medially, and iioarly or (luite in contact. Tho i)t<,Mygoi(l patcbes com- 

 mence at some distance behind these. They are of usual breadth, but 

 diver^ife more posteriorly than in the species of the lirst section of the 

 jrenus, resembling thus many species of Spelerpes. Tlie teeth are very 

 minute, and are arranged in series directed backwards and inwards. 

 The tongne is a little more free than in P. ffbitinnsus, as the lamina 

 connecting the anterior and nie<lian points of support is «piite thin. 



The inner toe in both i)air of limbs is (juite snuill, but free and better 

 developed than in P. f/lutlnofim. In the anterior i)air the third is the 

 longest; the second is a little shorter than the latter, aiul the fourth a 

 little longer than the lirst or inner one. The longest toe in the poste- 

 rior limbs is the third likewise, the fourth being nearly equal to it, 

 whilst the second is a little longer than the fourth, which itself is a 

 little more develoju'd than the lirst or innermost. Phalanges 1-2-3-2; 

 l_2_;{-3-2. 



The skin is perfectly smooth externally, but on being examined under 

 the microscope it exhibits a nuvsh-work of little stellated mucous pores, 

 similar to those of Auto(1a,v liignbi-is, but proi)ortion!illy larger. 



According to a sketcth from life made by Mr. Drayton, of the United 

 States l"^\pl()ring I"]xpedition, the ground color is milky white, with 

 crowded dots of reddish brown. On the si)ecimens preserved in alcohol, 

 however, the b()dy, head, and limbs are of a unifornj dark brown, lighter 

 beneath. Under a low magnifying power minute dots may be observed 

 vsciittered all over the surface. The <rolor would appear to vary sonte- 

 what. A drawing in the Smithsonian re<!ords, <'()Iored fnun life by 

 Samnels, represents the sides of head and body with lower snrface of 

 t.iil and anterior faces of limbs of a bright orange. This is the color of 

 living specimens which I have tak» i myself.
