Two specimens were obtained at Omilteme, Guerrero? 

 Southern Mexico, by Dv. U. Gadovv a few years ago, and I 

 referred them to G. liocephalus. A number of specimens, 

 from the same locality, contained in a collection made by 

 Mr. H. H. Smith, and recently presented to the British 

 Museum by Mr. F. D. Godtnan, show the necessity of 

 proposing for them a new specific name. G. liocephalus 

 differs in the more elongate body, with more numerous trans- 

 verse series of scales, in the longer head, and in the coloration. 



Lygosoma kitsoni. 



Section Riopa. Body elongate, limbs moderate ; the 

 distance between the end of the snout and the fore limb is 

 contained about once and a half in the distance between 

 axilla and groin. Snout short, rounded. Lower eyelid 

 scaly. Supranasals present, small ; rostral broadly in contact 

 with the frontonasal, which forms a narrow suture with the 

 frontal ; latter as long as or a little longer than the fronto- 

 parietals, in contact with the first and second supraoculars ; 

 four supraoculars ; eight supraciliaries, first largest ; fronto- 

 parietals distinct, larger than the interparietal ; parietals in 

 contact behind the interparietal, followed by a pair of 

 nuchals ; fifth upper labial largest and below the eye. Ear- 

 opening small, oval, with two or three small projecting 

 lobules in front. 30 smooth scales round the body, subequal 

 in size. Piseanals not enlarged. The adpressed limbs fail 

 to meet. Digits short ; fourth toe a little longer than third 

 with 11 lamellae interiorly. Tail tapering from the base, not 

 more than once and a half as long as head and body. Brown 

 above, with some small blackish spots on the vertebral 

 region and a dark brown lateral band edged above with 

 lighter; lower parts white.
