the animal is, with the parapodes, nearly 5 mm — bristles not 
counted. Considering that only a fragment is present and that the 
specimen is in very bad condition an exhaustive description is 
not well possible, but I do not think that this faet is of mueh 
importance as I am inelined to mean that the specimen is not 
a representative for a nova species but merely a monstruosity 
of G. alba. A doser examination of the parapode proves that 
the only difference wich can be pointed out here is that in 
the nojmal G. alba the gilis are digitiform, while in the specimen

under consideration they are irregularly branched. Fig. 6 shows a 
parapode viewed from behind. The type of the Glycera alba-foot 
is easily recognizable. The two large anterior lobes are seen as 
well as the two posterior of which the ventral is short and rounded; 
the dorsal cirrus which is almost globular is situated at the base 
of the parapode, still somewhat elevated. Only the giil differs con- 
siderably being provided with several branches and irregular out- 
growths. Fig. 7 shows a fragment of another parapode with its 
gili which is divided in three branches almost equal in size, and 
one of which has a little, filiform appendix. Finally fig. 5 shows a 
part of the specimen with four parapodes, drawn at low power 
under the binocular microscope; in this figure it is plainly seen
