METAPROTELLA SANDALENSIS, N. SP. 



thus, the head carries a pair of spines dorsally and another spine on each side at the 

 point of insertion of the mandibles; further on segment 2, there is a pair of dorsal spines 

 and an unpaired spine at the hinder margin of the segment ; the same applies to 

 segment 3 ; finally in the male there is a pair of robust spines placed latero-ventrally 

 near the anterior margin of segment 2. These latero-ventral spines of the second segment 

 are reduced to mere knobs in the female.

The mandibular palp carries at the end between the two long bristles 8 or 9 short 

 simple setae, and two short feathered setae (Fig. 2). 



Fig. 3. 



The palp of the maxillipede (Fig. 3) has an inwardly directed process at the distal 

 end of the penultimate segment as in M. haswelliana and M. excentrica. For the rest, 

 the mouth-parts are typically those of Metaprotella. 



The rudimentary legs of the third and fourth segments are about half as long as 

 the branchiae; they are slender, and provided at the end with one long and about 

 six short setae — the latter somewhat damaged in the specimens.
