arranged in regular transverse series and with a median series of wide 

 I)lates below, the space between them and the lateral edge being occu- 

 pied by several series of imbricate rounded scales near the base, form- 

 ing as many as five rows. No femoral pores (female). 



Color above nearly uniform drab with faint indications of darker 

 brownish markings on the head, as well as of a white transocular stripe 

 bordered above and below with dusky; underside whitish, but dusted 

 over with minute specks of blackish; these minute specks are also 

 present all over the upper surface, oidy much denser. 



Dimensions. — Total length, 95 mm. ; snout to vent, 46 mm. ; vent to tip 

 of tail, 49 mm.; snout to ear-ojiening, 12 mm.; greatest width of head, 

 9 mm. ; fore limb, 12 mm. ; hind limb, 16 mm. ; from axilla to groin, 21 mm. 



Yariation. — A not uncommon deviation from the above description 

 consists in the presence of a small granule at the juncture of the ros- 

 tral cleft with tlie sutures of the supernasals, to which is sometimes 

 added one or more granules in the suture between these two shields, 

 which may then become entirely separated, as in one of Knudsen'.s 

 si>eciniens from Kauai (No. 23482, U.S.N.]\[.). The size of the exterior 

 pair of chin-shields is also somewhat variable, the extreme being No. 

 23481, U.S.N.M., in which it has entirely been broken up into small 

 scales like those adjoining the infralabials. 



The regenerated tail resembles the original one very much and lias 

 well-developed snbcaudal plates, but it seems to be broader at the base, 

 and shorter, while the scales are more irregular and more pointed. 



The color markings vary also to some extent, being more pronounced 

 and definite in some examples than in others. Thus in No. 23501, 

 U.S.N.M., there are three distinct series of brownish spots, one median 

 and two lateral, with pale markings between, the median series extend- 

 ing to the neck and occiput where it forms a distinct line. In this 

 specimen the white, dusky-edged line from nostril through eye to above 

 ear is very strongly marked. 



An immature male (No. 902, Oberlin College collection) has about 

 seventeen obscure femoral pores on each side meeting at an angle, 

 directed forward, on the preanal region, the scales behind the angle 

 being larger and more dift'erentiated than in the female.
