The present paper deals with a collection made by Mr. Lechmere Guppy, Junr., who has followed out a suggestion made by Mr. Boulenger to such good purpose that he has sent to the British Museum a series of well-preserved specimens representing thirty-five species, including all but three of those which have previously been described from the island.
