No. XXX.— ON HARRIOTTA, A NEW TYPE OF CHIM/EROIl) FISH FROM 

 THE DEEPER WATERS OF THE NORTHWESTERN ATLANTIC. 



By G. Brown Goode and Tarleton H. Bean. 



A REMARKABLE type of CliimiTeroid fisli was obtained by tlie F. S. 

 Fish Coniiiiission steamer yl //>«/ro.s,>f wliile engaged in deep-sea explora- 

 tion in the nortlnvestern Atlantie. 



Fonr specimens were taken, two of tlieiii younji', and \a irli propor- 

 tions quite unlike those of the adults. 



The limits of lange are, of course, by no means determined by the 

 capture of these isolated specimens, all of which came from between 

 latitudes north 30° 45' and 39° 44', and longitudes west 10° 30' and 

 74° 28', each specimen being from a distinct locality. The habitat of 

 the genus must then be described as western North Atlantic, 707 to 

 1,080 fathoms, oft' the coasts of Virginia, Maryland, and Delaware. 



Ill the present notice no attempt is made to discuss the relationships 

 of the new form, except to say that it is allied to Ghim'vrd, ]fi/flroJafiuf<, 

 and CaUorhi/nchus. Dr. Gill is disposed to form a subfamily of the 

 Ohimseridiie for its reception, and it is not unlikely that as a result of 

 more thorough study it may be found necessary to place it in a family 

 by itself. The descriptive notes which follow are from the advance 

 sheets of our memoir, entitled "Oceanic Ichthyology," and were pre- 

 ])ared six years ago. Fearing still further delay in the publication of 

 our book, we present them, together with tigures of both old and 

 young. 



HARRIOTTA, new uenus. 



Snout exceedingly elongate, with a cartilaginous midrib and folia- 

 ceous lateral expansions of the skin at its base. Two dorsal tins, the 

 anterior with an immense triangular spine, tinely serrated upon its 

 lateral edges. Anal tin reduced to a cutaneous fold, Longitudinal axis 

 of the tail nearly the same as that of the trunk, very elongate, with 



Procet'diuiJis of tlie IT. S. National ^Museum, Vol XVII— No. 1014.
