Paraboysidia neglecta van Benthem Jutting, 1961
“It differs from P. laidlawi in being not so slender, the last whorl bulging out more in the profile of the spire. The lamella in the parieto-angular corner may better be called the angular lamella (not parieto-angilar lamella). Consequently the parietal lamella is missing. The adnate peristome characterises the species as a Paraboysidia.” (Benthem-Jutting, 1961)
Benthem-Jutting (1949) descriptions on Hypselostoma laidlawi (non laidlawi Collinge, 1902) – “Shell very small, conical, white (perhaps a bleached specimen?), with delicate spiral lines, about 20 visible on the last whorl, and 8 on the penultimate one. This spiral sculpture is crossed by fine growth lines. Not tansparent, without lustre (perhaps on account of not too fresh condition?) Whorls 4 ½ , regularly increasing in size. Profile of each whorl evenly rounded. Suture well impressed. Top blunt, umbilicus wide, showing all previous whorls. Aperture slightly oblique, provided with 2 teeth only: one parieto-angular lamella and one upper palatal fold. Peristome continuous, somewhat thickened and reflected, almost entirely adnate to the previous whorl.”
Hypselostoma laidlawi (non laidlawi Collinge, 1902) – “Dimensions: Height – 1.2 mm; Breadth – 1.3 mm; Height of aperture – 0.5 mm; Breadth of aperture – 0.5 mm. (Benthem-Jutting, 1949); Paraboysidia negleta – “Dimensions: Height – 1.5-1.8 mm; Breadth – 1.7-1.9 mm; Height of aperture – 0.7-0.8 mm. (Benthem-Jutting, 1961)
