CKOCODILIANS, LIZARDS, AND SNAKES. 1(>71 



Scales in iiiiu'teeii rows; superior labials, seven. Lower rows of 

 scales wide, smooth. The head is not very distinct from the neck. 

 The frontal plate is wider than the supraorbitals. Gastrosteges, one 

 hundred and fiftj^ eight; urosteges, sixty-seven. 



Measurements. — Total length, 405 mm.; of tail, 10") unn. 



The dorsal stripe, as in E. eqiies, occupies but a single row of 

 scales. The lateral strii)e occnjiies the adjacent edges of tlie second 

 and third rows. The entire first row is covered by a broad brown or 

 black band, which defines the lateral light band very distinctly below. 

 This is not seen in either of the species above named. There are two 

 rows of black spots between the dorsal and lateral bands, but the keels 

 of all the scales involved in them are brown or yellow. There are no 

 sj)ots below the lateral light line, either on tlie neck or elsewhere. A 

 large nuchal black spot, which is notched behind by the median l)and. 

 Fifth superior labial yellow; the sixth black, with a yellow spot in the 

 superior anterior corner. Seventh, black-edged in front; others black- 

 bordered behind. A yellow postoral spot. Head above black or 

 brown; lower surfaces uniform greenish-yellow, except tail, which has 

 a median dark line below. Occipital spots very indistinct. 



This handsome species has been sent me from Pueblo and central 

 Mexico and from Zacualtipan Hidalgo. The typical sjiecimen was 

 received from Dr. I^uges, of (luanajuato, but the exact locality is 

 unknown. It may enter the Nearctic fauna.

Prof. O. P. Hay' gives the following account <»f Ihe habits of Eutw- 

 niu Kirtalis sirtalis: 



As to E. 8. sirialis, Trol'. 1'. W. Putnam -' states that a I'emalo takeu July 22 contained 

 forty-two nearly developed young. Each of these was 5 i inches long. The mother 

 snake was 35 inches long. Dr. J. Schueck, of Mount Carmel, Illinois, writes ' that 

 seventy-eight were taken from a female. He implies that he saw this done. C.
