Hub. Dillon's Bay, Erromanga, New Hebrides (coll. Brazier). 



The original or type specimens were collected at the same place 

 by my late friend Mr. John Macgillivray ; and during my visit to 

 Erromanga, six years ago, I found it plentiful under decayed leaves 

 in very damp places near the sea, and never upon any other island 

 in the New Hebrides. The late Mr. Cuming was in error when he 

 sent it to Dr. Pfeiffer with the locality " Solomon Islands." I have 

 been through almost every island in the Solomons, and have not 

 met with any of the genus Cyclotus.

Hah. Aneiteum Island, New Hebrides : found inland in ravines 

 under wood (coll. Brazier). 



When Dr. Pfeiffer described this species, he gave the correct 

 locality, and when he brought out his secoud part of • Monographia 

 Pneumonopomorum ' he also gave it correctly, and at the same time 

 a locality of his own, New Georgia, one of the Solomon Islands. 

 It is impossible to find this species at any island in the Solomons. In 

 the third part of the ' Monographia ' he only gives " Nov. Hebrid. ;" 

 but it is only found on one island of the group, and not on all, as 

 the term New Hebrides would imply.
