 Lagisca, Scalisetosus and Polyno'c, were too incomialete for a satisfactory recognition. 



However it was often no easy task to decide, to what genus some species does be- 

 long, tbr every one, who has been occupied with the study of this group, will agree with 

 Johnston's assertion, that "the classification of the Polynoids is in a most unsatisfactory state, 

 and much in need of thorough revision. The great multiplication of genera, nearly all of them 

 founded upon variable, non-essential, or even accidental characters, and none of them clearly 

 and fully defined, has been a serious drawback to the study of these interesting forms" ^). Also 

 Darboux in his elaborate paper "Recherches sur les Aphroditiens"-) has not succeeded in giving 

 a clear definition of the different genera and it is not unusual to see the same species ranged 

 by different authors in six different genera. Though I fully agree with Aügener') about the 

 desirabilit)- to cancel some of the old genera f. i. Eiicrante, Eunoa, Eupolyndc, Evaryic, Lac- 

 nilla, Nychia and Parnicnis and to unite them with the genus Harviotho'c, I feel justified to 

 propose three new ones viz. : Paralepidoiiotus, Parahalosydna and Weöeria ; 1 cannot follow 

 Johnston's e.xample to cancel nearly all the genera and I prefer in accordance with Grube (and 

 Ehlers) to maintain two large groups : 



1. Lepidonotidae : the lateral frontal lobes of the prostomium prolonged to form the basal 

 joint of the paired antennae. 

 11. Harmothoidac : the lateral frontal lobes of the prostomium produced into two acuminate 

 or rounded peaks, beneath which the paired antennae arise. 



Though the greater part of Pohnoïnae are inhabitants of shallow water, some of them 

 were dredged at a great depth f. i. Lcpidonotus malayamis at a depth of 469 and 560 m., 

 Allmaniella arafurensis of 560 m., Halosydna óatheia of 959 m., Weöeria pust ti la ta oï -jgj^m., 

 Harmothoc benthaliana of 520 m. and Admctella longipedata of 538 m. ; however pelagic 

 ferms have not been met with, though Drieschia pclagica Mich. was collected b\- Driesch in 

 the neighbourhood of the isle of Ceylon *). 



The sub-family of Eulepidinae, as far as I know, hitherto was not met with in Mala)-an 

 waters ; a new species Enlepis malayana was dredged in two localities. 



Of the sub-family of Sigalioninac only two species were recorded from the INIalay Archi- 

 pelago viz. Sigalion amóoitiensis Gr., an incomplete specimen of which was collected by the 

 "Gazelle " in the neighbourhood of Amboina, where probably it afterwards was refound by 

 Semon [Sigalion sp. Collin) and Thalenessa gracilis Fischli, brought home from Ternate b\-
