如果上圖是seashell2392所說的東京捲管螺 Kermia tokyoensis (Pilsbry,1895)
那與日本微小貝的圖片顏色差很大,於是我心中充滿懷疑(註:日本微小貝把發表者及年代標錯了)
https://bishogai.com/pic_book/data02/a3562.html
於是我想找原始文獻出來比對下,一看不得了,差更大,下圖5就是原始圖片
https://www.biodiversitylibrary.org/item/41228#page/213/mode/1up
然而,我眼睛瞄到原始文獻的圖4,疑? 會不會原始文獻有錯,其實是圖4才對。
從以下原始文獻文字描述看來,圖4比較像吔,與日本微小貝的圖比較接近,
不過話又說回來,東京捲管螺長度約7mm,而jbslms38這顆1cm,會是同一種嗎?
Shell fusiform, elongated, slender, dark chestnut-brown through-
out. Whorls 6, slightly convex, separated by narrowly impressed
sutures, the earlier 2 whorls smooth, the remainder strongly latticed.
Spirals 15 on body-whorl, strong, equal and continuous; longitudi-
nal ribs 22 on last whorl, about as high as the spiral cords, but
wider and more rounded, disappearing on the very short canal.
Penultimate whorl! with 6 spiral cords. Aperture three-sevenths the
total alt. of shell. Outer lip thickened by a rounded varix, within
crenulated by short lire; the anal notch deep, narrow and rounded,
separated from suture by a heavy callus. Canal short and straight.
