The parapodial change from anterior to posterior regions occurs at 

 about segment 39-41. Chevrons of the proboscis number 7 to 11 pieces 

 on a side. Micrognaths number about 4 larger pieces in the ventral 

 arc and 2 or 3 smaller pieces in the dorsal arc. 



The proboscidial organs (figs. 7, 8) are of a single kind but vary 

 somewhat in size. They resemble those of G. brunnea (pi. 1, figs. 5, 6) 

 but the surrounding flange is less flaring and the organs are attached 

 differently so that they usually appear cordate instead of subcircular, 

 when seen from the front. Furthermore, although the flange is cres- 

 centic, it is usually directed downward so that the base of attachment is 

 seen from the front. As in G. brunnea, the pore of the central mass is 

 directed away from the gnathal end. The pore leads to a canal and 

 large cell, and on its outer side to a depressed groove that has no con- 

 nection with the inner canal. 



Distribution. — G. maculata is the most widely distributed of all 

 known species of the genus ; it is recorded from western Europe, north- 

 eastern North America, Alaska and northern Japan (Okuda, 1939); 

 Wesenburg-Lund (1949) has recorded it from the Gulf of Iran.
