REPORT ON L.M.B.C. NEMERTINES.

correct, that the name is there used with the connotation 

 it bears in M'Intosh's Monograph, it is possible that the 

 Nemertine so referred to is identical with that recorded 

 in the present Report as Garinella aragoi, Joubin. 



None of the parasitic species has yet been obtained in 

 the district ; no particular search was made for them by 

 myself beyond examining a few specimens of Galathea. 

 Malacobdella will probably be found ; I had not, however, 

 an opportunity of obtaining that curious Nemertine, as 

 no living specimens of Gyprina islandica were dredged 

 during my visit. 



Two cases of abnormality in the number of marginal 

 stylet sacs in the proboscis may be conveniently mentioned 

 here. A specimen of Tetrastemma candidum (of the deeper 

 water variety with white patch on head and dorsal white 

 line) was observed having three marginal sacs, while a 

 brownish yellow example of Tetrastemma dor sale had four 

 marginal stylet sacs, two on each side. 



Before proceeding to deal with certain of the species in 

 detail it may be useful to give a complete list of the 

 Nemertines hitherto observed in the district.
