REPORT on the VERMES of the L. M. B. C. DISTRICT.

Introduction. 



The Vermes collected by the Liverpool Marine Biology 

 Committee during the summer of 1885 form a fairly 

 representative series of types of all the main groups. The 

 Chaetopoda, are especially well represented, numbering no 

 less than thirty-seven out of the total number of forty-two 

 species collected. Some of these are particularly interesting, 

 not only as having been found here now for the first time, 

 but also as having been observed only very rarely around our 

 coast. Most of the Tubicolous Annelides are, however, com- 

 mon forms. 



The classification I have adopted is that of Claus ; * in 

 the nomenclature of species I have followed Mcintosh in his 

 Monographs t on the various groups of British Vermes and 

 his " Challenger " Report, I desire specially to acknowledge 

 my indebtedness to Dr, Mcintosh, F.R.S., for the uniform 

 kindness with which he has answered many questions with 

 regard to the identification of species with which I had 

 difficulty. 



Of the more important additions to our Fauna, as 

 recorded by Byerley, the following seem worthy of special 

 mention : — Carinella linearis among the Nemertea ; Lagisca 

 propinqua, Harmothoe haliceti, Malmgrenia castanea, Iphione 

 imiricata, Hermadion assimile, Sthenelais zetlandica, Spio-
