have a small intercalated scale between the second and third. No. 1193, 

 from the Saint Mary's Eiver, August, is larger than the other, measur- 

 ing about thirty-six inches 5 it is similar in general coloration, but less 

 richly marked, the red suffusion being of less extent and intensity. 



This slender and elegant species was only observed at and near the 

 end of the Line, at the eastern base of the Eocky Mountains, in August. 

 It was common in the clear cold waters of the lakes and streams, and 

 appeared to be one of the most thoroughly aquatic species of the genus, 

 being often seen swimming freely in deep water at some distance from 

 the shore. At this season, all the female individuals observed were gravid 

 with nearly matured embryos. Like other of the genus, the species is 

 ovo- viviparous, the young being some six inches iu length when born. 

 Newly-born individuals are of an indefinite dark color, with pale bands 

 and under parts, without red, but with two rows on each side of very 

 evident blackish specks — markings like those that persist in the adults 

 of U. vagrans, for example. In two young specimens found in utero, 

 the genital or intromittent organs are external to the anus, and 

 extremely large when compared with the size of the individual. The 

 placental cord is attached a short distance in advance of the anus.

Description (No. 1027, Pembina, June 5, 1873). — This is one of the 

 stoutest species of the genus. A specimen two feet long equals or rather 

 exceeds in calibre a three feet long individual of sirtalis for example. 

 The rapidly tapering tail, in a specimen 30 inches long, is 6^ inches, 

 or contained about 4| times in the total length — nearly 4 times in the 

 length of body alone. The head is very short and thick, with a broad 

 obtuse muzzle. The dorsal stripe, one scale and two half-scales broad 

 throughout, is firm and continuous along the body, but less evident 

 (sometimes extinguished altogether) on the tail. The lateral stripe is 

 fairly two scales wide along most of the body, but only a scale and a 

 half posteriorly, and but one scale on most of the tail; on the body it 

 occupies the third and, for the most part, the fourth row of dorsal scales ; 

 on the tail it descends at once to the first row. Both dorsals and lat- 

 eral bands are alike clear pale yellow, the former only occasionally deep- 

 ening anteriorly into a more golden- or chrome-yellow. The body is oli- 

 vaceous-blackish or obscure brownish-black, and of much the same tint 

 above and below the lateral stripes. In the darkest and most "pitchy" 

 black individuals, no markings are evident ; in some lighter ones, there
