Hence the spur may have been overlooked in specimens which have 

 been long in spirits ; and the distinctness of the spur greatly 

 depends on the presence or absence of this claw. These black 

 claws are to be seen on the youngest specimens as soon as the toes 

 are developed. 



The skin is scattered with small white lines dispersed in a sym- 

 metrical manner, which, when examined by a magnifier of rather 

 high power, display linear series of close minute perforations or 

 glandular openings. Dr. Hallowell seems to have observed some of 

 these ; for he mentions " the semilunar rows of longitudinal glands 

 on the throat ;" but he does not seem to have seen that they are 

 symmetrically distributed over nearly the whole of the body, and 

 especially on the head, the back, and the sides, as well as the throat. 

 He specially observes that the skin is smooth, and that there is no 

 lateral line visible. 



Professor Auguste Dumeril does not take any notice of them in 

 his short observations ; but in his figure of D. Mulleri (t. 18. f. 3) 

 he represents the double series of them that surrounds the back like 

 a double series of short prominences or tubercles, very unlike the 

 sunken line of pores which they are — indeed so unlike that I should 

 not have understood what they were intended to represent on this 

 smooth-skinned Toad, had I not previously observed the glands, and 

 if they were not placed exactly where the double line of pores is 

 situated, and where there are no such prominences on the animal as 

 his figure seems to represent. 



I will now proceed to notice the distribution of the more important 

 of these white glandular lines. There are two horizontal lines, 

 slightly separated in the middle, at the end of the nose, under the 



nostril ; a line between the eye and the nostril; and a series of ob- 

 lique lines across the swollen band which surrounds the eye on the
