MARPHYSA SANGUINEA. 443 



cence. Dorsum minutely dotted anteriorly. Maxillse with a flattened curve and a 

 strong hook in front. A flange posteriorly indents the great dental plate, which on the 

 left has three teeth in front, and on the right four. The anterior crescentic plate on the 

 right has seven to eight teeth, the left five to six. The azygos plate on the left has six to 

 seven small teeth. The spathulate posterior appendages are dark brown, the ends of the 

 maxilla being pointed and pale chocolate brown. The mandibles have a dense porcel- 

 lanous plate ventrally, the front edge being bevelled to a blunt point externally and 

 having a black spot, whilst the limbs taper posteriorly and are marked by longitu- 

 dinal lines. The foot presents considerable changes in its progress from before backward, 

 the dorsal cirrus increasing in bulk, and the superior lobe increasing in depth. At the 

 tenth foot the superior lobe in profile is broadly conical, the posterior flap projecting 

 superiorly and sloping inward inferiorly. The branchise commence about the twenty-first 

 foot, and continue till within twelve to fifteen segments of the tip of the tail.
