NEPHTYS SCHMITTI, new species 



FiGTJBE 65 



Length 80 to 90 nun; width about 8 mm at widest part or tenth 

 setiger; number of segments about 100. Prostomium about twice as 

 broad as long, broadly j^entagonal (fig. 65, a), with a shallow, median 

 concavity in its anterior half. Prostomial antennae bluntly conical, 

 subequal, inserted at antero-ectal margin of prostomium. Nuchal 

 papillae near posterior margin of prostomium in line with prostomial 

 antennae (fig. 65, a). 



Proboscis proximally smooth except for longitudinal wrinkles of 

 contraction: subdistally with 22 rows of papillae, 4 to 6 in a row; 

 without median dorsal papilla. 



Figure 65. — 'Meplitiis schmitti, new species : a. Outline of prostomium in dorsal view ; 

 ft, notopodium of thirty-eighth parapodium in anterior view ; c, twenty-first parapodium 

 in anterior view (the two rami somewhat separated). 



Recurved cirri present from seventh setiger, minute at first. Dorsal 

 and recurved cirri about equal at ninth setiger. More post-eriorly 

 recurved cirri elongate and thickened ; at twelfth setiger foliaceous 

 processes arise laterally from recurved cirri and become well devel- 

 oped by fourteenth (fig. 65, c). Foliaceous lobes disappear from about 

 thirty-sixth setiger; thereafter cirri are digitate and somewhat out- 

 wardly curved (fig. 65, 6), continuing large to ninth last setiger, 

 then abruptly reduced to a minute knob and absent from last eight 

 setigers.
