KüKENTHAL. Howevei" the Siboga Expedition collected representants of this group at no less 

 as thirty se ven stations. Among them there are three species of Psammolyce^ a genus hi- 

 therto not mentioned from the Malayan seas, with a new species Ps. malayana. Of the genus 

 Leanira, also hitherto unknown in this region, specimens were collected at twenty stations, 

 and six new species described, viz. Leanira coeca, L. Javanica, L. mela7iocephala^ L. sióogac, 

 L. tcntacnlata and L. vulhiris. The genus Sthenelais is represented in the Siboga collection 

 by five species, among which there are three new ones, viz. Sthenelais dicdiosa, S. hetero- 

 chela and .V. malayana. Of the genus Sigalion, which seems to be ver)- rare in the Indo-pacific 

 Ocean, in the neighbourhood of Banda a new species Sig. bandaensis was dredged and also 

 in the vicinity of the Talaut Islands an incomplete specimen was collected ; however Sig. avi- 

 boinensis, mentioned before, was not refound. Of Euthalenessa ocalafa (Mc Int.) specimens were 

 collected at 5 stations, whereas at a station in Madura Strait a worm was dredged, that 

 proved to be the representant of a new genus Euleanira, intermediate between Leanira and 

 Psatnmolyce. 



The sub-family of Acoctinae is represented b\- the giant Eupolyodontes amboinensis, at 

 first described from Amboina by Mal.aquin and Dehorne, and by three other species viz. 

 Eupanthalis nigro-maculata, mentioned by Grube from the Philippines and Polyodontcs atro- 

 inargifiafa and P. sibogae, both new to science.
