98 ^U.STKALIAS' SYLI.IDAK, Kl'SYLLIDAE AND At'TOIATIDAE, 



The pharynx extends tu the 5th segment, the pro\eutiiculus to the 9th. 



There are two advaiu-eil embryos, one in the 14th ami the other in the loth 

 segment. In the l'2th and 13th segments there is a single ovum on either side. 



Hitherto, as already stated, Hyllis viiipara Ivrohn has been the only vivi- 

 parous Syllid known.* From that species the jiresent form differs in the b.den- 

 tate fharaeter of the compound setae, as well as in the piesenee of frc>ntal eyes 

 and the greater lengfh of the dorsal cirri. 



Though it seems probable that .s'. partiirieiis is hermaphrouite, and that te.stes 

 are present in most of the segments, the specimen does not afford conclusive evi- 

 dence of this.

The species of iSyllis which Augener described under the name of S. 

 kinbergiana Haswell, while expressing some doubts as to the correctness of the 

 determination, is not very rare in Port Jackson, and. as it appears to be unnamed, 

 I have given it the above name. Augener's -wrong' determination is doubtless 

 partly due to my having given insufficient data; but theii- are at least two points 

 given in my original account which are entirely inconi])atible with Augener's eou- 

 elusiou — viz the very indistinctl.v articulated cirri and the transverse intraseg- 

 mental lines. Augener's description is verj' ade(]uatc. juid I will merely add the 

 following brief notes : — 



There are frecjueutly no markings, but sometimes theie is a pair of grey 

 transverse lines on the doreal surface of each segment in the anterior region. 

 Frontal eyes are present in most if not all cases, but they are sometimes repre- 

 sented by minute dots which may not be symmetrically placed. 



The ordinary compound setae resemble those of ^■. variegata in shape, but the 

 fringe of processes along the cutting edge of the fals is less developed. These 

 are the only compound setae in the posterior region. But in the anterior and 

 middle regions the two most dorsally placed in each parapodium (Plate xi., fig. 

 20) have the appendage relatively long and narrow — longer and narrower than 

 is represented in Augenei-'s fig. 22a. The obscurely bidentate simple setae of 

 the posterior region which are similar to those of 6'. variegata, may extend for- 

 wards as far as about the 20th segment from the anterior end. The acicula (figs. 

 21 and 22) are one to four; when there are two, the more anterior (fig. 21) is 

 very slightly bent fonvard at the end, with an oblique terminal (posterior) face 

 which is slightly concave: the more posterior (fig. 22) nearly symmetrically point- 

 ed. When only one aeiculum is present it is of the former typo: when there are 

 three or four, two or three are of the latter.
