oped, broad, close together, inner corners well defined, apex 

 broad and rounding, or minutely serrate; second lobe inner 

 half reaching nearly to outer angle of median lobe, with two 

 distinct notches and often one additional smaller notch on 

 outer margin; third lobe rudimentary, often raised to an 

 angle at outside of second incision; margin outside second 

 incision uneven or with angular projections. Median incision 

 narrow, not reaching to base of median lobes; first incision 

 with mouth narrow, caused by inclination, towards median 

 line, of the second lobe; second incision well marked. A 

 small chitinous process at inner base median lobe; chitinous 

 process at inner margin of first incision very large, curved, a 

 smaller process at outer edge of first incision; two small 

 plates between first and second incision; second incision sur- 

 rounded by a ring of chitin, thickest at inner margin and 

 sometimes broken at the apex to appear as two processes. 

 The spines of the first, second and third lobes are rather 

 blunt at their apex A pair ofs pines on outer base of each 

 median lobe, one spine ventral and the other dorsal, barely 

 exceeding length of median lobe; a pair of spines from second 

 lobe, one ventral and the other dorsal; a pair from third lobe 

 similarly situated; sharp pointed, a spine about one-fourth, 

 and a long sharp one about one-half the distance to 

 penultimate segment. A small plate at outer base of median 

 lobe, and another, spine- like, usually with one fork, on outer 

 margin of second lobe. Ventral grouped glands: median, 

 none to four; cephalolaterals, six to sixteen; caudolaterals, 

 four to eight.
