from their subterranean haunts, and a good many were 

 found in the northern part of the city at the settling reser- 

 voirs of the city water works at Bissell Point. Most of 

 them were dead, however, when discovered. Dr. P. K. 

 Baer gave me two specimens, which his son had caught 

 in their yard on top of a hill near O 'Fallon Park. I also 

 found one in a quarry south of the Eiver Des Peres in St. 

 Louis County. The species seems to be nocturnal and of 

 burrowing habit. 



Genus haldea.

 frontals large, entering together with the loral into the orbit, thus 

 suppressing the anteorbitals. Postorbital one. Two nasals. Dorsal

 divided. Vertebral column with hypapophyses throughout.
