aperture is less than half the length of the shell ; color brownish, corneus 
somewhat translucent, the riblets opaque white. Height 22 mm,, diam.

A new figure is given. 
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.

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 ;

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,
