This is a rare but well-known species about our shores, 
and is reported by Chun from the Antarctic. The present 
record of its distribution, occurring at stations 1, 5, 7, 8, 
12, 17, Wyse collection, is an addition.

This species occurred in the Wyse collection, stations 
15 and 18, from the Indian Ocean and the Bay of Bengal. 
Its reported range has hitherto been confined to the 
Pacific Ocean.

I found this species, twice in the Wyse collection, from 
stations 1 and 5, both in the Southern Indian Ocean. 
Its hitherto recorded range has been the Atlantic and 
Pacific Oceans.

This is a very widely distributed species, having been 
recorded from 65° N. to 26° 8. With the exception of 
stations 2 and 4, it was fairly abundant at all the Wyse 
Indian Ocean stations, and up the Bay of Bengal. Its 
occurrence at only one of the Herdman stations (No. 11) 
probably arises from its preference for the open ocean 
rather than near land. It is easily recognisable by its 
double toothed rostrum.
