Oneirodes carlsbergi (Regan and Trewavas 1932) 



Material.— L ACM 36068-2, 19 mm, stn 25. 



Oneirodes carlsbergi is known from the western 

 tropical Atlantic and Pacific Oceans, and from a 

 single record in the Indo-West Pacific region at 

 about lat. 17° N, long. 120° E (Pietsch 1974a, fig. 

 107). An additional specimen, collected by the 

 Alpha Helix from the Banda Sea, is the second 

 known record from this part of the world. 



Oneirodes cristatus (Regan and Trewavas 

 1932), Figure 2 



Oneirodes cristatus is known only from the type 

 material (3 females, 20-165 mm SL) collected by 

 the Dana in the Banda and Celebes Seas (Pietsch 

 1974a).
