of the margin is "beset with rather long filiform papillae, that also are found on their upper 

 surface. In the segments, that are situated more posteriorly, the anterior border of the elytra is 

 straio-hter, whereas their median part is lobe-like elongated and a great number of papillae 

 are found on the external part of their surface. 



/'.S-. Kinbergi Hans., also found in the neighbourhood of Rio Janeiro, that I had the 

 opportunity to examine, is quite a different species, allied to Ps. arenosa with regard to the 

 appearance of the bristles, of the dorsal cirrus of the third segment etc. ; unfortunately the 

 fio-ures. eiven bv Hansen, are not very accurate.

This worm belongs to those Psainvio/yce-s^i&des {Vike Ps. /ijicusis^) and Ps. occïdeuia/is^), 

 that have the anterior extremity of the body snout-like elongated, on account of the extra- 

 ordinary length of the first pair of elytra (PI. XXVII, fig. 11). The species appears to be very 

 brittle, for only the anterior portion of the body of the various specimens is preserved ; per- 

 haps the posterior body-region is buried into the bottom of the sea. The entire dorsum is 

 covered with coarse grains of sand, Vith the shells of foraminifera, with spicules of Alcyonaria 

 and .Sponges and with pieces of the shells of Echinoidea and Molluscs. 



The ventral side of the body is hairy, on account of the presence of long, slender pa- 

 pillae, especially in the vicinity of the mouth, that is almost entirely hidden by them. The 

 venter as well as the bristles are of an ochreous hue. The first pair of elytra have an elongated, 

 elliptical shape, with a concave, wing-like lobe at the anterior part of their median border ; 

 this lobe excepted the whole margin is beset with filiform papillae. The right elytron of the first pair 

 somewhat overlaps the left one, but they diverge with their anterior part, thus making the ten- 

 tacle and the bristles of the buccal segment visible. The other scales are semi-circular, with 

 a straight anterior border and a conical lobe at their internal angle ; their posterior margin is 

 beset with filiform papillae, that are longest at the external side, where they are separated 

 in 3 or 4 groups by small cup-shaped papillae. The cephalic lobe bears a pair of distinct black 

 eyes on its dorsal side, almost hidden under the nuchal fold and another pair of larger ones 

 beneath it. The tentacle has a distal part, about twice as long as the basal one ; its tip is 

 swoUen and extends nearly lill the extremity of the bristles of the first segment and the ten- 

 tacular cirri. The basal part is furnished on each side with a small semilunar ring. The palps
