Original description of Conchothyra parasitica by Hutton, 1877:

• "The shell is at first spiral, afterwards convolute; the inner lip has a strong callosity which extends over the anterior end of the aperture; the right lip is expanded, sinuated, and recurved, forming a thick callus which joins that of the inner lip. In old individuals this callus entirely envelopes the whole shell."

Description of Conchothyra parasitica by Hutton, 1893:

• "Spire acute, of four whorls, shorter than the body whorl, apparently smooth. Incrustation smooth on the aperture, but rough with growth-lines on the exterior. Lobe of outer lip with nearly parallel sides, rounded at the end, and reaching nearly to the anterior end of the shell."

Remark: It was actually named by McCoy in ~ 1870, but without a description, so it was in effect a nomen nudum for a while. Hutton gave a description as a footnote in the 1877 publication and then subsequently published a second one in 1893.
