1H82.] M. BOULENGER ON A NEW SPECIES OF SCELOPORUS. 761 



series of confluent sagittate black spots, the points acute, directed 

 outwards between each pair of nervules ; the margin narrowly black. 

 Expanse 1*7 to 2*0 inches. 



A. helucha is intermediate between A. soracta and A. nobellica ; 

 it diflers from A. soracta in the far greater prominence of its black 

 markings, and from A. nobellica in having the base of both wings on 

 upperside white and black, and from both by its smaller size. 



Habitat. Beluchistan. The type specimens were taken by Col. A. 

 M. Lang, R.E., on the Ziarut Pass, near the Kawas valley, at an 

 elevation of 8000 feet above the sea, on the 18th June, and are now 

 in my collection. 



For the greater part of the material for this paper I am indebted 

 to Col. A. M, Lang, R.E., who has very kindly placed the whole of 

 his collections and papers at my disposal for use in the ' Handbook 

 of the Butterflies of India, Burmah, and Ceylon,' which I am now 

 bringing out in conjunction with Mr. Lionel de Niceville, of the 

 Indian Museum, Calcutta. 



9. Description of au apparently new Species of Lizard of 

 the Genus Sceloporus. By Gr. A. Boulenger^ C.M.Z.S. 



[Eeceived December 5, 1882.] 

 (Plate LVI.) 



The Society, as just reported by our Secretary (above, p. 719), 

 has received from Dr. S. Garman of Cambridge, U. S. A.., five living 

 specimens (4 females and 1 male) of a species of Sceloporus from 

 Dacota, which appears not to have been described. They were sent as 

 Sceloporus undulatus, var. That this Lizard is totally diiferent from 

 Bosc's species will be shown hereafter. 



After researches among the descriptions of American authors, I 

 came at first to the conclusion that they might be Sc. phayeri, 

 Baird ; but on entering more closely into the question, I had to 

 abandon this view, and I am now satisfied that they belong to an 

 undescribed species, allied to Sc. gracilis, Bd. & Gir., for which I 

 propose the name Sc. garmani, in honour of Dr. S. Garman, of the 

 Museum of Comparative Anatomy, Cambridge. 



Sceloporus garmani, sp. u. (Plate LVI.) 



Small species with smooth head-shields and moderate-sized dorsal 

 scales. Length of the head contained four times or somewhat more 

 in the distance from end of snout to vent. Head-shields normal, 

 smooth ; a row of four or five transversely dilated supraorbital 

 shields ; canthal shields two ; anterior border of ear-opening with a 

 strong denticulation formed of three or four large pointed scales • 

 six or seven upper, and eight or nine lower labials. Dorsal scales 

 quadrilateral ; sharply pointed, strongly denticulated or rather tri-
