supranasals broadly in contact, larger than prefrontals; frontonasal 

 longer than wide, behind broadly in contact with frontal; anterior 

 loreal formuig a suture with frontonasal; four supraoculars, the three 

 anterior in contact with frontal; six superciliaries ; one pair of 

 nuchals in contact with posterior border of ]:>arietals and interparietal ; 

 seven supralabials, fifth bordering the orbit, seventh largest; one 

 unpaired postmental ; ear-opening slightly larger than largest dorsal 

 scales and bordered anteriorly by about 5 distinct obtuse tubercles; 

 30 scale rows round the middle of the body, the laterals very much 

 smaller than either ventrals or dorsals, the two 

 median rows of the latter slightly larger than 

 the others ; two very large preanal scales ; length 

 of hind limb (from groin to tip of fourth toe) 

 contained twice in the distance from snout to 

 vent; limbs overlap consideral>ly when pressed 

 against the body; no continuous row of tuber- fig. isi.— eumeces lati-

median series or subcaudals transversely enlarged no. 23895, u.s.n.m. 

 anteriorly. Color (in alcohol) above uniform dark 



olive; an obscure brownish band proceeds from eye backward above 

 the limbs disappearing at the base of tail; this band is bordered above 

 by an ecpally obscure pale band, these bands so obscure as to be 

 imperceptible in the specimen when taken out of the alcohol ; under- 

 side bluisli, chin and throat whitish.

Remarks. — The present species is most nearly related to E. lati- 

 scutatus from the main island opposite, and is probably a direct off- 

 spring of the latter. It differs chiefly in the greater number of scale 

 rows round the middle of the body and apparently also in a some- 

 what different coloration, inasmuch as even young specimens of 

 the island form are of a more or less uniform olive color without the 

 strongly marked pale lines so characteristic of the main island speci- 

 mens of corresponding size. They are only plainly marked in the 

 smallest specimen from Niishima, measuring 40 mm. from snout to 

 vent, and even in this specimen the median line does not reach the 

 head. 



The additional number of scale rows makes the diagnosis of the 

 new species read even more like that of E. fasciatus of the United
