LORQUINIA 
Usually 20 to 30 mm. in diameter. This, one of our largest native 
snails, has been collected in Eaton's Canyon, Sawpit Canyon, and in 
the Arroyo Seco near Busch's Gardens. 
As a species it is quite widely distributed though seldom found in 
large colonies. I have specimens from Fresno, San Bernardino, San 
Diego, Orange, and Los Angeles counties. 
Bpiphragmophora fraski, Newcomb. Trask's snail. Similar to 
the last in color, but usually slightly smaller and flatter and with 
finely incised spiral lines instead of the hammer-marks of that species. 
Specimens have been collected in Millard's Canyon, in the Arroyo 
Seco near Busch's Gardens, in Los Angeles, and at Point Firmin. 
Bpiphragmophora cuyamacensis, Bartsch. A recently described 
species, in which the surface of the shell is covered with minute pus- 
tules instead of incised spiral lines Hke those of traski. One imma- 
ture specimen that is apparently of this species has been found near 
the Dawn Mine, Millard's Canyon. 
Glyptostomai newberryanum, Binney. Newberry's snail. An- 
other of our large native species. Its surface is smooth, almost pol- 
ished in appearance and of a rich brownish-red color. The shell is 
rather flat and the lip is always sharp, never expanded. This species 
has been found in Millard's Canyon, the Tejunga, and on the hills at 
Dominguez Junction. It is found in San Diego County, possibly far- 
ther south. So far as I know, it is not found north of the San 
Gabriel Range. 
Helix aspersa, Muller. The spotted snail. This common garden 
pest is too famihar to need description. This species was originally 
introduced from Europe by French vineyardists who used it as food. 
It has spread rapidly and specimens have been brought in from Saw- 
pit Canyon, although it usually stays near cultivated gardens. 
Pyramidula. Four small, white shells resembling* Pyramidula 
cronkhitei, Newcomb, were found in the leaf mould in Millard's can- 
yon. They are about 6 mm. in diameter and the four whorls are 
crossed by numerous heavy ribs. 
Punctum conspectum, Bland. This tiny brown snail, a little 
larger than a pin-head, has been found in devaying leaves in the 
Arroyo Seco near Busch's Gardens. It is common in lawns and fern 
boxes in various parts of Los Angeles. 
Vallonia pulchella, Muller. A tiny, smooth, white snail that is 
commonly found with the last. It is so transparent that with the aid 
of a 20 diameter Coddington lens I have watched its heart beating. 
There are several other species reported from the San Bernaraino 
mountains and more intensive collecting will probably reveal many 
of them in the San Gabriel Range. I shall greatly appreciate any 
further material especially that from the upper reaches of the can- 
yons.
