Types.

Sadia, E. Assam, leg. Ogle, NHMUK 1903.7.1.740. (4 syntypes, Figure 5A, 6A).

Diagnosis.

Shell middle sized, dextral, yellowish-reddish striped with moderately wide umbilicus and somewhat domed dorsal surface; callus strong, palatal plicae divided at their middle and the posterior fragments are connected by a ridge; parietal wall with a single curved lamella with posteriorly elongated upper and lower ends. Probably at least the upper elongation is homologous with the posterior denticle of other Endothyrella species.

Measurements

(in mm): D: 16.8-16.9, H: 7.7-8.1 (n = 2, type series).

Differential diagnosis.

Endothyrella babbagei and Endothyrella inexpectata sp. n. differ from the Endothyrella oglei by the flat dorsal surface of the shell and the presence of hairs arranged in three rows on the body whorl. See also under Endothyrella serica and Table 5.

Remarks.

The information published by Gude (1914b) (major diameter 27, minor diameter 25 mm) is wrong; it probably refers to " Chersaecia " andersoni .

Distribution.

The species is known from the type locality only (Figure 10).
