All of the collections including holotypes and paratypes are deposited 

 in the Allan Hancock Foundation of The University of Southern 

 California. 



The number of known genera of Capitellidae is 21 ; in addition, 3 are 

 newly erected herein, bringing the total to 24. Among these only 7, or 

 less than one-third, were treated in a voluminous monograph of the 

 family (Eisig, 1887, pp. 1-906), but this study was concerned with only 

 10 species in 6 genera from the Mediterranean Sea. Most of the other 

 species and genera have since been newly described and many remain 

 known only through original accounts scattered in many articles and 

 journals. Furthermore, 17 of the 24 genera are monospecific, so that the 

 total number of species for the family is still small (only about 49 species 

 are generally recognized). One genus, Eunotomastus Mcintosh (1885) 

 is too incompletely known to incorporate in the chart. 



The known genera with species and approximate distribution are 

 listed below, in alphabetical order. 

 Barantolla Southern (1921) with one species, B, sculpta Southern from 



India. 

 Branchiocapitella Fauvel (1932) with one species, B. singularis Fauvel 

 from India.
