 Locality: Mediterranean (Villefranche), very common! Adriatic 



(Fola), common. 



L. flabellata is also provided with tour chromatophores but the 



plates are resting not on the valves,as bere, but on the zonal face; 



they are also more rounded. hi ali other respects both species are 



very different. 



34. L. redondina Mer. 



Valve very broad, clongated ovoid, upper part with convex, lowcr 

 part with straight margins, slightly attenuated towards the summit, 

 which is broad, rounded, slightly produced, gradually attenuated to- 

 wards the lower end, which is almost acute. Pseudoraphe very broad 

 (0.002 mm.), lanceolate, striae very robust, 7'/^ in 0.0 1 mm,. with 

 indistinct puncta, parallel, slightly radiate at the upper end. Length 

 o. i35 mm., breadth of the valve 0.0475 mm. 



Locality: Redondo (California), fossil, rare. 



1 bave seen a single valve of this species, which is nearly akin 

 to /.. Ehrenbergii var. ovata; differs from the latter by the form of 

 the valve, the somewhat more distant striae, and the broader and 

 lanceolate pseudoraphe. Could be regarded as a variety of Liciii. 

 Ehrenbergii. 



35. L. remuloides Mer. | fìg. 25]. 



Valve very narrow, composed of two distinct parts of almost 

 equal length, upper part linear, with superior apcx rounded, abru- 

 ptly passing into the inferior part, which is much narrower, gra- 

 dually tapering to the lower apex, the latter not inllated. Pseudora- 

 phe Une, striae very fine. Girdlc face very narrow, linear in its up- 

 per part, with angles subacute. Septa very shallow (0.0048 mm.) 

 but not marginai, straight, very thin^ septal puncta small, round, di- 

 stinct. Length 0.126 mm., breadth of the upper linear part of the 

 valve 0.007 rn'Ti- 



Locality : Black sea (near lalta, Crimea), very rare. 



The valve has some resemblance with that of L. monterevana
