figs. 2, 2a and b) and afterwards by Mc Intosh (Brit. Annelids, (PI. XXXVI, 

 fig. 9). In my opinion these short dorsal bristles furnish us a good 

 criterion to distinguish the different species of Hermione from each other, 

 though of course also the other characters, viz. the length of the tentacle 

 etc. might not be neglected. The statement of Fischli and Collin that 

 Herm. hystrix should be found in the neighbourhood of Ternate and 

 Amboina appears to me rather dubious. 



Hermione mohiccana n. sp. 



Siboga-expedition, Stat. 131, anchorage of Beo, Talaut-islands ; Stat. 138, 

 anchorage on the east coast of Kajoa-island; Stat. 220, anchorage off Pasir 

 Pandjang, west-coast of Binongka. 



' The largest specimen has a length of 20 mm.; its breadth (without 

 bristles) is 9 mm., whereas the number of segments amounts to 32. The 

 body has an oblong-ellipsoidal shape, with the broadest segments in the 

 median area, whereas in Herm. hystrix the segments over a large part 

 of the body have the same breadth. All bristles are yellow, only the 

 glochideal setae are darker coloured at their base and distal extremity; 

 they are directed towards the median dorsal line, whereas in Herm. hystrix, 

 and -malleata these setae are conspicuously brown-coloured and flanking 

 the lateral sides of the body. The glochideal bristles have a long, pointed 

 spear-head and two recurved fangs at one side and three at the opposite, 

 the inferior of them being the largest, about twice as long as the superior 

 ones; the distal part of their shaft is smooth, whereas the inferior part 

 is covered with small tubercles. The short dorsal bristles of the elytral 

 segments are slightly curved, covered with minute tubercles and provided 

 with a smooth, translucent tip, quite differing from those in Herm. hystrix. 

 The tip usually is surrounded by a cap of fine threads, that appear to 

 emerge from it. The bifurcated ventral setae are provided with a small 

 accessory tooth above the large spur. The head is rounded, nearly as 

 long as broad, with two large oval eyë-peduncles on its frontal margin, 

 each provided with a large black spot; between them a short tentacle 

 arises, consisting of a conical tuberculate basal part, a median joint nearly 

 twice as long as the preceding and a short, clavate, distal part. 



Hermione parva n. sp. 



Siboga-expedition, Stat. 60, Haingsisi, Samau-island ; Stat. 65ft, north 

 off Tana Djampea. 



At the above-named Stations a small Hermione was caught, that cannot 

 be identified with the preceding species. The largest specimen measures 

 18 mm. in length. In the specimen from Haingsisi the dorsal bristles are
