The present occurrence serves to materially extend the recorded 

 horizontal range of H. Rheinhardti, but, unfortunately, adds nothing to 

 our knowledge of its normal habitat. 



The species is only known from isolated specimens taken in coastal 

 waters or cast up upon the shore at widely scattered localities in the 

 North-East Atlantic. It is inconceivable that our records could be so 

 scanty were a fish of so striking and singular an appearance a normal 

 denizen of shallow water in the East Atlantic. 



The well-defined Pediculate family of Ceratiidce, to which Himan- 

 tolophus belongs, and of which it appears to comprise by far the 

 largest species at present known, had until lately, by the general con- 

 sensus of ichthyologists, been regarded, at any rate when adult, as 

 confined to very deep water, and its members have been termed by 

 Grunther and other authors following him ' Bathybial sea-devils.' 



As already stated, Liitken obtained very small specimens of some 

 Ceratiids from the surface of the South Atlantic, and more recently 

 Dr. Brauer (1902) has stated that the Valdivia expedition ' has shown 

 with certainty in the case of all Ceratiidce taken that they do not live 

 on the bottom of the sea, as was hitherto almost generally assumed, 



1 These measurements will be found not to correspond with the dimensions 

 shown in the figure, in which the loose skin is represented in the moderately 

 distended condition apparently normal in life.
