 toward its posterior end by brown concentric lines much more easily seen on the dorsal 

 than on the ventral surface. 



My specimens of L. nasuta were taken from Tuckerstown Bay and Boat Bay, Ber-

The anterior end of the living animal (plate 8, figure 10) shows the general colora-

 patches, rather indefinite areas of pigment, one in the median line and one on either 

 side, the lateral ones being the larger. These pigment spots persist in alcohol. 



The prostomium is a blunt sugar-loaf form (plate 8, figure 10), the first two somites 

 approximately equal in length and without parapodia. This relative length of the two
