The specimens in the collection of the California Acad- 

 emy of Sciences agree perfectly with Prof. Cope's original 

 description, except in the number of scale rows and 

 loreal plates. One of the seven has twenty-one rows of 

 scales, two have twenty-two, and the remaining four have 

 twenty-three rows. Each of four of these specimens has 

 a small plate in the notch between the second and third 

 supralabials, below the posterior loreal, and in front of 

 the two inferior preoculars. The largest individual (No. 

 482) is 990 mm. in total length, 155 mm. representing the 

 tail. It is a female, and contains eggs measuring about 

 9x21 mm. 



The types of this species were secured by Mr. Xantus 

 at Cape San Lucas. Mr. Belding found other speci- 

 mens at La Paz, in 1882.
