with minute tubercles and terminates in a short hook. The ventral bristles 

 are nearly straight, beset over one side of the short distal region with 

 villous appendages; in some of the bristles that villous coating projects 

 beyond the apex, as in Aphrod. intermedia (Challenger Annelida, PL YIa, 

 fig. 1). However in young specimens these bristles have a quite different 

 appearance; their tip lack the villous beard and are shaped like a pen, 

 provided with three or four indistinct teeth. They are situated in the 

 neuropodium as usually in three rows : two stout ones, dark brown coloured 

 dorsally, 5 shorter bristles in a median series and 8 ones ventrally. The 

 head is heart-shaped, with a small knob-like tentacle in the middle of the 

 anterior region, as in Aphrod. acuminata from Florida; on each side of it 

 there occurs a prominent area, on which two minute black spots are 

 situated in a transverse series. The palps are rather long, with an acute 

 extremity; they show a constriction in their basal region. The facial 

 tubercle is oblong-conical, beset with papillae. The specimen has a length 

 of 27 mm., whereas its breadth in the middle of the body is 14 mm. 

 (without bristles); the number of its segments is about 30. 



Aphroditella limosa n. sp. 



Siboga-expedition, Stat. 178, north off Ceram; depth 835 M. 



The body is oval, long 27 mm., broad 18 mm.; it consists of about 

 30 segments. The whole dorsum is covered with mud, containing Fora- 

 minifera-shells, Annelid tubes etc. hiding all the parts of the animal except 

 the ventral bristles and the palps. The ventral side, attenuated posteriorly, 

 is densely covered with small papillae. The ventral bristles have their 

 distal part faintly S-like curved, terminating in an acute tip, and provided 

 along the underside with a villous beard; as usually they are arranged 

 in three rows. The dorsal bristles are represented by a fascicle of fine, 

 smooth, faintly curved setae, that lie totally embedded in the dorsal felt 

 and terminate in a vitreous, hook-shaped tip, directed towards the 

 median dorsal line. The head is oval with its broadest part directed ante- 

 riorly; its possesses two rather large, globular eye-peduncles, without 

 pigment. The tentacle is short and very slender, not quite as long as the 

 head and a narrow, keel-shaped, facial tubercle, covered with papillae 

 and somewhat longer than the head, lies enclosed between the base of 

 the palps. The palps are rather long, slender and tapering distally, beset 

 with spinous papillae. This species somewhat resembles Aphrod. obtecta Ehl. 

 from the coast of Florida.

Our knowledge of the Indo-pacific species of the genus Hermione is
