Description of the female. The body is stout, but tapers 

 slightly towards the posterior end. The specimen represented 

 by the drawing (PL X. fig. 1) measures only '36 millimetre 

 in length (about y 1 ,-,- of an inch), and it carries a single, 

 moderately large ovisac. The forehead is produced into a 

 small though distinct rostrum. 



The antennules are short and eight-jointed ; the first two 

 joints are large, but the fourth to the seventh are very 

 small; the third and the last joints, which are subequal, are 

 also small, but larger than those between them (PI. XV. 

 fig. 1). The formula shows approximately the proportional 

 lengths of the various joints :

The antennae are furnished with small three-jointed secon- 

 dary branches (PI. X. fig. 2). 



The basal joint of the mandible-palp is moderately stout 

 and bears two small branches (PI. X. fig. 3). 



The second maxillipeds, which are not very stout, are pro- 

 vided with slender and elongated terminal claws (PI. XVIII. 

 fig. 1). 



The inner branches of the first pair of thoracic feet are 

 slender and considerably longer than the outer branches ; the 

 first joint is only slightly larger than the third, while the 

 second is rather more than half the length of that which 

 precedes it. The outer branches reach to near the end of the 

 second joint of the inner branches (PI. XVI. fig. 1). 



The next three pairs of thoracic feet are also slender. The
