form; light yellowish straw-colored, with or without a dark band; 

 surface rudely striate and cut by irregular spirals into small 

 granules; not malleated or slightly so. Whorls 5%; outer lip 

 thickened, hardly expanded, white, basal lip expanded and a trifle 

 impinging on umbilicus, which is deep and rather widely open, 

 somewhat as in Polygyra kiawaensis." — Pilsbry, Nautilus 9:72.

Notes on the Washington Sphaeria and Pisidia, with descrip- 

 tions of new species. Nautilus 9:97-99. Mentions Sphgerium 

 occidentale, raymondi; Pisidium idahoensis, variabile, compres- 

 sum, abdition, ultarmontanum, and numbers 1688-1691. 



1688 Sphseriiun primeamini Classen. 



Shell large, equilateral, dark brown or black with lighter, 

 beaks, shining. Outline rhomboidal, a little more elongated and 

 the ends more rounded than S. rhomboideum Say, but the dorsal 

 aspect very much like that of the species. The full, rounded beaks 

 make the vertical section broadly cordate. One specimen, chest- 

 nut colored and with yellow border, is so close to S. rhomboideum 

 as to be held in doubt." — Roper. 



1689 Sphserium dentatum Hald. 



Spokane Falls, Wash. (Mrs. Mary P. Olney), "handsome, 

 bright green shells, differing only in color from brownish Oregon 

 specimens, are doubtfully referred here" (Roper). 



1690 Sphjerium nobile Gould. 



Abundant in small streams, Seattle, Wash. (Roper). 



1691 Pisidium Randolphii Roper. 



"Shell rounded oval, moderately inflated, anterior end elon- 

 gated and perfectly rounded, no angle indicating the junction of 

 the anterior and basal margins; posterior margin sloping abruptly 

 from the very short hinge margin; beaks decidedly posterior, 

 fairly prominent; surface very finely and evenly striated, polished, 

 of a most peculiar greenish-yellow color, different from other 

 Pisidia, but much like some Corbiculas. Lon. 0.18, lat. 0.14, 

 diam. 0.1 inch." — Roper. 



Type locality: — Seattle, Wash.
