240 SPHAERODACTYLUS. 



glaucus is more northern in its range. Both species are known, however, from 

 Guatemala. Peters's type of inornatus, apparently a synonym of this species, 

 is said to have come from Mexico, far from the known range of lineolatus. It is 

 more probable that the locality is incorrect than that Peters so noted for his 

 precise and careful observing would have missed the peculiar dorsal squamation 

 of glaucus.

Type-locality: — Near Merida, Yucatan, .\rthur Schott. 



Types: — U. S. N. M. 6,572 three Cotypes, one perfect from which the de- 

 scription was evidently dra^Ti: one Cotype M. C. Z. 13,570.* 



Distribution: — Apparently characteristic of Mexico and Upper Central 

 America, as lineolatus is of Lower Central America. A conspicuous exception 

 being the fact that the type of Peter's inornatus which seems referable to lineo- 

 latus as a synonym was said to have come from Mexico, possibly through some 

 metathesis of data. 



Diagnosis: — Rather small, slender, narrow headed, with small, smooth, 

 imbricate dorsals and with no granular middorsal zone. 



Description:— CoTYFE M. C. Z. 13,570 (U. S. N. M. 6,572, part). Snout 

 rather short not conspicuously depressed nor acute; eye slightly nearer tip of 

 snout than ear-opening; rostral rather small with a median groove; nostril 

 between rostral, a rather small supranasal and two small scales one occluding the 

 nostril from the first supralabial; the supranasal of each side separated from its 

 fellow of the opposite side by a single small scale; the suture between the third 

 (large) and fourth (a very small) supralabial under the centre of the ej'e; super- 

 ciliary spine present; head above and on sides covered with small, roundish 

 granular or very slightly imbricating almost smooth scales those on snout some- 

 what enlarged; scales of back slightly enlarged, smooth, imbricate about fourteen
