PAGODIA DOLON, new species. 



'Phis s|)(M'i('s is represented ])y two spcciiiKMis of tiic head cxclusivo 

 oi' the froc cheeks. (Ihibella eloiii^ute, sulK|iiadrihitei'al, iiioderatoly 

 convex; a voiy ol)scure trace of a ])osterior pair of short furrows is 

 all that can bo seen on tlie outer surface; occi})ital furrow rather nar- 

 row, clearly inn)ressed, and archino- sliohtly forwai'd at the center; 

 occipital rino- narrow at the sides, increasing- <;i'adually in width to the 

 center, where it is strong and moderately convex; dorsal furrow strong 

 at the sides and fi-ont of the gla])ella. 



Fixed cheeks a little more than one-half the width of the glabella, 

 convex, and sloping outward and downward from tlie dorsal furrow; 

 l)ack of the })alpel)ral lo})es they slope gently to the furrow within the 

 posterior margin and anteriorly moi-e rapidly to the furrow within 

 the frontal I'im; palpel)i'al lobes small, about one-fourth the length of 

 th(; head; ])oster()-latei'al limb short, and marked by a strong, i"ound(Ml 

 furrow within the nai'row, slightly elevated posterior margin; frontal 

 rim roundcil, narrow, and separated fi'om the glabella by a strong, 

 rounded, rather deep furrow, which becomes more shallow in front 

 of the fixed cheeks. 



Surface marked by mimerous medium-sized punctje, with very tine 

 puncta% visible only under a strong lens, betwc(Mi them. 



The largest specimen of the species has a length of 5.5 mm., with a 

 width at the palpebral lobes of 8 mm. ; the glabella has a length of 

 3 nnn., with a width of 2.5 mm. 



This species ditl'ers from the other species of the genus in its shorter, 

 broader glabella, and moi-c convex lixed cheeks.

PAGODIA MACEDO, new species. 



This species is represented by a single specimen of the head, exclu- 

 sive of the fre(; cheeks. (Jlabella elongate, sulxpiadrangular, narrow- 

 ing very slightly toward the broadly rounded, nearly transverse front, 

 as indicated by the cast of the interior of the crust; surface marked 

 by two pairs of shallow furrows that penetrate a short distance on 

 each side and separate the glabella into three subequal lobes; occipi- 

 tal furrow rounded and strong; occipital ring unknown; dorsal fur- 

 row strong, roimded, and clearly separating the moderately convex 

 glabella from the sloping fixed cheeks. 



Fixed cheeks slightly convex, sloping gently from the dorsal fur- 

 row to the palpebral lobe, more rapidly to the furrow within the pos-
