6. SYNOPSIS OF THE FAUNAL CATALOGUE. 



A table has been prepared showing the total number of families, genera, and species 

 comprised in our annotated list, grouped according to the larger divisions of the animal 

 kingdom; likewise the number which have been recorded during our dredging operations 

 and the number of those encountered which had not previously been listed for local 

 waters. In this table species have been entered as doubtful, either because the determi- 

 nation of the species was made with doubt, or because of uncertainty whether the 

 specimens taken really came from within the region here considered.** 



In the "undetermined" column are included species which have been referred to 

 a genus but not to a species, provided only that no determined member of the satn^ 

 genus has also been Hsted with which the species in question may be identical. 



Species have been listed as "taken by dredge" which were recorded either from the 

 regular dredging stations of the survey or from any of our supplementary stations, 

 numbered or unnumbered. 



Species have been listed as "added to fauna of region" when it is believed that their 

 local occurrence was recorded for the first time, either as a result of the sur\xy dredging 

 or of the other collecting operations which were carried on during these same years by 

 members of the laboratory staff or by investigators who have cooperated in the work. 

 In many cases, it is true, these additions to our local fauna have been announced in 

 other publications, but their inclusion here seems none the less justifiable.

a Certain species only recorded from beyond the 20-tathom line, and thus perhaps somewhat extralimital. are also here listed 

 li The species added by von Graff (1911) have been included in this table. Von Graff's famiUes are likewise included in 



the computation.
