In some respects my specimens agree better wltl\ Gruhea dolich- 

 opoda Marexzeller (1. c, p. 26) than with G. tenuieirrata Clpd. 

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

 pliaryngeal tooth. According to Claparede's figure, the sette end 

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

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

 being very small, and reqniring 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) setae existed on nineteen segn:ients. The eggs 

 and young in different stages of development agree very closely 

 with those described by Claparede as belonging to Syllis imlligera 

 'Kv.onn {Sy Hides pidligera Cup^.)^ Glanures, etc., p. 81, pi. vi, fig. 6. 



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

Male. 



Capillary setre begin on the eleventh setigeroufe segment, and are 

 found on all following segments except the last 2— i. They are 

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



The body from the eleventh, or sometimes from the sixth, ses'- 

 ment, is pure white and much swollen. 



Femdle. 



Capillary setne 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 

 now satisfied that our specimens belong to Gruhea doUchopoda Marenzeller. Lauger- 

 haus, however, identifies this with Gruhea clavata Clpd. {ZeitschriftfiXr Wissemcha/t- 

 liche Zoologie, p. 564. 1879.)
