hartman: polychaetous annelids 219 



14 anterior segments of which 7 have modified dorsal cirri, has about 50 

 epitokal segments and is nearly as long. Color is lacking except for the 

 reddish-brown eyes and a dark transverse band across the dorsum of the 

 second parapodial segment. 



Jaws are translucent, dark amber in color, with 5 teeth on the cutting 

 edge. Paragnaths are present as follows: area I with none; area II with 

 a crescent of 2 or 3 rows of paragnaths ; area III with a broad patch ; area 

 IV with a triangular patch ; areas V to VIII with none. 



The postepitokal parapodia have middle and ventral lobes about 

 equally long, but the dorsal lobe is longer (pi. 35, fig. 48). Homogomph 

 falcigerous setae are absent. The specimen from 702-37 is an anterior 

 fragment of 17 setigerous segments and a regenerating posterior end. The 

 anterior third of each segment is crossed by a dark band dorsally. 



These specimens are referred to C. costae largely because the posterior 

 parapodia have a preacicular notopodial lobe (pi. 35, fig. 48). 



Distribution. — Mediterranean; Indo-Pacific; Madagascar; Philip- 

 pines; Ecuador; Gulf of California. Intertidal, to 18 fms. 



Genus NEANTHES Kinberg 



Neanthes differs from Nereis mainly in that the preacicular notopo- 

 dial lobe elongates, and notopodia have spinigerous setae only. Conical 

 paragnaths are usually present on all areas. 



It is of interest that no representatives of this genus are present in the 

 collections of the Hancock Pacific Expeditions. Two species (see below) 

 are in the collections of The University of Southern California. These 

 have heretofore been reported from California (Hartman, 1938, p. 80). 

 Both are fairly common in littoral zones. They are separable as follows : 



Posterior notopodial lobe elongate, the dorsal cirrus inserted near its 

 distal end; often estuarine . N. succinea (Frey and Leuckart) 



Posterior notopodial lobe broadly foliaceous, the dorsal cirrus insert- 

 ed near the middle of its dorsal convex edge; marine
