BATEACHIA URODELA. f 



Many specimens of this species were collected in 1841, at Nisqually, 

 Puget Sound (Oregon), and San Francisco (California). The sketch 

 from life was made from Puget's Sound specimens by Jos. Drayton.

Fig. 2, exhibits the under surface of the same specimen. 



Fig. 3, is an outline of the head, seen from above, showing the wide 

 interocular space.

Fam. PLETHODONTIDAE. 



Vomero-palatine teeth disposed upon one series across the posterior 

 extremity of the vomerine bones, thus constituting a cross band 

 behind the inner nostrils, in front of the palate. Sphenoid often- 

 times covered with teeth. Vomerine bone broad and short. Skin 

 generally smooth, rarely granular, and without any series of pores.
