Annelida of the Bernwidas. 615 



Haplosyllis palpata, sp. no v. 



An elongated, slender, somewhat larger species, with large palpi 

 and longer dorsal cirri and setae than those of P. cephcdata. The 

 head and antennae are nearly as in the latter ; the palpi are very 

 large and thick, subovate ; the body has more numerous and more 

 distinct segments. The dorsal cirri are unequal, but the longer 

 ones, along most of the body, have about 9 or 10 rounded annuli, 

 about as long as broad, and in length are equal to about \ the diame- 

 ter of the body. The setae consist of two or three simple, strongly 

 bidentate setse, similar to those of the preceding sjDCcies, but larger 

 and loflger, and of one or two acicula, one of which has a small bent 

 tip. The oesophagus is rather long, tubular; its margin is indistinct, 

 but seems to be entire; the tooth is small. H. Setuhalensis (Mclnt.) 

 (as Syllis) resembles this species in the character of its setae. 



Trypanosyllis attenuata, sp. nov. 



Body very long and slender, composed of a large number of rather 

 elongated segments. Cirri all moderately long and strongly beaded 

 with rounded annuli. 



Setae numerous, all compound with rather long narrow blades. 



Head about as long as broad, well rounded and slightly three- 

 lobed in front and nearly truncate posteriorly. Eyes 4, small, black, 

 in trapeze, the anterior ones a little larger and situated much behind 

 the middle of the head, at about the posterior third, separated from 

 the posterior by a distance equal to about four diameters of the lat- 

 ter. Palpi large and broad, wider at base than the head, separate 

 to the base, divergent, thick at the base and incurved on the inner 

 margin, very obtuse at the end. 



Antennae and tentacle are gone ; upper tentacular cirrus long and 

 slender, composed of about 17 rounded annuli; first dorsal cirrus 

 considerably longer, with about 24 annuli. Succeeding dorsal cirri 

 are all much shorter and somewhat unequal, the longer ones being 

 about as long as the diameter of the body, and composed of 12-14 

 rounded annuli, mostly about as long as broad, or a little longer dis- 

 tally ; the shorter cirri are about f as long. Similar cirri continue 

 to the end of the body, gradually decreasing in size. 



The caudal cirri are long and slender, their length being equal to 

 the diameter of the body in its middle, composed of about 13 annuli, 

 which are mostly longer than broad. 



The setae are numerous and slender, about 10-12 compound ones 

 in the anterior fascicles, with three or four small slender acicula that 

 do not project. The blades of the upper setae are narrow and nearly
