nodulous การใช้

The nodulous papillae are, however, much larger in proportion to the size of the shell, and, in consequence, fewer.
This species differs from " Fusiturricula fusinella " by the obliquity of the ribs and the disparity in size between the peripheral spiral cords, which are quite equal and equally nodulous in " F . fusinella ".
G . W . Tryon correctly preserved the genus for smooth specimens with a short body whorl, long spire, nodulous shoulder, no spiral sculpture, a wide, deep anal sulcus adjacent to the suture and, in the completely adult, a marked subsutural callus on the body.
