8. Leanira sp. 



Stat. 311. Sapch Bay, East coast of Sumbawa. Reef. i specimen. 

 Two frafjments of a Leanir'a-s^&ÓQS, too incomplete for a satisfactory Identification. 



9. Leanira sp. 



Stat. 321. 6°5'.5 Lat. S., 11 3° 30' Long. E. Java Sea. Depth 82 M. i specimen. 

 Two fragments of a Leanira-S'p&cies, too incomplete to be duly identified. 



10. Leanira sp. 



Stat. 167. 2°35'.5 Lat. S., 131° 26.2 Long. E. West off New Guinea. Depth 95 M. i specimen. 

 A single specimen, too indifferently preserved for a satisfactory identification and description. 



Genus Euleanira Horst. 

 Horst, Zool. Mededeel. R. Museum Nat. Historie, Leiden, vol. II, 1916, p. 12. 



Prostomium with a single media n antenna (tentacle), with ctenidia at its basal joint; 

 lateral antennae fused vi^ith the first parapodia. Four eyes. Parapodia furnished with ctenidia 

 and papillae ; no dorsal cirrus on the third segment. Notopodial bristles simple, capillary, with 

 denticulated whorls; neuropodial setae compound, with a simple, knife- or sickle-shaped appendix.

At the above-named Station a small worm was dredged, belonging to the sub-family 

 of Sigalioninae \ however, in my opinion, it cannot be ranged among one of the genera, hitherto 

 described. It is closely allied to the genera Leanira and Psamviolyce, but it shows chara eters, 

 that assign an intermediate position between both. All the three specimens are incomplete. 

 Only one possesses all its segments, but it lacks the palps as well as the scales. This worm 

 has a length of about 15 mm., and the number of its segments amounts to 65. Besides this 

 complete specimen there is an anterior fragment, long 8 mm., consisting of 23 segments and an 

 other one with 20 segments and a regenerated caudal region. The head (PI. XXVII, fig. i) is roun- 

 ded, nearly as long as broad, provided with two pairs of semilunar eyes, situated closely be- 

 hind its frontal border; the anterior eyes are somewhat larger than the posterior ones. Between 

 the eyes the tentacle arises with a short basal joint, provided with two small auriculate ctenidia ; 

 its distal part measures about one and a half the length of the head. The buccal segment bears 

 two tentacular cirri, the dorsal one being a third longer than the tentacle, whereas the ventral cirrus 

 is a third shorter than the dorsal one. At the innerside of the basal part of the tentacular cirri 

 a short, digitiform appendage is situated, that presumably represents the lateral antenna. The 

 palps are long and slender, smooth, tapering distally, about three or four times longer than
