190 BULLETIN OF THE 



Euparypha Tryoni, Newc. 



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. alhida. Uniform creamy, and sometimes milk-white above and be- 

 neath, and without band. 



Var. suhcariyiata. 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 5| 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, Val. 



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,.j66.) 

 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 H. (Pomatia) pomatia, and it 

 may possibly be an introduced form. //. 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 Puehla, 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 Bnffoniana was figured 

 as aspersa by Dr. Binney in Volume III.
