40 BRACHYPODELLA. 



maugeri Wood, copied in my pi. 18, fig. 24, resembles rufila- 

 bris, but it has hitherto been referred to various other forms 

 of the genus, and I feel no certainty that it was drawn from 

 this rather than some other of the numerous closely-related 

 forms. 



I refer here, with some doubt, two of Pfeiffer's figures of 

 C. blandiana, copied on my pi. 16, f. 25, 26. 



20d. Yar. leucostoma Pilsbry, n. v. 



Shell with the last two whorls obese, the spire conic and 

 strongly tapering, as in other forms of the species; pale yel- 

 lowish or gray-white, with an inconspicuous white subsutural 

 line and a rapidly- widening opaque- white band at the keel; 

 lip white. Sculpture as in var. quadricolor. 



This variety from Egg Hill, Portland, is exactly like var. 

 quadricolor except in color. The pure white lip separates it 

 from var. rufilabris C. B. Ad. Described from the collection 

 of Mr. P. W. Jarvis.
