before its insertion. Length 5y 2 , diam. 1%-1% mm. Ban- 

 atus, Kuester coll." 



In Westerlund's latest account he says: "Ap. margine 

 exter. superne incisura profundiuscula munita," where be- 

 fore he had said "margine columellari. " Also in the German 

 text (1887) he said: "Aussenrand oben ziemlich tief aus- 

 gebuchtet." This is the condition in all of the group, so 

 that his first statement was apparently an error. Nothing 

 was said of teeth, which presumably are as described by him 

 for the typical form, 1-2 slender parietal, and 1 columellar 

 lamella. 



Sturany and Wagner do not consider arm at a and cccsa to 

 be valid races. 



12. Agardhia stenostoma (Flach). 



Shell rimate, narrow, cylindric, at the apex obtuse, nar- 

 rowly costulate, similar in stature to parreyssii, a little 

 smaller. 6% slightly convex whorls. Differs primarily by 

 having the neck before the aperture very strongly and 

 abruptly constricted as far as the sinulus; the aperture is 

 very narrow, strongly oblique, outwardly sinuate ; outer lip 

 simply expanded ; 3 parietal folds, the middle one prominently 

 arcuate. Length 4.2, diam. 1.2 mm. (Flach).

This unfigured form has not been noticed by subsequent 

 authors. 



13. Agardhia truncatella (Pfr.). PI. 19, figs. 2, 3, 4, 5. 

 Shell rimate, cylindric, obtuse at apex; thin, diaphanous; 



vertically elegantly costulate; waxy whitish; 6 to 7 rather 

 flattened whorls, the last rotund basally, slightly over a fourth 

 of the total length. Aperture subvertical, obliquely semi- 

 oval, toothless; peristome nearly simple, a little reflected, the 

 right margin arching forward, columellar margin shorter. 

 Length 4; diam 2 mm.; aperture 1% mm. long (Pfr.).
