puruta lliemsclves, the more so as tlicy arc lar^'or than these 

 latter. The deepness of th« septa and their parallelism below 

 the punctn, as well as the distinet strite at the lower part of 

 the lVii.<tido, contribute to make out of this species a very 

 peculiar one. It has some relation only to L. profande- 

 neptatOf Mcr., frum the Mediterranean. 



1G2. Licmophora monterej'aua, Mrr. (1*1. V. fig, G.) Mon- 

 terey, very rare. [.M.] 



Valve narrow, linear in its upper half, abruptly attenuated 

 in the middle, becoming again linear and very narrow in the 

 lower quarter ; superior apex broadly rounded, inferior in- 

 flated. Pseudoraphe invisible ; strias very fine, about 23 or 

 more in O'Ol mm. Septa dee|) (0"0175 mm.). Length 

 0119 mm., breadth of the valve 008 mm. 



The valve of this species has a form similar to that of 

 /,. remuloidesy Mer., from the Black Sea, but it is a very 

 distinct species, the septa being deep and the lower apex in- 

 flated. It differs from L. grandis by the indefinite pseudo- 

 raphe, which is very distinct in the latter ; the valve is also 

 different. It has no close relation to any other species. 



163. Licmophora pacifica, Mer. (PI. Y. figs. 4, 5.) San 

 Pedro, not rare. [M.] 



Valve broad, cuneate, ovoid in small individuals, sometimes 

 slightly attenuated towards the summit, gradually tajjering 

 from the summit, which is broadly rounded, towards the 

 narrow and subacute inferior a[iex ; margins straight. 

 Pseudoraphe and striai distinct, the latter about 11-12 in 

 O'Ol mm. Girdle-face broadly cuneate, with up[)er angles 

 rounded, walls thick, inferior apex broad. Septa compara- 

 tively deep (average 0*0053 mm.), moderately arcuate ; 

 septal jHincta round, very distinct. Endochrome granular. 

 Sessiliform. Length 0028-0 046 mm., breadth of the 

 girdle-face 0-028-0-036 mm., breadth of the valve ODOSo- 

 0-01 mm. 



This species has a certain resemblance to L. Lyngbyei, to 

 which it seems to be allied ; it differs by the valves being 

 .«<ometimes ovoid, by the septa, which are not so deep, and 

 the absence of sty pes. The valves of larger specimens 

 resemble somewhat those of L. capensis, Grun., but the septa 

 are much deeper than in the latter. 



164. Licmophora paradoxa, var. San Pedro, common. [M.] 



This is not the ty|)e species, as represented by a form 

 which is extremely abundant in VilletVanchc (Mediterranean) ;
