在预期的压缩标准描述的Nummulites物种一般，本文提出了一个更广泛的使用的图形表示的基本诊断功能的赤道部分的microspheric代。这个综合图由四条曲线组成：1）众所周知的弯曲曲线（连接连续螺旋的半径），它大致反映了螺旋的开口步骤; 2）在相同的螺旋尺度上，每个螺旋的腔室数量的文件; 3）腔室腔的高度; 4）这个相同的高度加上螺旋索或螺旋片的厚度。后两条曲线代表对螺旋台阶的分析，限定了一条不规则的带状物，该带状物描绘了整个脊柱上脊髓或椎板的厚度。在同一横坐标上的四条曲线的组合揭示了尖塔的过程中（或者说是拿破仑的生活过程中）的某些突变和趋势，这些突变和趋势迄今为止还没有被记录下来。
In anticipation of a condensed standard description of the Nummulites species in general, this article proposes a more extensive use of the graphic presentation of essential diagnostic features of the equatorial section of the microspheric generation. The comprehensive graph in question consists of four curves: 1) the well-known winding curve (connecting the radii of the successive whorls), which roughly reflects the opening step of the spire; 2) the file of the numbers of chambers per whorl on the same scale of whorls; 3) the height of the chamber lumen; and 4) this same height plus the thickness of the spiral cord or lamina. The latter two curves, representing an analysis of the spiral step, confine an irregular ribbon which delineates the thickness of the spinal cord or lamina over the whole spire. The combination of four curves over the same abscissa unveils certain breaks and trends in the course of the spire (or the course of the specimen9s life) which hitherto remained unrecorded.
