Sagittal section: KMNH IvP 400,364[HZ00100G-0003-l]Description: Misellina claudiae (Deprat) has a small,short ellipsoidal shell with the coiling having a straightaxis, and broad, rounded to umbilicated poles. The obtained specimens of six and a half volutions are 1.63 to1.68 mm long and 1.18 to 1.23 mm wide. The form ratioranges from 1.35 to 1.43, averaging 1.39 for the twospecimens. The inner two volutions are nearly spherical,with rounded poles, to somewhat umbilicate. The axisof the succeeding volutions extends gradually. Averageratios of the half-length to the radius vector of the first tosixth volutions for the two specimens are 0.87, LOO, 1.04,1.23, 1.31 and 1.28, respectively.The proloculus is spherical and rather large for thisspecies, with an outside diameter of 0.13 to 0.14 mm.Expansion of the shell is slow in the inner volutions, andbecomes gradually more rapid outwards. Average radiusvectors of the first to sixth volutions for the two specimensare 0.11, 0.17, 0.24, 0.32, 0.42+ and 0.57mm, respectively.The spirotheca of the inner two volutions are composed of a structureless layer, and the succeeding onesconsist of a tectum and keriotheca. The thicknessincreases as the shell grows, with the thickness of the firstto sixth volutions of two specimens averaged at 0.015,0.023, 0.028, 0.033, 0.038+ and 0.045+mm, respectively.The septa are completely unfluted throughout theshell. Septal counts of the second to sixth volutions inthe obtained sagittal section are 6+, 12, 13+, 20, and 21,respectively. The low and broad parachomata are welldeveloped throughout the shell.Remarks:The obtained specimens have a rather small
