/?. Two rows small spots on each side, those of the dorsal rows separate; 

 no large blotches on the belly. Three sp. from New Providence ; Bahamas. 



y. Gray without spots or with traces only. Three sp. from New Provi-

Ungalia semicincta. Ung. mactilaia, var. semicincta Oundlach and Peters, 



Monatsberichte Preuss. Acad. 1864, 388. 



This is a handsome and distinct species, described as a variety as above, 

 most probably, though the authors have not noted its essential peculiarities 

 of proportions of body and the number of scuta. 



Three specimens (2 Smithsonian, 574G) from Eastern Cuba. Chas. Wright. 



Ungalia oiPSAOiNACope, sp. nov. 



This is a long slender species, much compressed, with slender neck, 

 and small flat and broad head ; its form is thus more like that of Dipsas than 

 any other of the genus. The anterior upper labials are larger than 

 in the other species, the second reaching to the preocular on one 

 side, and within a hair's breadth on the other. Ten labials on one side, nine 

 on the other, two only in orbit. Oculars 1 — 3; temporals 3 — 3 — 4; inter- 

 nasals and prefontals of equal length ; occipitals short, separated by two 

 scales. Eight dorsals, and the basal series of scales larger than the lateral 

 scales, some of the latter slightly roof-shaped. Two pairs of longer genials. 

 The eye is larger than in the other species, its diameter entering the length 

 of the muzzle 1-5 times. The width of the head behind nearly equal its 

 length from the end of the muzzle to near the end of the occipitals. The 

 diameter of the body an inch behind the head, one half that of the thickest 

 part of the body. Urosteges 42. 



Color above a deep reddish brown, with a row of black spots on each side 

 the median line about two scales wide, and always distinct, and two alterna- 

 ting rows of smaller black spots on each side. A series of blackish cross- 

 bars on the belly, two and three scuta apart, sometimes divided and alterna- 

 ting, invade the first row of scales ; no spots for two inches behind the chin. 

 Head dark above, with a darker spot on the occipital region. Ground color 

 below, yellowish brown. 



Total length 15-5 in. ; of tail 2 in. ; of gape 6 lin. 



Habitat. — Cuba, section unknown. Discovered by my friend Prof. Poey, 

 of Havana, who sent a specimen to the Museum of the Academy of Natural 

 Sciences.
