tacular cirrus. The lateral antennae are rather long, somewhat longer than the head. The palpi 

 are stout and long-, they extend about to the io*i> segment. The scales (PI. XXV, fig. 2) are 

 reniform, translucent, with the scar of attachment situated nearly in the centre, a little laterally ; 

 their surface is densely covered with minute spines, except an anterior and exterior area, that 

 are .nearly barren. Moreover there occur along the outer border some slender digitiform pa- 

 pillae. The buccal segment bears two tentacular cirri of different length, the ventral one mea- 

 surincr about a fifih of the dorsal cirrus. The second segment has a rather long and slender 

 ventral cirrus; however it does not extend beyond the distal extremity of the foot. The hr.st 

 branchial process occurs on the 5"^ parapodium. The parapodia (PI. XXV, fig. 3) are charac- 

 terized by the scarcity of stylodes; in the 19* segment f. i. the cylindrical notopodium bears 

 only two short oval stylodes at its distal extremity. lts fascicle contains a dorsal group of 

 stout whorled bristles and a ventral one of smooth capillary setae ; the neuropodium is trian- 

 crular, with a short conical stylode at its dorsal and its ventral side. The dorsal neuropodial 

 setae (PI. XXV, fig. 4) have denticulated whorls at the distal end of their shaft. The three 

 parapodial ctenidia are present, the inferior being cup-shaped.

 I specimen. 



Only the specimen, captured in Strait Makassar, is complete, measuring 80 mm. in length. 

 The elytra leave the median region of the dorsum uncovered, except in the anterior segments, 

 where they meet each other ; they are translucent, granulated, without papillae, with the scar 

 of attachment in the centre. They have a rounded rectangular shape, transversely elongated -, 

 their anterior and internal margin is somewhat concave, whereas the external border is notched 

 like in Enlcpis. The prostomium (PI. XXV, fig. 7) is rounded, about as broad as long, with 

 a pair of conspicuous eyes just on its anterior margin and another pair, provided with a lens, 

 situated more posteriorly, somewhat in front of the median region of the head. From this 

 region the median antenna (tentacle) arises, that consists of a rather long, cylindrical basal 

 part (ceratophore) and two short, subulate joints, separated from each other by a rather deep 

 constriction, quite like in Lean. hystricis, as figured by Ehlers"); in our species however the 

 distal end of the ceratophore shows a pair of oval, leaf-like ctenidia, ^?,\\\ Lean. tetragona. 

 The lateral antennae, coalesced with the buccal segment, have the same appearance as the 

 median one and consists of two joints, a broad basal and a subulate terminal one. The dorsal 

 tentacular cirrus is not quite as long as half the length of the palps ; the ventral one is very 

 short and does not extend beyond the basal joint of the dorsal one. The bristles of the buccal 

 segment nearly reach the distal end oi the dorsal tentacular cirrus.
