Plate II. Fig. 9. 



It is about the size and form of B. Mooreanus, but rather more slender and 

 elevated. The surface is not smooth, as in the other American BuUrauli, but 

 strongly ribbed-striate longitudinally. The apex is blunt ; peristome thick-

 aperture is less than half the length of the shell ; color brownish, corneus 

 somewhat translucent, the riblets opaque white. Height 22 mm., diam. 

 10 mm. ; height of aperture lOi mm., diameter 7 mm.

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 cy clops. 



Pupa Coloradensis, Cockeeell. 



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 browTi, one long, 

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

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

 more striate, and slightly narrower. (CockereU.)
