Paraphaedusa schwaneri (Martens, 1867)
“Die äussere Gestalt dieser Schnecke ist ähnlich der von Cl. moluccensis, aber ihre Oberfläche mehr glatt und glänzend. Der ursprüughch violette Fatlen der Naht erscheint bei etwas verbleichten Exemplaren rein weiss.” (Martens, 1867)
“Proxime affinis Cl. (Euphaedusae) cumingiana Pfr. Insularum Philippinicarum et Moluccarum, sed colore pallidiore, papillis suturalibus nullis, aperture angustiore, peristomate non expanso, lam. Subcolumellari emersa bene distincta.” (Boettger, 1889)
Martens (1867) original descriptions on Clausilia schwaneri – “Testa conico-turrita, levissime striatula, nitida, corneo-brunnea, sutura violaceo-marginata; spira sensim attenuata, apice obtusula: anfr. 10-11, convexiusculi, ultimus penultimo paulo angustior: cervix rotundatus, paulo distinctius striatus; apertura piriformis, intus cornea; lamellae validae, compressae, divergentes, infera arcuatim descendens, supera marginem attingens ; lunella distincta: plica palatalis unica supera, elongata: subcolumellaris emersa: peristoma continuum, tenue, album. undique expansum.”
Boettger (1889) original descriptions on Clausilia (Euphaedusa) dohertyi – “T. vix rimata, clavato-fusiformis, gracilis, solidula, pallide corneo-lutea, ad suturam albidocingulata; spira elongate-turris; apex acutiusculus, submamillatus. Anfr. 9 ½ lente accrescentes et laxe volute, convexiusculi, sutura impressa simplici disjuncti, striatuli, ultimus praecendente angustior, cervice distinctius costulato-striatus, basi rotundus nec compressus nec carinatus. Apertura anguste-piriformis, breviter solute sed superne recedens, sinulo sublimi; peristoma undique incrassatum sed non expansum et perparum solum reflexum, margine sinistro bene curvato et media parte subprotracto, dextrostrictiuscule descendente. Periomphalum callosum, angustum, subplanum. Lamellae sat validate marginales, supera perobliqua, intus altior, cum spirali contigua vel continua, infera oblique ascendens sigmoides, a basi intuenti spiraliter intrans, subcolumellaris longe emersa. Apparatus claustralis lateralis, plica principalis modica profundissime sita, ventrilateralis, palatals verae 2 breves, principali paeallelae, superior duplo longior quam inferior.”
Loosjes (1953) descriptions on Paraphaedusa schwaneri – “Shell small, turreted fusiform, rather solid, reddish-brown, horn-coloured, glossy, transparent. Spire rather slender, usually with straight lateral outlines. Whorls 9 to 10, rather convex, almost smooth, fine growth-lines may be visible near the suture, distinct striae are only present on the last whorl near the aperture. The nuclear whorls are rather narrow, they sometimes form a little cylindric apex. They are often cream-coloured, as is also a narrow band on every whorl along the rather deep suture. The last whorl is rather flat dorsally, compared to the preceding whorl, which is distinctly swollen. The neck is very slowly and regularly bent towards the base of the aperture. The aperture is pear-shaped, triangular, yellowish within. It has a somewhat pointed sinulus, which is not very high. The base of the peristome recedes from the vertical plane. The peristome is whitish, thickened, not reflected, its upper margin is, at the top of the sinulus, scarcely clear of the preceding whorl. Usually the upper margin is faintly incised in the place where it is in contact with the superior lamella; there may be a distinct, rather broad incision in some cases, however, from the sinulus the outer margin bends down regularly and distinctly, whereas the parieto-columellar margin usually runs to the right while slowly descending. The base of the peristome is semi-circular. Lamella superior is strong, reaching the margin, it is continuous with the spiral lamella or only just clear of it. The spiral lamella gradually increases to be highest in the lateral right position, than it decreases rapidly to end at the ventral side, almost together with the two other lamellae. Lamella inferior is visible in the aperture as a low fold on the columella, its outer end reaches the margin. At ¾ of the visible part of the columella the inferior lamella increases rapidly, its thickened edge turning inward almost horizontally. In a dorsal position it is highest, forming the wing-like structure characteristic for Paraphaedusa, which has a regularly rounded top. The lamella inferior decreases rapidly, ending at the ventral side. Lamella subcolumellaris reaches the margin, the inner end may run a little beyond the ends of the other two lamellae. The closing apparatus lies at the right side or a little ventrally from it. The plica palatalis principalis runs from dorsal to latero-ventral, it is about 3/8 whorl long. Below it are two rather short palatal plicae, the upper one near the principalis, diverging from it; the lower one above the closed umbilical slit runs more or less parallel to the principalis; both plicae are connected at their outer ends by a faint or distinct callous lunella-like patch. The plate of the clausilium is triangular, widest near the apex; there it is also most distinctly curved; it is not incised at the palatal side of the apex, it has therefore no palatal lobe. It has a distinct angle at the columellar side, where it merges into the pedicle. The dimensions of the plate are: length 1.9, width 1.4 mm.”
