Male. Branches of tlio t'urca 'Vt as long as hroad, closely ;i|i|ii-<>NiiiKite; anal-joint 

 as long as broad. I!, i. of the feet not ending in coiiicMl processes. 



Total length: 0,+ (of the female 0,ti); length of ceplialothorax O/jn, of abdomen 0,i, 

 of furca 0,02; breadtli of cephalotliorax 0,i millini. 



This species has been found in the eastern Atlantic from 32 S. to 52 N. The 

 male was found together with numerous females in a collection from the vicinity ot 

 Uschant.

Shell tliin-walled, with irregular, polygonal nicslics, 4 on the radius. Bars thin, 

 thread-like. Spines few, hair-like, flexuose, twice as long as the r.idius. 

 Diameter of the shell 0,0^. Meshes 0,oo4 to 0,012 millim.

Radial proportion of the tliree shells 1 : 2,.-> : 9. Cortical shell thick-ualled, with 

 circular, regular, six-lobed pores, as broad as the bars. At each nodal-point is a bristle- 

 like spine, half as long as the radius, thus every pore surrounded l)y a corona of six 

 bristles. 



Diameter of the outer shell 0,00, of the cellules 0,ooi millim. 



Found in Janunry 1899 at 45 N. 49 W. in styli- and tricho-pUnikton intermingled. 

 Temperature 12. Salinity 35,54 p. m. 



Owing to the thickness of the cortical shell, tlie interior shells were visible merely 

 as faint shadows, so I am not quite convinced Avhether the shells are 3 or 2. If the 

 lattei- be the case, the species belongs to Halioinina and is then nearest akin to H. Iwrrida.
