nius it is scarcely one fifth of the sa;ne. The lobe diflfers in being 

 much broader at the tip — «• one half as broad again as the base — and 

 In being less curved inward. 



Might clasp: The blade differs from that of iV". JEJnm't^s in being 

 generally broader and in tapering only from beyond the middle of 

 the apical half. The lobe is similar but rather broader on the basal 

 half; the apical half is also much broader -" twice as broad as in N. 

 Ennius, and more than one half as broad as the base of the lobe — 

 and subspatulate in shape, broadly rounded at the tip.

GROUP VI. 



Upper organ: Crest elevated and surmounted by a horseshoe- 

 eliaped, infundibulifotm, spiculiferous ridge; hooks separate, large 

 and rather stout ; tooth as in Group iv. Clasps : Basal process of left 

 blade consisting of a long and slendef finger parallel to the blade, 

 armed at apex and sometimes on upper edge; upper and hind process 

 of loft lobe prominently developed. 



Kisoniades Propertiua nov. sp. Fig. 11. 



Upper organ : ]\Iain body rather short, high and slender. Poste- 

 rior extremity greatly elevated, the crest forming a half funnel-shaped, 

 appressed and gibbous, transverse plate, facing backward and a little 

 upward, and armed with little spicules, which on the margin become 

 very long curving bristles; anteriorly it is supported on either side by 

 a thin, high, compressed ridge, running a long distance forward. 

 Hooks small, stout, strongly curved, pointed, often with secondary 

 denticles near the base, a little divaricate, their bases widely distant 

 and connected by a nearly straight edge, from the middle of which 

 depends a small, smooth, transversely oval, appressed tooth, bending a 

 little forward; at the extreme base of the hooks, on either side, is a 

 recurrent, rather long and slender, blunt denticle, directed downward 

 and a little outward and forward. Arms rather slender, tapering^ 

 shghtly, directed downward and a little forward, at bottom bent 

 abruptly at less than a right angle, a little beyond which they expand 

 and unite beneath, supporting the Inferior armature, consisting of a 

 broad, quadrate, gibbous patch of raised points. 



Left clasp: Main body large, broad and long, increasing but little 

 in width, quite gibbous, longitudinally nearly straight. Blade exces- 

 sively long and slender, the outer portion so twisted .as to be nearly 

 horizontal and uppermost, and in this position is sinuous and directed
