AURIS-EUDOLICHOTIS. 119 



A. MIDAS Albers. PI. 43, figs. 64-68. 



Shell rimate-umbilicate, ovate, rather thin. Fleshy-white, with long, 

 oblique purple-brown stripes spotted with light, and usually with some 

 scattered dark dots, or else red-tawny, becoming lighter on the back 

 and variegated with purple-brown there. Surface smoothish, the 

 next-to-last whorl rib-striate, last whorl with faint growth- wrinkles 

 and a microscopic superficial granulation. Spire varying in length ; 

 whorls about 5, slightly convex, the suture margined, at least on 

 latter part of body-whorl. Last whorl not perceptibly compressed 

 behind lip or pinched at base. 



Aperture over half the alt. of shell, long-ovate, maculated within. 

 Peristome white, the outer lip narrowly reflexed above, broadly 

 below, basal lip broadly reflexed with recurved edge ; columella with 

 a long, low, spirally ascending fold above, separated from parietal 

 wall by a shallow furrow. Parietal callus a mere transparent film. 



Alt. 50, diam. 21 ; alt. of aperture, 29 mill, (type specimen). 



Alt. 48, diam. 23 ; alt. of aperture, 27 mill. 



Alt. 43, diara. 25 ; alt. of aperture, 28 mill.

The typical form is slender, light colored with few dark oblique 

 stripes and scattered dots (figs. 64, 65) ; others have much heavier 

 marking (figs. 66, 67) ; and some specimens are a beautiful reddish 

 color (fig. 68), with more or less dark marking on the back. The 

 spire may be quite long and the figure of the shell slender (figs. 64, 

 67), or the spire may be short, body- whorl obese (figs. 66, 68). 

 These variations are well connected by intermediate examples. 

 Von Martens has referred this species to Anthinus, but it is very 

 closely allied to A. sinuatus, and has no intimate relationship with 

 A. multicolor, the type of Anthinus. 



Var. SPECTRUM Albers. PI. 43, figs. 69, 70. 



Shell perforate, fusiform, rather thin, closely striate and submal- 

 leate ; tawny-flesh colored, with livid streaks and scattered chestnut 

 dots. Spire long-conic, rather acute ; suture somewhat margined. 

 Whorls 5, rather convex, the last as long as spire, attenuated at 

 base, and somewhat compressed.
