Plate I. Fig. 6. 



Rhodea Californica. 



This extralimital species has actually been received by Dr. Cooper from. 

 Lower California. (Proc. Cal. Acad. Nat. Sci., 1891, p. 102.) It had been 

 quoted as an Achatina from Monterey. (See Vol. V.) 



Pupa Californica. 



Dr. Sterki in Nautilus, Vol. IV. page 7, mentions a variety, elongata, from 

 San Clemente Island ; on page 18, varieties trinotata, Diegoensis, and cyclops. 



Pupa Coloradensis, Cockerell. 



Shell brown, shiny, thinnish, striate, especially on penultimate whorl ; out- 

 line oblong-oval, barrel-shaped ; apex blunt ; whorls 4 ; aperture pyriform ; 

 peristome brown, thick, continuous by a well marked callus on parietal wall ; 

 outer lip not constricted. The teeth within the aperture are brown, one long, 

 one on parietal wall, one on columella, and two (the lower one largest) on outer 

 wall. Long. 1^, lat. 1 mm. Allied to P. corpulenta, but decidedly smaller, 

 more striate, and slightly narrower. (Cockerell.)
