spot near the gastrosteges. Belly speckled with dark brown; a 

 median stripe of speckles. Labials unspotted. Top of head 

 brown, with a pale Y on parietals, a cross on frontal, and trans- 

 verse pale borders to the frontal, prefrontal and internasals. 

 One specimen, No. 44a. 



Himantodes cenchoa Linn. Six specimens, of which all 

 but one have a single preoeular plate. In the other the superior 

 part of this plate is separated from the remainder by a suture. In 

 all there are two temporals of the first row. In both these char- 

 acters these specimens differ from my specimens from Ecuador 

 and Peru east of the Andes, and agree with the II. sernifasciatus 

 of Central America. They have the broad vertebral scuta of the 

 true II. cenchoa. I incline to leave the Columbian specimens 

 with the H. cenchoa, and to regard their characters as requiring 

 that the II. semifasciatus be regarded as a subspecies of the 

 same. 



Oxybelis argenteus Daud. One specimen, No. 31. 

 Oxybelis acuminatus Wied. One specimen, No. 30. 



PROTEROGLYPHA. 



Elaps mipartitus D. & B. Fifteen specimens, Nos. 36, 51, 

 52, 53 and 55. The anterior temporal is not especially narrow in 

 any of the specimens, and the gastrosteges reach as high a num- 

 ber as 305; urosteges 25. The light annuli vary from 51 to 71. 



Elaps fulvius Linn. Five specimens, Nos. 11, 24, 33, 35 

 and 37. A variety in which the black of the head extends to the 

 extremity of the parietal plates, and there are from sixteen to 

 twenty-five black annuli on the body. These are not yellow- 

 edged, and are separated by red interspaces much wider than 

 themselves, in which all the scales are black-tipped. This group 

 includes the var. H. of Boulenger, whose only specimen is stated 

 to come from Yucatan, and to have nineteen black rings. 



SOLENOGLYPHA. 



Lachesis lanceolatus Lacep. Eighteen specimens. Nos. 32, 

 42, 61, 63, 64, 65 and 66.
