UROCOPTIS (AUTOCOPTIS) BEATENSIS. new sp«cies 



Plate 1, Figuke 11, 13 



Shell pupoid, the apex of the spire decollated, the upper half 

 darker than the anterior. The whorls are slightly rounded, ap- 

 pressed at the summit and separated by a poorly impressed suture. 

 The surface is almost polished, being marked by fine, retractively 

 slanting, incremental lines and microscopic spiral striations only. 

 The base is short, strongly rounded, with an umbilical slit, and an 

 obsolete cord marking the line at the junction of the outer and basal 

 lip. The umbilical area of the last whorl is marked by rather regu- 

 lar threadlike riblets, which are about one-half as wide as the spaces 

 that separate them. These riblets become more closely approxi 

 mated toward the aperture. The last whorl is solute for about one- 

 tenth of a turn, and the aperture is broadly flaringly expanded. It 

 is obliquely oval, with the outer edge of the peristome decidedly 

 thickened all around. The pillar is slender, solid, and twisted and 

 expanded into a lamella on the last half of the last turn. 



Type.—ThQ type, U.S.N.M. No. 403913, has 7.5 whorls remaining, 

 and measures : Length, 23 mm ; diameter, 9.3 mm ; greatest diameter 

 of aperture 8.1 mm; height of aperture, 7 mm. 



Remarks. — Nine topotypes were obtained, the largest of which has 

 8 whorls remaining, and measures: Length, 21: mm; diameter, 10.2 

 mm; greatest diameter of aperture, 8.8 mm; height of aperture, 8 

 mm. The smallest has 6.5 whorls remaining, and measures : Length, 

 19.6 mm ; diameter, 8.9 mm ; height of aperture, 6.9 mm. The border 

 of the aperture being broken prevents our giving the greatest diam- 

 eter of it.

 pp. 104, 105. 



Shell fusiform, flesh-colored with a brownish flush. Nuclear 

 whorls 2, the first smooth, the second showing the beginning of the 

 axial riblets. Postnuclear whorls increasing steadily in size from 

 the first to the sixth whorl, after which they again decrease in width 

 toward the base. The early postnuclear whorls are very strongly 

 rounded, the median ones less so and the later ones very slightly so. 

 The last one is slightly exserted at the basal carina. These whorls 

 are marked by slender, slightly flexuose, retractively curved axial 

 riblets, those of the early turns being almost sublamellar while those 

 on the later whorls are more threadlike but more elevated than an 

 ordinary thread would be. They are a little less wide than the spaces
