NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 115 



These specimens agree well with those so designated from Coiba 

 Island, Panama, by Monro (1933, p. 63), but differ in some respects 

 from the original, taken at Bare Island, New Zealand (Ehlers, 1905, p. 

 288). Ehlers' original description was corrected on some points and en- 

 larged by Augener (1924, p. 402), who re-examined the type material. 

 In the latter, composite hooks have a much heavier secondary tooth, the 

 subacicular hooks are more distinctly bidentate and curved. Further- 

 more, Augener described them as "hellfarbig," and the secondary tooth 

 as larger and longer than the distalmost. These differences may have 

 specific significance. 



Eunice valens (Chamberlin) (1919, p. 257) from the eastern Pacific 

 agrees more nearly with the specimens here questionably referred to E. 

 tridentata, from New Zealand. In E. valens the prostomial antennae are 

 weakly articulate or nearly smooth; composite hooks have a rudimentary 

 secondary tooth; branchiae are present from the third setiger, with at 

 most 10-12 filaments, and they end at about parapodia 80-85; the total 

 number of segments is 180 or over. However, maxilla II is said to have 

 6 or 8 teeth, whereas in E. tridentata it is said to have only 4 or 3 teeth. 

 Since the number of teeth varies within limits, this difference may not be 

 significant. The collections listed above are referred questionably to E. 

 tridentata (sensu Ehlers and Augener) but agree with those so desig- 

 nated by Monro (1933) and perhaps with E. valens (Chamberlin). 



Distribution. — Panama, north to Lower California, in a few fms.
