Narrawav-Ravmond : A New American Cvbkle. GOl 



Cephalon short, very wide, ('ilal)ella narrou', convex ; cheeks 

 depressed convex, lower than the glabella. Length of cephalon, 4 

 millimeters; width, 12 millimeters. 



Glabella narrow behind, expanding toward the front. Glabellar 

 furrows represented by three ])airs of pits, the second and third pit 

 on either side united into a long depression parallel to the axis, thus 

 forming side lobes to the glabella, l^ehind the third pair of pits, rep- 

 resenting the third glabellar furrows, are a pair of rather deep pits in 

 the line of the neck furrow. Leading diagonally forward and outward 

 from these pits are narrow depressions which bound the posterior ends 

 of the side lobes of the glabella. The top of the glabella is marked by 

 five pairs of pustules, and on the frontal lobe there are several more, 

 all large and rounded. The larger pustules on the top of the glabella 

 are connected in pairs by slight transverse ridges. On the median 

 line of the glabella, just in front of the first pair of furrows, is a rather 

 large circular pit. Opposite the widest part of the frontal lobe of the 

 glabella there are, on the fixed cheeks, two deep pits not well shown 

 in the figure. 



The specimen is broken, so that a large part of both free and fixed 

 cheeks are removed. A part of one free cheek remains, and shows a 

 coarsely reticulated surface. The suture starts very close to the anterior 

 end of the glabella and runs back near the outer margin of the glabella 

 until opposite the first pair of glabellar pits. From that point its 

 course cannot be followed. It cuts the frontal border again a short 

 distance in front of the genal angle. The position of the eye can- 

 not be observed, but it was probably distant from the glabella, as in 

 other species of this genus. Such portions of the fixed cheeks as are 

 preserved are smooth, and sharply differentiated from the free cheeks 

 by the absence of reticulations. The suture is not very sharply im- 

 pressed. The fixed cheeks are depressed, and separated from the gla- 

 bellar lobes by a narrow furrow except opposite the first glabellar pits, 

 where there is a transverse ridge extending outwardly upon the cheeks. 

 Around the front of the free cheeks is a narrow, rounded border, and 

 at the genal angle, a large, divergent spine, of which in this speci- 

 men only the base is preserved. 



Thorax with twelve segments, the sixth one from the front a little 

 wider and more prominent than the others. It does not appear to 

 have borne spines as in Cybele winchelli, but the condition of the 

 specimen is not such as to make this point clear. The axial lobe is
