Description:                                                                   
    A survey of the Milky Way southward of the Palomar Sky Survey for the      
    identification of reflection nebulae was carried out at the Cerro Tololo   
    Inter-American Observatory in Chile.  Plates in blue light were obtained   
    at the Curtis Schmidt telescope covering a strip of plus or minus six de-  
    grees of the galactic equator.  Red sensitive plates for comparison were   
    also obtained with the same telescope covering the same area near the gal- 
    actic plane.  Observatory staff members and some students of the University
    of Toronto, Canada assisted in identifying stars imbedded in nebulosity as 
    shown by the plates.  Although this catalogue roughly compliments the Cata-
    logue of Reflection Nebulae of van den Berg (1966), the region here survey-
    ed is more narrowly confined to the galactic equator.

Note (1): Types given are I, II, I-II, or pec.  These are defined as follows:  
   I: Nebulae in which the illuminating star is embedded in the nebulosity.    
   II: The illuminating star is situated outside the nebula.                   
   I-II: This combination type was undefined in the original publication.      
   pec: Peculiar.                                                              
Note (2): Surface brightness is coded as follows:                              
     'vBr'=very bright; 'Br'=bright; 'M'=moderate; 'F'=faint; 'vF'=very faint. 
Note (3): Color types are coded:                                               
     'vB'=very blue;  'B'=blue;  'mB'=moderately blue;  'I'=intermediate;      
     'mR'=moderately red;  'R'=red;  'vR'=very red.

Note to the electronic version (by Raymond Bruton, pam99999@swbell.net and     
    Patrick Chevalley, pch@crosswinds.net):                                    
    The intended purpose of the electronic version of the BHe catalogue is for 
    use with the computer plotting of star charts.  Astronomical software,     
    (Cartes du Ciel-Sky Charts) developed by the second editor (Patrick Che-   
    valley) was used to test dataset validity.                                 
    see: <http:/www.astrosurf.org/astropc>                                     
    Any errors in the dataset should be reported to the editors.  Any gross er-
    rors in the original should likewise be reported.  As a check on errors the
    work of Herbst (1975) was consulted. When used with the northern dataset of
    van den Berg (1966) the work of Racine (1968) was likewise consulted as a  
    check for possible errors and misidentifications.  The indisriminate com-  
    parison of the present work with the work of van den Berg(1966) is not rec-
    omended.  When using the northern and southern datasets for reflection     
    nebulae together for plots of surface distribution the differences are     
    clearly evident.  This was also indicated in the original publication of   
    van den Berg and Herbst(1975).  For plots of the southern nebulae further  
    from the galactic plane than the present work a remedy was sought and in   
    part found.  The catalogue of southern dark clouds of Hartley, et al(1986),
    <VII/177> was used because of prolific notes about association with bright 
    nebulae.  Although this combination was useful the editors also used the   
    catalogue of Herbig and Bell(1988),<V/73A> for cross checks on position    
    errors.  The editors were motivated to produce the present dataset in part 
    due to the popularization of some BHe objects by Slotegraaf(1998).  Mr.    
    Slotegraaf also encouraged the production of the present dataset in private
    correspondence. This work would not have been possible without the use of  
    the NASA Astrophysics Data System maintained at Harvard College, USA., for 
    the obtaining of the original paper of van den Berg and Herbst(1975), and  
    closely related papers.  The American Astronomical Society, and the Univer-
    sity Press, Chicago, USA, are thanked for making copyrighted papers from   
    the Astronomical Journal avalaible to the NASA Astrophysics Data System and
    indirectly to the editors.
