and has only superficial resemblances to the E. flavilabris, 

 Cope, of Mexico. Its peculiar characters are the great width 

 of the lateral color band, which covers three rows of scales, 

 one more than in any other species ; the black borders of the 

 bands ; the absence of well-defined dorsal lateral spots, and 

 the absence of markings on the head and labial scuta. Be- 

 sides these color marks, the presence of a large second tem- 

 poral plate extending to the labials is peculiar to this species 

 if found constant ; and the narrow conical head is character- 

 istic. In the E. ftavilabris the general appearance is some- 

 what similar, but the labial plates are broadly black edged, 

 and the lateral band covers but two rows of scales ; there is a 

 large postoral yellow dark-edged crescent, and the second 

 temporal plate is smaller, and does not reach the labials. 



" It gives me much pleasure to dedicate this handsome 

 species to Mr. Butler, whose interest and labor in the natural 

 sciences have resulted in many interesting discoveries." 



15. Eutccnia radix iiic/aiiokniia, Cope. Black-spottkd 

 Garter Snake. Two specimens were in the Purdue Uni- 

 versity collection (Nos. go and 312). They were sent to Prof. 

 Cope with the others just mentioned, and were considered to 

 be a new form, and described as this species. (Proc. U. S. 

 Nat. Mus., 1888, pp. 400-401). The following is the descrip- 

 tion: " Scales in twenty-one longitudinal rows, the inferior 

 largest and keeled. Superior labials, 7 (8); frontal wide, 

 oculars, 1-3. Parietals long, borders regular. Temporals, 

 1-2, the second above, moderate. Gastrosteges, 153; anal, i ; 

 urosteges, 68. Head distinct ; muzzle short, not protuberant. 

 Lateral stripe on third and fourth rows of scales, not black 

 bordered above or below. Dorsal band on one and two half 

 rows of scales nearly completely black bordered. Between 

 these the dorsal ground color is dark olive-brown, but the 

 space is nearly occupied with the two rows of quadrate black 

 spots. Below the lateral stripe two rows of alternating black 

 spots, one on each row of scales, which sometimes coincide, 

 on an olive-brown ground. Gastrosteges with a black longi- 

 tudinal spot near the end of each, which is frequently con- 

 fluent with the adjacent ones, from two to five running to- 

 gether to form an interrupted lateral central black stripe. 

 Between these, the gastrosteges black edged, except on the 

 anterior fourth of the length. Length, 285 mm.; tail, 65 mm.
