Mesofeltis multipasciatus. Leptognathus rmdtifasdatus Jan. MS. 

 Bocourt, Bullet. Soc. Philomathique, Paris, March, 1884. Asiheno- 

 gnathus Bocourt. 



The genus Asthenognathus Boc, 1884, appears to be identical with 

 Mesopetis Cope, 1866. 



Edt^nia insigniarum, sp. nov. 



Scales in twenty-one rows, all keeled except inferior row, which some- 

 times presents short keels at the bases of the scales. Superior labials eight, 

 eye over fourth and fifth. Three postoculars. Temporals 1-3. Lateral 

 band on the third and fourth rows of scales. No dorsal band, but the 

 dorsal region yellower than the sides for a width of from four to six scales. 

 A row of black spots above the lateral stripe, which are sometimes divided 

 so as to form two rows one above the other. A row of incomplete black 

 spots below the lateral line, which are formed by the adjacent black edges 

 of three or four scales. A black spot on each side behind the angle of 

 the mouth, which extend upwards to near the occipital shields, and is 

 preceded by a light spot of half crescentic form. The last superior labial 

 and temporals in front of this space, have black edges. Superior labials 

 slightly black-edged. No spots on the parietal plates. Gastrosteges, 164 ; 

 urosteges, 68 to 74. Total length of a rather small specimen, M. .435 ; of 

 tail, .096 ; to canthus oris, .014. " 



I took the typical specimen of this species from a bunch of herbage 

 which grew from the wall of the aqueduct at the castle of Chapultepec 

 near the city of Mexico. Professor Herrera, director of the Escuela Pre- 

 paratoria of the city of Mexico, showed me a living specimen which was 

 taken near the city, and gave me a third, preserved in spirits. M. Bocourt 

 sent a specimen to the Smithsonian Institution, and Dr. Duges gave me 

 a fifth, which was taken near Guanajuato. 



This species is nearest to the E. flavilahris. I give comparative diag- 

 noses of these two, together with that of a third species which is related to 

 both, which I obtained on the upper waters of the Gila river in New 

 Mexico.
