286 A MOT^OGRAPH OF THE AUSTRALIAN APHRODITEA, 



are very long. The parapodia are undivided and there are no 

 dorsal setce. The ventral setee are on a type similar to that 

 presented by those of Thormora argus, but near the apex there is 

 a small tooth which has rather the appearance of a step than of a 

 prominent tooth. The elj^tra are delicate, not fringed, ornamented 

 with a band of very minute processes near the outer border. 



Griffiths' Point, Western Port. 



This species comes near L. striatus, but is distinguished among 

 other points by the form of the ventral setae, which in the latter 

 species are strongly bidentate. 



Lepidonotus seololepis, sp. n. (PI. IX., figs. 3 — 5.) 



There are 25 setiferous segments, with elytra on the ord, 4th, 

 6th, 8th and every alternate segment. The praestomial tentacles 

 are slender, the median nearly twice as long as the lateral ; like 

 the other tentacles and the dorsal cirri, they have a slight swell- 

 ing near the extremity followed by a slender tapering portion. 

 The inner peristomial tentacles are longer than the outer, shorter 

 than the mesial, but longer than the lateral praestomial tentacles, 

 smooth, cylindrical. The outer peristomial tentacles are shorter 

 and more slender than the internal one. The ventral cirri are 

 short and conical, the ventral tubercles conspicuous. The anal 

 cirri are longer than the praestomial tentacles. The parapodia 

 are divided, the neuropodium being much larger than the noto- 

 podium. The ventral setae are about 15-20 in number, xoVoth 

 of an inch in breadth and iroth in length, and are of a type similar 

 to that represented by those of Thormora argus ; the apex is 

 curved and subacute, and the lateral spines are five or six in 

 number in each row. The dorsal setae are simple and extremely 

 slender, straight, with the exception of a slight bend near the 

 apex — the thickness being slightly increased at the bend. The 

 elytra are delicate, fringed, and marked with numerous subcircular 

 or polygonal figures. The elytra and the dorsal surface below
