 twelve ; anterior laterals of twelve to thirteen ; posterior 

 laterals of eight to fourteen. Median lobes, large and 

 connate about half their length. Each lobe is rounded 

 at its dorsal extremity, and widened anteriorly, sometimes 

 abruptly. On each side of the median lobes are three 

 slight incisions in the margin of the body ; the margins 

 of these incisions are thickened ; there is a fifth rudimen-

 plates except the first pair are well developed. There 

 are three or four plates on the penultimate segment, 

 and on the ante-penultimate, one or two. The spines 

 are a short one near the meson, on the first lobe, and a 

 long one, lateral, on the same lobe ; third and fourth 

 caudal, of first and second incisions ; fifth, lateral of 

 third incision, and the sixth, between the sixth and 

 seventh plates. On ventral surface the spines are 

 smaller, and the first and second are obsolete ; and the 

 third and fourth on side of the second and third incisions, 

 and the fifth between the fourth and fifth plates. 



The scales of the male are of an elongated, oval 

 form, and much flattened, especially posteriorly. The 

 middles are feebly keel-shaped and the sides are not keel-
