Thorax unknown. 



An associated p^gidiuni has a conical, segmented axis, narrow pleural 

 lobes, and smooth, undefined margin. 



Genotype. — Pagodia lotos Walcott. 



The four species of this genus all have a similar type of surface, 

 consisting of shallow punct® of moderate size, with very fine puncta?, 

 visible only under a strong lens, between the larger puncta?. The 

 species now referred to the genus are Pagodia hla Walcott, P. dolon 

 Walcott, P. lotos Walcott, P. macedo Walcott. 



I was at first inclined to refer these forms to Dolichometopus., but 

 they difi'er from the t^q^e of the X'^Xji^x., Dollchometopus svecicus Kx\^\\\., 

 in the narrowing instead of widening of the glabella in front, in the 

 presence of small instead of large eye lobes, short instead of long 

 postero-lateral limbs, and obscure glabellar furrows. 



PAGODIA LOTOS, new species. 



Glabella moderately convex, elongate, with the sides converging 

 very slightly toward the broadly rounded front; obscure traces of 

 two pairs of furrows that extend a short distance inward and back- 

 ward occur upon the sides; occipital furrow strong, rounded, and 

 arching slightly forward at the center; occipital ring of medium width 

 and rounded; dorsal furrow strong but shallow and merging into the 

 transverse furrow in front of the glabella. 



Fixed cheeks about one-half the width of the head opposite the pal- 

 pebral lobes, slight!}' convex, and sloping gently posteriorly to the 

 furrow within the margin and anteriorly to the transverse furrow 

 within the frontal rim; palpebral lobes small, short, not much more 

 than one-fifth the length of the head; a very slight trace of an ocular 

 ridge is shown upon the cast of the interior of the crust, but no evi- 

 dences of it have been seen on the outer surface; frontal rim narrow, 

 rounded so as to give it a thickened appearance, with a slightlj^ flat- 

 tened slope into the furrow back of it; it is separated from the gla- 

 bella and fixed cheeks by a sharp furrow that almost cuts back under 

 the front of the glabella. 



The crust is thick; it appears to be smooth on the outer surface over 

 the glabella and fixed cheeks, with the exception of scattered, shallow 

 punctge. 



The type specimen has a length of 6 mm., with a width at the pal- 

 pebral lobes of 8 mm. 



The associated p3^gidium is convex, subsemicircular in outline, and 

 strongl}^ trilobed except at the margin. Axial lobe convex, conical, 

 and divided by three transverse furrows into three rings and a termi- 

 nal, rounded subtriangular portion. Pleural lobes nearly flat toward 

 the front near the dorsal furrow, and from there curving abrupt!}' 

 downward toward the side and posterior margins; the furrows of the
