Notes
A lectotype was designated by Johnston in 1948, that specimen resides in the MCZ (175577). Johnston, 1971 states that there is a paralectotype lot at the BMNH (71.7.11.1). In Hanley's original description he states that the type(s) are in his collection. Johnson, 1948 states that 'after Hanley's death the collection went 'to Crewe Hanley', who gave some types to the British Museum; the rest were sold to Harvey of Houndsditch, who held them in 1906. Fortunately, Robert F. Geale, an English shell dealer, ... sent one of the types to John G. Anthony.' This was the specimen designated as the lectotype. As the Leeds specimen is from Hanley, and the general type locality, we cannot discount that it may have been part of the original type series but it is not certain. Leeds specimen has a Hanley label, no type written, and it is from the general type locality of Borneo. This species is mentioned in Hanley's handwritten catalogue but there is no mention of type. The specimen does not seem to have been examined by Kabat as part of their work on Hanley's new names, it is not referred to in their paper. A more modern label states that this is a paralectotype.
