1487 Pupa californica Rowell. 
“Wrom San Francisco. Several hundred examples of the well 
known form everywhere in collections. It may be regarded as 
typical, yet is somewhat variable in itself, as to shape of the shell 
and number and size of the lamelle; many specimens are more 
or less oblong or obovate, while the majority are rather cylin- 
drical; in some, the superior palatal lamella is very small and 
in a few even entirely wanting, while the apertural, columellar 
and inferior palatal seem to be constant, the first and last of them 
generally well formed, while the columellar may be small. In 
one specimen I saw a tiny but distinct supra-apertural, and in 
very many there is a small-nodule-like supra-apertural, close to 
the middle of the (outer side of the) apertural. So far I had 
thought this latter to be a special, distinguishing character of P. 
Rowelli Newc.’’—Sterki. 
1488 Variety elongata. San Clemente Island. 
‘‘A little smaller and generally more cylindrical than the type; 
a part are even long cylindrical, having the appearance of an 
Isthmia. The coloration is somewhat paler, and the lamelle are 
well-formed—elongata. Among the more than 100 specimens 
there were 5 different from the balance, and ranging with the 
following form.’’—Sterki. 
1489 Variety catalinaria. Santa Catalina Island. 
‘All the examples (about 200) are of quite a peculiar form: 
small, rather short, pale horn colored; shell thin, delicate; rib- 
like strie less numerous and relatively larger; the whorls are 
less high, which gives the shell a different appearance. All la- 
mellze are present and well-formed, specially the apertural. The 
shell is nearly exactly of the size and shape of Vertigo bollesiana 
Morse, from New York or Ohio, and also the lamelle are much 
alike. One peculiarity is that in about one-third of the examples 
a part of the shell is wanting, always on the side of the aperture, 
so that 3 or even 4 whorls are opened. This can hardly be acci- 
dental, and probably that part of the thin shell is worn off by 
friction in moving.’’—Sterki. 
1490 Variety trinotata. Monterey, Cal. 
“In size not much different from the type, yet a little smaller, 
and more generally obovate; the strie# are less coarse; the per- 
istome is slightly but distinctly expanded. There is no superior 
palatial lamella, and the 3 present ones are small, the columellar 
even a trace or wanting entirely.’’—Sterki. 
1491 Variety Diegoensis. San Diego, Cal. 
“The diminution of the lamelle is going on; none but the 
apertural is left in this variety—diegesis—and that even is quite 
small or a mere trace. In size and shape, the examples are not 
much different from the Monterey form, which is an intermediate 
one.’’—Sterki. 
This form I first found growing on Roccella tinctoria, near San 
Quintin bay, Baja California, and distinguished as Pupa orcutti 
(Pilsbry, ined.). Later, I found it near Ensenada, on Todos San- 
tos bay, Baja Cal., and near San Diego, Cal.—in both places on 
plants of Mesembrianthemum equilaterale.—Orcutt. 
1492 Variety cyclops. Rocklin, Placer, Co., Cal. 
‘Large, conic or ovate conic, or turriculate, umbilicated, rib-like 
strize rather strong; whorls 5, well rounded, with deep suture, the
