the tentacular cirri. The scales (PI. XXVII, fig. 2) have a rounded trapezoidal shape, with a 

 sinuated external border, the scar of attachment lying in the centre-, they are translucent, 

 whereas a broad, semilunar, brown-red spot, consisting of large polygonal cells, occurs on their 

 internal half. A typical foot (15"^) consists of a large, cylindrical neuropodium, provided with 

 a rounded anterior and posterior lip ; the first-named is somewhat narrower than the last one 

 (PI. XXVTI, fig. 3). Between them a fascicle of setae emerges, that consists of a long, smooth 

 shaft and a short, knife-shaped appendix, the internal cavity of which appears to be divided 

 into two compartments by a transverse septum (PI. XXVII, fig. 4 a); however in the dorsal 

 and ventral part of the fascicle some of the setae have a cylindrical appendix, with an obtuse, 

 club-shaped end, whereas their shaft bears a couple of denticulated rows near its distal extre- 

 mity (PI. XXVII, fig. j^ó). In the anterior segments (2"'', 3'''' and 4''^) this appendix of the setae 

 is longer and more slender ; even in the dorsal and ventral part of the fascicle it is curved, 

 sickle-shaped, resembling the neuropodial bristles of the 2'"' parapodium of Psaiuniolycc jïava, 

 whereas 5 or 6 denticulated rows occur at the distal end of their shaft (PI. XXVII, fig. 5). 

 No stylodes are present, but some cylindrical papillae, as \n Psammolyce, occur ^Xongthehord&'c 

 of the foot. Especially in the third segment they are rather numerous. The notopodium of the 

 foot is small, papilliform and shows a fascicle of fine, capillary setae, provided with spirally 

 arranged whorls ; on its dorsum there occurs a single cushion-shaped ctenidium. A slender 

 ventral cirrus, showing a constriction at a short distance from its end, does not reach to the 

 extremity of the foot. In the anterior segments the ventral cirrus is longer and more slender, 

 extending to or beyoncl the distal end of the foot. A smal!, triangular, branchial appendix is 

 at first visible on the 3'''^ segment. 



I do not hesitate to propose a new genus for this worm ; for it cannot be ranged among 

 Psainmolyce^ that is characterized by the presence of cheliform bristles, a long dorsal cirrus 

 on the 3"^ segment and by the absence of ctenidia, nor among Lcanira, that possesses pecti- 

 nate-canaliculate setae and stylodes. 



Genus Psammolyce Kinberg'). 



Prostomium with a single median antenna (tentacle) ; lateral antennae fused with the first 

 parapodia. Four eyes. A dorsal cirrus on the third segment. Elytra and median part of the 

 back covered with papillae, adapted for the retention of small particles of the bottom. Neither 

 ctenidia nor stylodes on the parapodia. Notopodial bristles simple, capillary. with denticulated 

 whórls ; neuropodial setae compound, with a simple cheliform appendix. Papillae of the proboscis "/^j.
