Depth. — Littoral, and down to 42 (? 5.5) fathoms. 



Remarks. — This species has been recorded from Peru on the strength of 

 several specimens collected by Vierau labelled " Peru " in the collection of the 

 Hamburg Museum. I have elsewhere suggested' that the "Peru" intended 

 might possibly be the island Peru in the Gilbert group. These specimens form 

 part of a very old collection, and Professor Pfeifer and Dr. Michaelsen tell me 

 that the localities as given are unreliable.
