Glessula perlevisGodwin-Austen, 1920Fig. 10 D, E
Glessula perlevis Godwin-Austen, 1920: 59. Type locality: Shan Hills [Shan State, Myanmar].
Type specimens.
Syntypes NHMUK 1906.5. 5.89 [re-registered in error as 1986023] (5 shells; Fig. 10 D, E) ex. Godwin-Austen collection from Shan Hills, Burma.
Diagnosis.
Shell oblong ovate and regularly attenuated; spire high conical; apex rounded and blunt; subsequent whorls nearly smooth with very weak growth lines, and somewhat strong irregularly spaced ridges near suture. Suture impressed and whorls slightly convex. Aperture ovate; columella concave and truncated.
Distribution.
This species is known only from the type locality in the Shan Hills near Mandalay. The type locality noted by Godwin-Austen seems ambiguous because it was described as ‘ probably comes from the Shan State near Mandalay collected by Fedden’ (Godwin-Austen, 1920: 59).
Remarks.
Godwin-Austen (1920) described this species based on five specimens in the Blanford collection. The species description included one set of shell measurements, the number of specimens examined and the W. T. Blanford catalogue number ‘ Type No. 89.06.5.5 ’ (NHMUK 1906.5. 5.89), and there was no illustration of the shell. The NHMUK collections contain a type specimen lot consisting of five shells (2 matures + 3 immatures) with an original label stating ‘ Types’. The mature shells correspond well with the shell dimensions given in the original description and are illustrated herein for the first time.
