DESCRIPTION OF A NEW EUBLEPHARID LIZARD^ 



FROM COSTA RICA. 



BY G. K. NOBLE. 



In a collection of reptiles and amphibians from Costa Rica 

 recently presented to the Museum of Comparative Zoology by 

 Mr. H. S. Blair of the United Fruit Company there is an unde- 

 scribed species of the genus Lathrogecko. It may well be called : 



Lathrogecko xanthostigma sp. nov. 



Diagnosis. — Head slightly more than one and one-half times as long as 

 broad ; snout as long as the distance from the ear to the orbit ; dorsal 

 scales very small, rounded, slightly tubercular; nasals followed by a 

 group of three small post-nasals; mental moderate in size, followed by 

 several small scales; five upper labials, four lower labials; ventral scales 

 very much larger than the dorsals. 



Type. — M. C. Z., 11,658; Zent, near Puerto Limon, Costa Rica; H. S. 

 Blair collector and donor. 



Habitat. — Only known from the type locality. 



Description of the type specimen. — (Adult. ) Snout moderately pointed, 

 the distance from the orbit to the tip of the snout exactly the same as the 

 distance from the ear opening to the orbit; ear opening moderate, ellip- 

 tical and horizontal. Rostral large, cleft above, a distinct ridge around 

 the upper edge; rostral bounding the nostril anteriorly. Four or five 

 upper labials; four lower labials; both series grading off gradually in 

 size posteriorly. Mental only moderately large, cut by two small grooves 

 posteriorly and followed by a cluster of scales much larger than the 

 granules of the throat ; gulars similar to the dorsal granules but smaller. 

 Body depressed; dorsal surface covered with small, rounded, slightly 

 tubercular scales, those on the snout being larger than those on the 

 occipital region but smaller than those on the upper surface of the body ; 

 ventral scales large, rounded, smooth and imbricate; lower surfaces of 

 legs and arms with similar scales spreading anteriorly over part of their 

 upper surfaces.
