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, Arthur Schott. 
Types:— U.S. N. M. 6,572 three Corypss, one perfect from which the de- 
scription was evidently drawn: one CotypE M. C. Z. 13,570.4 
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:— Cotyrr 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 eye; 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
