 The above synonymj agrees mainly with that of Oeve. fl I have, h >laccd 



question mark- after some in the list; for although they are near enough to A . 

 to BUggesI their union, I am not satisfied as to the wisdom of uniting them. Tli< - 

 following, included byCleve, I exclude from thelist: A . limitanea Schmidt, b Dip 

 erabro pandurella Cleve, ( N . confecta Schmidt, d N. mant Pant.' Thie last 



name is a matter of doubt, there being no text to accompany the figure; but judging 

 from the figure, as I infer Cleve did, [ can nol take the view that it is ded" 



specimen of .Y. erabro. Anyone who reads Schmidt's pathetic appeal/ for guidance 

 out of the labyrinth of confused forms called \ - ib . N. pandura, and A', muiticos- 

 an nol bul realize thai « 'leve has done a large and valuable work in simplifying 

 this part of our nomenclal ure. 



Found al stations 2807, 2808, 2920H, 3013H, Galapagos and Hawaiian islands. 

 Navicula curvilineata Mann, sp. nov. Plate I. II. figure 4.

 extensively curved near the apices toward opposite Bides, and sharply bent at the

 hyaline space much broader on one side of the raphe than on the other Alloineistype ; 

 a distinct border of Btrong, closely set lines perpendicular to the margin, broadest al 

 the center of the valve and narrowing proportionately toward its apices; a large hyaline 

 stauros at the center, aboul one-half the width of the valve. 



Length of valve, 0.128 mm.;width of valve, 0.062 mm. Curved obliqu* - 

 center . 40 to 45 in 0. 1 mm. : radiating striae at center . 75 to so in 0.1 mm.
