are described by Grube "mar gin e laevi" and by Baird "ciliated on 

 the external margin". 



Paralepidonotus n. g. 



This genus differs from Lepidonotm by a larger number of segments 

 (38), by the presence of 15 pairs of elytra, situated on segment 2, 4, 5, 

 7 . . . . 23, 26, 29 and 32, and by a much stronger fascicle of notopo- 

 dial setae. 



Paralepidonotus ampulliferus (Gr.) '). 

 Siboga-expedition, Stat. 71, Makassar and surroundings. 

 Of this species, characterized by the large globular tubercles of its 

 elytra, only a single incomplete specimen was found. 



Paralepidonotus boholensis (Gr.) 2 ). 



Siboga-expedition, Stat. 33, bay of Pidjot, Lombok; Stat. 49 a , Sapeh- 

 strait; ? Stat. 138, anchorage on the east-coast of Kajoa-island ; Stat. 162, 

 west-coast of Salawatti ; Stat. 1 64, South off Salawatti ; Stat. 220, ancho- 

 rage off Pasir Pandjang, west-coast of Binongka, reef; Stat. 282, ancho- 

 rage between Noesa Besi and N. E. point of Timor ; Stat. 305, Solor-strait. 



Of this species first described by Grube from the Philippines and 

 since only met with by Fauvel among the Annelids of the Persian Gulf 3 ), the 

 Siboga-expedition collected 4 complete and 4 incomplete specimens. It can be 

 easily recognized by its conspicuously coloured elytra, that issuing from 

 the scar of attachment, are divided in four opposite areas, an exterior 

 and interior, dark, blackish, and an anterior and posterior area, pale, 

 buff-coloured. The large anterior, pale area is densely beset with small 

 tubercular papillae, that interiorly and posteriorly pass into large acute 

 spines; moreover the interior and posterior margin is provided with a 

 fringe of long cylindrical papillae, with dilated tip, that anteriorly 

 decrease in number and in length. Characteristical for this species is 

 also the semilunar lobe at the posterior ventral margin of each segment, 

 at the median side of the nephridial papilla, commencing on the 4 th segment.
