that the fourth joint of the palp of the maxillipeds is rudimentary, 

 but in this female it is nearly half the length of the third joint and 

 though rather small can scarcely be regarded as rudimentary. The 

 outer plate of the maxillipeds is said to be without teeth, but in the 

 present specimen there is a row of sparsely scattered very small weak 

 teeth. Stebbing says the mandible possesses no molar, but in this 

 specimen there is a prominent conical process which appears to repre- 

 sent the molar. As will be noticed, the palm of gnathopod 1 is de- 

 jSned by two long slender spines and is differentiated from the hind 

 margin of the joint by a very low angle, and the palm throughout is 

 armed with very fine, closely set teeth, Gnathopod 2 bears a very 

 minute unguiform seventh joint.
