Fig. 11 C – E

Glessula woodthorpei Godwin-Austen, 1920: 58, pl. 162, fig. 19. Type locality: Shan States [Shan State, Myanmar].

Type specimens.

Syntypes NHMUK 1903.7. 1.1628 [re-registered in error as 1986051] (9 shells; Fig. 11 C – E ) collected by Woodthorpe ex. Godwin-Austen collection from Shan States.

Other material.

NHMUK 1903.7. 1.3655 (2 shells) collected by Woodthorpe ex. Godwin-Austen collection from Siam N. W. Boundary.

Diagnosis.

Shell oblong conical and regularly attenuated; spire high conical; embryonic whorls rounded; subsequent whorls nearly smooth and equally spaced radial ridges appeared near suture. Suture impressed and whorls slightly convex. Aperture ovate; columella strong, concave, and truncated.

Distribution.

This species is known from Shan State, Myanmar with an additional record from Thailand.

Remarks.

Godwin-Austen (1920) indicated that nine specimens with the catalogue number ‘ Type No. 1682 B. M. ’ were examined. The species description included one set of measurements and an illustration of one shell. The NHMUK type collections contain a lot of nine specimens from the Woodthorpe collection with a label in Godwin-Austen’s handwriting stating ‘ Type’. The measurements of the specimen with red wool inside the shell are close to the measurements given in the original description. It likely corresponds to the illustration of the species provided in the original description and it herein figured (Fig. 11 C ) along with other shells (Fig. 11 D, E ) from the same syntype lot.

Godwin-Austen separately mentioned (1920: 58) another bleached specimen lot NHMUK 1903.7. 1.3655 (2 shells) from Thailand. However, this specimen lot does not form part of the type series of this species.
