A New Victorian Blind Amphipod. 155 



the second ; the upper margin is concave, and the lower margin 

 straight, with the end of the joint pointed, and bearing three long 

 slightly curved spinules, pointing distally and downvvard ; along 

 the distal two-thirds of the lower margin there is a row of short 

 setse, and medianly on the outer side a few straight spinules. 



Lower Lip (Fig. 5). — The principal lobes are bluntly rounded 

 distally with long incurved setse at the apices, the inner lobes 

 narrow, and fringed with short setse, and the mandibular lobes 

 long and sharply truncate. 



First Alaxillce (Fig. 6). — The first maxilla is very similar in 

 form to that figured by Thomson for N. inonta7ius. The end of 

 the inner lobe is truncate, and bears about six plumose setse 

 (Fig. 6rt). The middle lobe ends in about eight strong, more or 

 less pectinated spines, curving inwards, those towards the inner 

 margin being more toothed than those toward the outer margin 

 (Fig. 6<^) ; the inner margin of the lobe is finely setose. The 

 first joint of the palp is short, and the second long, broad, and 

 <!urving inwards ; the extremity being rounded and bearing a 

 number of short, stout, acute spines, which extend along the 

 inner margin proximally, numbering six in all. Amongst them 

 at the extremity there are also a few longer and finer spinules. 



Secotid Maxillcz (Fig. 7).— The second maxillae are of normal 

 shape. The inner lobe of each is clothed with short setaj and an 

 oblique row of long, stiff", simple setse. The outer lobe has the 

 extremity obliquely truncate, and bearing about six long curved 

 setse. 



Maxillipedes. — In Fig. 8 the maxilliped of the left side is 

 shown as viewed from above. The basos is short, the inner 

 margin straight, and the inner distal angle produced into a lobe 

 or plate, which extends nearly as far as the extremity of the 

 ischios, and upon the summit of the outer half of which are five 

 simple spinules, and on the inner half about four plumose 

 spinules (Fig. 8(z), and a single spine on the inner margin 

 distally. The ischios is short, sub-rectangular, and the inner 

 margin of the large ovoidal distally produced lobe which reaches 

 to about one-third the length of the meros, and is fringed by 

 short spinules along the inner margin, which gradually increase 

 in length distally, and extend for a short distance over the distal 

 •extremity. The meros is twice the length of the ischios. The
