Vertical range. — Bouvier (1906) has recently investigated 

 the bathymetric range of this species, and has established the 

 fact that it is an abyssal free-swimming form. It does not 

 appear to occur normally on the bottom, and the specimens 

 which were found in the fine-meshed nets attached to the 

 trawl (recorded above) were most likely caught daring the 

 ascent of the net. It is difficult to say what is the maximum 

 depth to which the species penetrates, but according to Bou- 

 vier 's account adults seem to be more frequently taken below 

 than above 1,000 metres (about 550 fathoms). 



Larval and immature forms occur at. less considerable 

 depths, sometimes not far from the surface ; it appears that
