subcir- 

 cular, proportionally smaller than in the preceding species. The 

 openings of the Eustachian tubes are smaller than the latter, but 

 quite distinct. 



The body is elongated, raniform, broader than deep, narrowest pos- 

 teriorly, and continuous anteriorly 'with the head. 



The limbs are slender, intermediate in length between those of E. 

 nasuta and E. hufonium. The dilatations of the toes and fingers are 

 proportionally small, and in that respect more like E. hufonium, 

 although the shape of the body be so widely different. The anterior 

 legs, when stretched alongside the body, reach the posterior extremity 

 of the trunk with the tip of their fingers. The posterior ones, when 

 brought forwards in a similar manner, extend beyond the snout, of 

 the whole length of the foot and half the metatarsus. The first fin- 

 ger is shorter than the second, both of which are provided with a sub- 

 articulary tubercle, whilst there are two of them to the third and 

 fourth. The palm of the hand is inconspicuously tuberculous ; a 

 rather large, subspherical, or subconical tubercle may be seen upon its 

 base. The base of the first finger is provided with a more elongated 

 and smaller tubercle. The toes are slightly webbed at their base, 

 and bordered with a membranous fold. The first toe, the shortest, 

 has but one tubercle underneath ; the others have each two. The 

 sole of the feet is perfectly smooth ; as to the metatarsal tubercles, 

 the outermost is small and subconical, whilst the other is elongated, 

 slightly raised, and resembles a rudimentary finger. 



The skin is perfectly smooth throughout. 



The ground color above, is fuliginous or yellowish-brown ; the head 

 and back provided with very obsolete spots, appearing almost unicolor, 

 except on the posterior third of the body, where small blackish-brown 

 spots are distinctly observed. Along the upper margin of the snout 

 and over the rostral distance to the eye, there is a deep chestnut-brown 

 or, mayhap, black vitta, which crosses the eye, passes above the tym- 

 panum, and extends along the back, to disappear entirel}^ amidst the 

 spots on the posterior third of the body. The tympanum itself is 

 surrounded, and probably covered, by a deep-brown spot. A whitish 

 narrow band extends from beneath the eye to the shoulder, in passing 

 under the tympanum, where the band may be interrupted, leaving an
