55 



enumerated by Benson. The only other contribution is by A. A. 

 Fauvel, who recorded four species. Of Benson's records two are 

 doubtful : (r) Hehtiplerfa ><friafa, Gray, a Singapore shell, and in Dr. 

 von Martens' opinion included in the present fauna owing to an acciden- 

 tal change of label ; and (2) Plerfofrojjis fajjeina, Bens., believed by 

 the same authority to be a mistake in identification for P. osbeckei, Phil.

Extensive collections were made in this island in the sixties of last 

 century, by the then British Consul, Robert Swinhoe, and were des- 

 cribed by Henry Adams, and by Pfeiffer. Quite recently Schmacker 

 collected a number of shells, and described them in conjunction with 

 Professor Boettger ; his lamented death has deprived us of an ardent 

 field naturalist, from whom considerable additions to our knowledge 

 were expected. 



Several genera, both of Zonifidae and Helieidae are represented, 

 many showing close affinity with Chinese forms.
