- In some respects my specimens agree better with Qruhea dolieh- 

 opoda Marbnzeller (1. c, p. 26) than with G. temiicirrata Clpd. 

 This is especially the case in the form of the setse and of the 

 pharyngeal tooth. According to Claparede's figure, the setiB end 

 in a single point, and with the magnifying power used by him this 

 does seem to be the ease ; in reality they are bidentate, the teeth 

 being very small, and requiring a high power to bring them out 

 distinctly. On only two specimens was the first dorsal cirrus much 

 longer than the second. 



The anal cirri, in the only case where they were seen, were as 

 long as the dorsal cirri, and somewhat swollen at base. 



Body colorless; stomach white; intestine colorless; eyes very 

 dark reddish-brown. 



The sexual setse begin on the ninth setigerous segment. All the 

 males had lost the posterior part of the body, but on one specimen 

 the capillary (sexual) setse existed on nineteen segments. The eggs 

 and young in different stages of development agree very closely 

 with those described by Claparede as belonging to Syllis pulligera 

 li.T.oui^ {Syllides pidligeraQi.'p-D.)^ Glanures, etc., p. 81, pi. vi, fig. 6. 



Not common ; ten to fifteen feet, on shelly bottom.*

Male. 



Capillary setae begin on the eleventh setigerous segment, and are 

 found on all following segments except the last 2-4. They are 

 •delicate, longer than the width of the body, including the feet. 



The body fi'om the eleventh, or sometimes from the sixth, seg-- 

 ment, is jjure white and much swollen. 



Female. 



Capillary setae as in the males, only a little shorter. 



Eggs attached to the ventral surface by a peduncle, two to each 

 segment ; at first spherical, then becoming elongated ; purple with 

 many black specks. 



The constriction dividing the head from the body appears first ; 

 at this time the eyes are apparent, the antennae are mere buds, equal 

 in length, the palpi are not united along their outer two-thirds. 



The young, when detached from the body of the mother, have a 



* Since writing the above I have had further opportunity of studying this species. I am 

 BOW satisfied that our specimens belong to Griihea dolichopoda Mare.n'zeller. Langer- 

 haus, however, identifies this with Grubea clavata Clpd. {Zeitschri/t fur Wissenschaft' 

 iiche Zoologie, p. 564. 1879.)
