Habits.— On October 11, 1890, I wrote to Dr. L. Stej- 

 neger of tlie National Museum, upon request, what I knew 

 of this species. After a lapse of twenty years I have noth- 

 ing to add to what I wrote at that time, which was as fol- 

 lows: — "This snake is only found to my knowledge along 

 the river front of the city of St. Louis, near the Arsenal 

 ground. The place in which it is found covers a space 

 of about three blocks, and consists of an abandoned and 

 partly refilled quarry. Here they live among and under 

 the rocks, in the ground under bushes, feeding on worms 

 and insects — a fact which I ascertained by examining the 

 contents of their stomachs. They were once quite com- 

 mon — some thirty years ago — but are now getting scarce, 

 owing to the location being utilized for railroad iDurposes. 

 Having kept specimens in captivity, I am able to state 

 that this species is ovoviviparous, one of them having 

 brought forth as many as six young snakes, which were 

 90 mm. long."
