這樣看來要趕快遠征桃園了.看了jbslms38貼的這些殼,手好癢阿! 有獨無偶,車城最近蓋起了夭壽的遊艇碼頭,旅館也在施工,嚴重威脅附近的海岸貝類,也希望有志之士趕快來見證.

這種小型捲管螺殼長約1cm,在桃園觀音常見,可惜不易找到螺塔完整的,因為遭到污染,殼色明顯淡化.煩請知道的貝友告知名稱,謝謝!

如果上圖是seashell2392所說的東京捲管螺 Kermia tokyoensis (Pilsbry,1895)
卻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.

於是我再從原始文獻中找出圖4的文字描述
Clathurella gainesii(後來改為 Etrema gainesii)
Shell elongated, turrited, corneous-brown, the interstices of the
latticed sculpture dark brown. Whorls 7, very convex, separated
by deep sutures; the earlier portion of spire attenuated. Sculpture
consisting of strong, broadly rounded longitudinal folds (12 on last
whorl, becoming obsolete on the base) crossed by narrow but strong
spiral cords separated by intervals greater than their width, contin-
uous over the longitudinal folds but stronger between them, in num-
ber 14 on last whorl, 4 on penultimate whorl. Aperture contained
2% times in length of shell; outer lip thick, narrowly varixed out-
side, having several rather strong teeth within; anal notch deeper
than wide, oblique, separated from suture by a thin callus only.
Anterior canal very short. Alt. 6 1/4, diam. 2 2/3 mm.
從殼形為塔狀, 縱肋比Kermia tokyoensis少, 長度也略短, 這幾個特徵看來, 反而比較像圖5
原本只是想確認陳老師的標本是不是 Kermia tokyoensis, 無意中卻發現了原始文獻圖片的錯置。

回到主題: jbslms38這顆1cm，是不是東京捲管螺 Kermia tokyoensis ? 我認為是
關鍵在原始文獻有這段文字: Spirals 15 on body-whorl, Penultimate whorl! with 6 spiral cords.
倒數第2層有6條橫紋，最後一層有15條，jbslms38的標本雖然大了一點，但完全符合這樣的描述。
