and conspicuously armed with minute teeth, which are borne also, to 

 some degree, upon the outer surface near the tip; at the base it is 

 Tery closely connected with the lobe. Lobe forming a very broad 

 and very short flap, directed upward and a little outward. Its apex 

 scarcely at all rounded, but the outer angle produced into a small, 

 incurved, I'ounded pad. 



Right clasp : Main body similar to that of the other side, with 

 rather deeper excisions and more prominent projections. Blade ex- 

 ceedingly broad and short, its outer surface gibbous, especially near 

 the apex, and tv.isted a little in its course so as to bring its outer 

 surface somewhat upward , Its curve the continuation of that of the 

 main body, as on the opposite side, the lower edge directed a little 

 upward with a sinuous curve, the upper edge curved upward, the 

 apex broader than the bases, squarely docked, the lower angle 

 rounded, the upper square, almost produced and armed M'ith a few 

 minute spinules beyond the central excision of the apical edge; basal 

 process almost entirely concealed; it is a small, narrow, appressed, 

 dentiform, bluntly pointed piece, directed almost straight inward 

 from the base of the upper edge of the blade. Lobe exceedingly 

 broad and very short, nearly twice the breadth of that of the oppo- 

 site side, and having a similar direction, its apical border excised, 

 the angles forming the upper and hind processes, the former well 

 rounded, gibbous and incurved, the latter greatly produced as a pro- 

 longed flap, uniform in breadth, well rounded at apex, gibbous and 

 bent strongly Inward at right angles, crowding against and conceal- 

 ing the basal process of the blade, which it equals in length, and 

 almost coming in contact with the blade itself.

 Wisoniades funeralis nov. sp. Fig. 7. 



Upper organ : ]\laln body pretty short, moderately arched, rather 

 broad and high. Posterior extremity of upper surface broadly and 

 bluntly protuberant in an upward, backward direction, and bearing 

 upon Its swollen summit a small, horseshoe-shaped, gibbous, elevated 

 crest, opening forward and followed in that direction by a distinct 

 furrow ; the crest is completely covered with minute raised points. 

 Hooks small, well rounded, compressed, pretty stout, sharply pointed, 

 divaricate, separated pretty widely at their bases, and supporting 

 there a depending appressed tooth, broader than long, its sides angu- 

 lated, its otherwise angular tip slightly excised. Arms very small at 

 base, expanding backward very extensively; directed straight down-
