190 BULLETIN OF THE 
Euparypha Tryoni, Newco. 
Mr. Hemphill has thus described several varieties. (See Zoe, Vol. I. pp. 331, 
332.) 
Var. varius. The upper or dark zone is of a lighter shade of bluish brown 
or chestnut than the type, and is flecked and sprinkled with ashen white; 
band at the periphery dirty white beneath. 
Var. nebulosa (Plate IV. Fig. 5). Lighter colored above than var. varius, 
marbled and clouded with various patterns of dark brown and dirty white ; 
dirty white beneath. 
Var. fasciata (Plate IV. Fig. 6). Uniform light chocolate above and be- 
neath, with a dark band at the periphery. 
Var. Californica, Creamy buff-color, darker above than below the periph- 
ery, very faintly banded. 
Var. albida. Uniform creamy, and sometimes milk-white above and be- 
neath, and without band. 
Var. subcarinata. Among the subfossils that occur on Santa Barbara Island 
we find a form of H. Tryoni which adds an interesting link to its history and 
to its present form. It may be characterized as follows. Shell depressed glo- 
bose, consisting of about 53 whorls, the last subcarinated at the periphery; in 
other respects closely resembling the recent form. Greater diameter 23.15 and 
20.11 mm., largest and smallest specimens. 
Pomatia Humboldtiana, Vat. 
Texas, at Altuda, at an elevation of 5,000 feet, where it, a single specimen in fair 
condition, had been thrown out with soil by a prairie dog. (Mus., No. 118,366.) 
William Lloyd. 
This species has not before been reported from any locality within the territory 
of the United States. It was described from Mexico, where it is found in the 
neighborhood of the city of Mexico, and in other localities. The national collec- 
tion contains several examples from the Real del Monte. It has a pretty close 
resemblance to some of the varieties of the European ZZ. (Pomatia) pomatia, and it 
may possibly be an introduced form. H. pomatia has for centuries been esteemed 
as an article of food in various parts of Europe, and was regarded as a dainty by 
the ancient Romans. It was propagated and raised in large quantities for their 
use, and specially fed on certain plants to give the flesh a particular flavor. 
Unmistakable specimens of another favorite edible snail common to Europe, 
H. (Pomatia) aspersa, is found in Mexico, and examples from Puebla, in the prov- 
ince of Puebla, Mexico, were presented to the National Museum by the Mexican 
Geographical Commission a few years ago. The presence of these two forms most 
certainly suggests the question as to whether they were not introduced by the 
Spaniards many years, centuries, ago, either for food purposes or incidentally in 
the routine and accidents of commercial intercourse. 
The above was published by Stearns in Proc. U. S. National Museum, Vol. 
XIV. p. 96, 1891. It will be remembered that Helix Buffoniana was figured 
as aspersa by Dr. Binney in Volume III.
