median dorsal line in the intersegmental grooves. The specimens from North Ubian show purple 

 spots. In the specimen from Ambon the head was withdrawn and concealed below a collar, 

 so nothing could be said about the position of the eyes ; in that from Banda and Saikis Besar 

 however a single pair of large eyes is visible, not far from the anterior margin of the head, 

 whereas the posterior pair of smaller ones is concealed below the lateral margin. The elytra 

 bear along their border small keeled tubercles, that towards the centre acquire a conical shape, 

 whereas some large spines occur around the scar of attachment. That Thorni. trissochaeta 

 (Gr.) should be identical with Th. yukesii Baird, as asserted by Augener^), I cannot accept, 

 without having seen the typical specimens; for the elytra are described by Grube "margine 

 laevi" and by Baird "ciliated on the external margin". This species shows a very 

 wide geographical distribution, for it is mentioned by Grube from the Red Sea, Samoa, the 

 \'iti Isles and the Philippines, while it was met with by Willey in the neighbourhood of Ceylon, 

 by PoTTS in the Indian Ocean (Zanzibar, Saya de Malha banks etc.) and by Marenzeller in 

 the vicinity of Eno-sima. 



Genus Paralepidonotus Horst. 

 Horst, Zool. Mededeel. R. Museum Nat. Historie, Leiden, vol. I, 191 5, p. 8. 



This new genus differs from Lepidonotus by a larger number of segments (38), by the 

 presence of 15 pairs of elytra situated on segments 2, 4, 5, 7.... 23, 26, 29 and 32 and 

 a much stronger fascicle of notopodial setae. 



As proved by Gravier Polynoë ampullifera Gr. "), P . boholensis Gr. ^) as well as P. pleiolepis 

 Mar.*) agree by the situation of their lateral antennae with Lepidonohis and it was a mistake 

 of Grube to range the two first-named species in the group, "with submarginal tentacles" ^) ; 

 however they possess 1 5 in stead of 1 2 pairs of elytra and Gravier therefore proposed to 

 divide the genus Lepidonotus in two sections. However in my opinion it is preferable to unite 

 these species in a new genus, because they have also the notopodial fascicle much stronger 

 developed than in Lepidonohis.

This species, characterised by the large, globular tubercles of its elytra, was first 

 mentioned by Grube from the Philippines ; afterwards it was met with in the Red Sea by
