lids, for in them many of our genera were established, and numerous 

 species from southern Europe, closely allied to our own, were de- 

 scribed and illustrated in great detail. 



The following lists are arranged, as nearly as possible, in chrono- 

 logical order. Species when recorded for the first time, as from the 

 northeastern coast of America, are printed in italics, unless indeter- 

 minable by me. The names placed in the last column as the equiva- 

 lents of the original names, are those used by the writer in the Check- 

 list of Marine Intervebrates,'^ edition of 1879, unless otherwise indi- 

 cated. Those names that have been since changed are enclosed in 

 brackets. 



Although a considerable number of changes in the nomenclatui'e 

 of the annelids, included in the first edition of the Check-list, have 

 become necessary or desirable, and may be adopted in the second, or 

 systematic part of the present paper, I have thought it best to in- 

 troduce only some of the. more important ones, or those that relate to 

 the more common species, in the following lists, the Check-list being still 

 kept, as a convenient standard of reference, for the various synonymous 

 names that have formerly been used for those species included in it. 



The principal changes which I have here introduced in the synony- 

 mical lists are as follows : 



Cistenides to be changed to Pectinaria / Anthostotna to Scolo- 

 plos ^ Hhynchohohis dihranchiatus to become the type of the new 

 genus Euylycera, herein established (see p. 295). 



The common Phascolosoma ca^mentariuni appears to be identical 

 with P. strombi {PhascoUon strombi Theel) of Europe. 



The earliest notices of any of our annelids are to be found in the 

 conchological works of Gould and others, but such species as were 

 mentioned by them are mostly those that form more or less solid 

 tubes, and as their notes and descriptions usually refer only to these 

 tubes, it is seldom possible to identify, with any certainty, the species 

 mentioned by them. 



For greater convenience, I have also included, in the lists, the 

 small number of Gephyreans that have been recorded from our 

 coasts. The leeches are omitted.
