Var. STRIGOSA Gould (typical) Vol. Ill, pi. 10, figs. 32, 33, 34. PL 



42, figs. 7, 8, 9. 



Far to the westward of all other colonies of strigosa, at Spokane, 

 Washington, is found a variety remarkable for its elegant sculpture 

 and coloring. The form is rather depressed, surface finely wrinkle- 

 striate and decussated by finer spiral incised lines. The color is 

 whitish, much stained and mottled with fleshy-brown above, or 

 entirely flesh-brown with white strise ; base whitish in adults, flesh- 

 brown in the young. Most specimens show many dots of trans- 

 lucent brown. There are generally two bands, one above, one 

 below, but both are frequently lacking, and many specimens show 

 additional bands on the base. The whorl descends toward the 

 aperture, which is elliptical. This form is really the original and 

 therefore the typical strigosa of Gould ; but Hemphill has given to 

 Spokane Falls specimens the name var. parma (pi. 42, figs. 7, 8, 9). 

 Numerous specimens have been collected and distributed to Amer- 

 ican collectors by Mrs. Mary P. Olney, of Spokane, Wash., to whom 

 I am indebted for those figured. 



Var. JUGALIS Hemphill. PI. 41, figs. 93, 94, 95. 



A very broad, depressed form, from Salmon River, Idaho. It is 

 more or less distinctly 2-banded, the umbilicus is wide, and the whorl 

 descends deeply at the aperture. The surface is coarsely striated, but 

 not ribbed. HemphilFs var. intersum (pi. 41, figs. 91, 92) is a 

 smaller form of this in which the surface is generally more suffused 

 with purple-brown, and is more distinctly costulate, sometimes as 

 distinctly as in var. binneyi. 



The following so-called varieties have been given names. They 

 have no varietal standing ; and there are several thousand forms of 

 strigosa equally deserving of names : 



Form depressa Ckll. is a flattened form represented in vol. Ill, 

 pi. 10, fig. 36. FoTmfragilis Hemph. (pi. 41, figs. 5, 6) is moder- 

 ately elevated, rather thin and somewhat translucent brownish or 

 flesh colored, with two bands ; from near Franklin, Idaho. Form 

 carnea Hemph. is generally bandless, fleshy-brown above, usually 

 whitish below, finely striated ; from near Salt Lake. Hardly worth 

 a name. Form rugosa Hemph. is a large robust variety with very 

 convex whorls, from New Brigharn City, Utah. A depressed form 

 from near Logan, Utah, has been called var. albida Hemph. A form 

 connecting with var. binneyi has been named buttoui Hemph. (pi. 

 41, figs. 97, 98). It is from Box Elder Canon, Utah, and is often
