The palps are large, tapering distally and covered with papillae. Two large eyes, situated next 

 to each other, occur on the lateral sides of the head. Both tentacular cirri are nearly of the 

 same length and extend as far as the palpi. The parapodia are very slender ; in the posterior 

 region their length is equal to the breadth of the body, in the anterior segments thêy mea- 

 sure two thirds of its breadth. There are 26 pairs of elytra (PI. XVI, fig. 2), as in other Lepi- 

 dasthenia-s^&cx&s situated on segments 2, 4, 5, 7, 9. ..23, 26, 29.. .65; they have the shape 

 of greyish, minute, oval buds, smooth, not quite so high as broad and fixed at their median 

 side to a long elytrophore, which is provided with annular groeves and does not reach beyond 

 the distal end of the neuropodium. About the internal structure of these organs I could observe, 

 that like in other elytra there^ is an epidermis-layer of polygonal cells, ending at their base in 

 slender fibres, forming a dense network in the centre of the organ ; the presence of a nerve 

 could not be stated with certainty, but they contain a great number of dark, yellowish, glan- 

 dular (?) cells. The dorsal cirri (PI. XVI, fig. 3), also inserted upon long, annulated cirrophores, 

 are rather short and do not exceed the elytra much in length except on the anterior seg- 

 ments. The notopodial fascicle is absent and only represented by the acicula ; the neuropodial 

 bristles are faintly curved in their distal part and show a short subterminal dilatation with a 

 small number of transverse spinous rows. The inferior setae (PI. XVI, fig. 4 d) of this fascicle 

 have a .simple undivided apex ; however some of the dorsal ones (PI. XVI, fig. :\.a) have a 

 bifurcated tip, the main point being elongated in a long, slender, acute limb, whereas the other 

 limb measures about a third of its length. 



A remarquable species {Lepidast. ))iichaelseni) was described by Augexer from Cock- 

 burn Sound (Southwest- Australia), characterised by a papillate nuchal collar^).

At the above-named Station the anterior fragment of a rather large worm was dredged, 

 consisting of 38 segments; it is about 35 mm. long, whereas its breadth measures 9 mm. 

 (with bristles). In my opinion the specimen cannot be identified with one of the described spe- 

 cies, but on account of the fragmentary stade of the worm I hesitate to propose a new name 

 for it. Its head much resembles that of Lepidast. microlepis ; the antennae are rather short, nearly 

 of the same length, the palps however are much stouter, more than twice as long as the 

 median antenna. There are two pairs of small indistinct eyes. The scales, except the first pair 

 of them that is large, are small, not entirely covering the parapodia; they are roundish, pro- 

 vided with some black spots and a black edge. In the neuropodial fascicle the uppermost setae 

 (PI. XIX, fig. 10) have an elongated, pointed tip, much longer than the spur, like as in 

 Lepidast. sibogae ; in the anterior segments the inferior setae also have a pointed tip, but 

 without a spur. The dorsal cirrus, dotted with black, reaches as far as the edge of the para- 

 podium ; the ventral cirrus is much shorter, about a third of its length.
